The great myths of heat that we should avoid in summer

by

The heat wave It crosses its peak during yesterday’s days and today, so staying fresh and hydrated becomes fundamental. This is not always easy: sometimes intuition deceives us, sometimes those who lead us to error are the myths we hear again and again. That is why it is convenient to review some errors in which we can fall easily. Cold water, hot water. To stay hydrated it is essential to drink liquids and, especially, water. But,at what temperature? It depends on what we want to achieve and the characteristics of the heat we are going through. We know that consuming a hot drink can make our body respond breaking. That is why in certain circumstances, drink a hot drink, like coffee can make us cool. But there is an exception: this phenomenon is based on the ability of sweat to cool, but this capacity It looks reduced in high humidity conditions. That is: a hot drink can cool us only if the heat is rather dry. Water of time? If we resort to this technique, we must also take into account the fact that sweat implies a loss of liquids and therefore a greater risk of dehydration. If our objective is not so much cooling and replenishing fluids, perhaps the best idea is to consume “time” water or sympleously fresh (not cold). It is the conclusion of A study Posted in the magazine International Journal of Clinical and Experimental Medicine In 2013. This analysis, focused on seeing how water temperature affected the rehydration process, observed that consuming water at a temperature of about 16º could facilitate the rehydration process. Fresh beer. Taking a fresh beer in summer is common to fight heat. A moderate consumption can have that effect, but as we add alcohol to our body, the chances of the cylinder head shot will increase. First because alcohol works as a vasodilator, which can alter the distribution of heat in our body. This effect It makes alcohol more dangerous in winter, when you can transmit a false feeling of warmth, but it can also affect how we feel in summer. Perhaps the greatest risk of going with beer in summer is, however, hydration. This drink has a diuretic effect that can make us lose water at a rate greater than the replacement, which can approach dehydration. Fans, yes or no. The fan is one of the most useful tools when fighting heat, but it is a tool with its limitations and even inconvenience. TO Air conditioning differencefans do not cool the air. What they do is to facilitate that our body heat is blurred by sending us colder air than the one around us. The problem is that, after a certain temperature (about 35º), the air that comes to us is not colder than the one around us, so the fan will not help us. Moisture It is also important since these devices work worse in very dry environments. They can also cause us problems when we use them for a long time, such as when we sleep with them, disseminating allergens or drying the atmosphere of our stay. Ventilate spaces: Not so simple. Keeping our very ventilated home is important throughout the year, but correctly handling ventilation in summer can also help us refresh our home, improving thermal comfort and saving energy. Now, It is not right simply With opening the windows, there are important factors to take into account. Of course, the time is one of the keys: if we want to refresh our house it is best to do it before the arrival of the daytime heat or once it has dissipated. We will also otimize the ventilation if instead of opening windows to right -handed and sinister we open windows in opposite points of the house in order to take advantage of the thermal difference to generate stronger currents that are taken with it the heat and moisture.

Taiwan believes having found the mythical planet 9 of the Solar System. Instead of looking for his light, he has been looking for his heat

by

The countless frustrated attempts to find planet 9, a hypothetical giant gas in the confines of our solar system, have aroused the ingenuity of some Taiwanese scientists. Short. For years, astronomers have swept the sky in search of the weak reflection of sunlight that should get to us from planet 9, a demonstratedly ineffective task. Now, a team of researchers has changed the rules of the game with an ingenious idea: instead of looking for it, they have tried to detect their heat. Well, they have found two very promising candidates. Context. Beyond the orbit of Neptune, in an icy and dark region known as the Kuiper belt, the orbits of several objects seem to be grouped in a way that challenges chance. The trajectories of these transneptunian objects (TNos) align as if an invisible hand were guiding them. The most accepted hypothesis to explain this behavior is the existence of an unknown massive planet, the planet 9. Of existing, this distant world would have a mass of between five and ten times that of the earth. The problem is that it would be more than 400 astronomical units, so its light would be incredibly dim. To put it in perspective, Neptune is “only” 30 UA or 4,496 million kilometers. If we can’t see it, maybe we can feel its heat. A team from the National University Tsing Hua in Taiwan believes to have the strongest track in years on the real existence of the most wanted object in our neighborhood. The results of their study are not final, but they reach two promising candidates. Every object with a temperature above absolute zero emits thermal radiation, that is, heat. But while the light decreases with the distance following a relationship of the inverse of the fourth power (1/d4), the heat only decreases with the square of the distance (1/d2). This abysmal difference is the argument used by researchers to focus their search on the heat signature of planet 9. A needle in a haystack. The team resorted to the data of the Akari Space Telescope of Japan. Throwed in 2006, Akari dedicated his useful life to sweeping the full sky in distant infrared light, the perfect range to detect the thermal brightness of the planet 9. And he did it from space, without the interference of the Earth’s atmosphere. Astronomers set out from a list of unprocessed Disssdl detections: more than 5.2 million signals with many false positives. After limiting the search zone, eliminating known objects, filtering sources contaminated by galactic dust clouds and excluding static objects, which seem to be at the same point in observations separated by months, the list was reduced to 393 candidates. Of 393 candidates for two. He touched his hands dirty. The investigators visually inspected the images of the 393 candidates. They ruled out weak detections, artifacts at the edges of the sensor and, above all, the impacts of cosmic rays that can be perceived as a specific source of heat. After this thorough process, there were only two candidates. Two heat points that appeared where planet 9 was expected, had the predicted brightness for the theory and showed the expected movement: they were detected in the same place in a period of 24 hours, but there was no trace of them in the same place six months later. All to demonstrate. The two candidates were baptized as FISSDL J0250422-15011 and FISSDL J0301112-164240. But to verify if these two heat points are really a single object moving in an orbit compatible with planet 9 will need new observations in visible light, with sufficiently powerful telescopes to detect its weak optical brightness and measure its movement with precision. If confirmed, the discovery would not only solve one of the greatest mysteries of modern astronomy, but would revolutionize our understanding about how our own system was formed and evolved. Everything is to be demonstrated, but at least we have a hot trail to continue hunting. Image | ESA, Hubble, M. Kornmesser, CC By 4.0

Meteorologists have a name for what is happening in Spain: heat dome

by

While a good part of Spain prepares for first heat wave From this summer, meteorologists study what is happening in the atmosphere to answer questions such as how we have reached here or when the extreme heat will end. The first wave is approaching. The State Meteorology Agency (AEMET) launched a Special notice for the arrival of this heat wave. The notice will enter into force tomorrow, Saturday 28, but the most intense days of this episode that will last at least until Tuesday, July 1 will be expected. The heat waves are, By definitionextreme events in which temperatures exceed statistically defined temperature intervals for the time of year. That is, the situation is remarkably hotter than one would expect for these days of the beginning of summer. Heat dome To explain what is happening at the atmospheric level, meteorologists resort to a metaphorical term, the dome or heat dome. Physicist Francisco Martín León explains this concept in a piece for Meteoredalthough the term speaks in itself. The main “ingredient” in this phenomenon is a height anticyclone. When one of these anticyclones remains static in a given area, it tends to catch air masses at lower levels. This air also tends to accumulate heat due to the high insolation associated with atmospheric stability. A shared dome. The peculiar atmospheric situation is not being the exclusive heritage of the Peninsula as on the occasions in which we talk about the “Iberian oven” but the dome formed by the anticyclone also covers a good part of the south and southwest of Europe. Bad news if we consider the temperature increase lived during the last weeks in Mediterranean waters and the risks involved in this anomalous accumulation of thermal energy. 42º and climbing. In addition to its special notice, Aemet has activated various notices due to extreme temperatures. For now it is yellow and orange notices, although it is convenient to pay attention to how the situation advances. For today, the agency expects maximum between 34º and 36º in good part of the country, with some areas that could reach 40º. As the days go by the situation could get worse, with areas such as the Guadalquivir Valley exceeding the 42nd mark. Some predictions They even speak of Andalusian cities that reach the 44th Celsius. An additional problem will be the minimum temperatures. They are expected to fall from the 23rd-25º “in large areas of the southern half and the Ebro valley.” That is, part of the country will encounter “tropical nights” that will make due rest of the people suffering them. Meteosalud. In addition to Aemet notices, Meteosalud, under the Ministry of Health, has issued its own evaluation of the areas with greater and lesser health risk these days. This evaluation warns of high -risk areas in areas of the northern peninsular such as the Ebro Rivera in Navarra, the central area of ​​Huesca or the central depression of Tarragona.

Planting the heat of Córdoba in summer is impossible. I have tried a personal thermal dissipator to at least try

by

I do not discover anything to anyone if I say that In Córdoba it is hotter than on Charmander’s birthday. We have many good and beautiful things, such as the Mosque-Catedral, Medina Azahara or the Alcazar of the Christian Kings. This is the only city in the world with four assets of humanity, The first person to fly did in Córdoba And for having, we have even A traffic light with artificial intelligence. But if there is something we have and that we are left over, it is, without a doubt, heat. There are those who fight this excess of Celsius degrees leaving Fuengirola (also called Córdoba II). Others put in front of the fanunder the air conditioning or call the friend who has a pool at home with the excuse of “how long without seeing us.” I, for my part, have tried in a less conventional way. I have done it with a personal thermal dissipator of Sony: the Reon Pocket Pro. It is put below the shirt, but so you can see the size better and where it should be placed | Image: Xataka Terus dissipator … what? I know it sounds a bit strange (not as much as Go to the gym with an exoskeletonwhich also made), so we go in parts. The Sony Reon Pocket Pro is a portable thermal device that cools and heats the part of the body with which it comes into contact. That part is precisely the upper back area, just below the neck. It is not a portable air conditioning, much less. How does it work? The device incorporates two independent thermal modules in the rear that cool or heat according to the context (then we return to this) and a fan that extracts the heat from our body and expels it above. The two thermal plates alternate, so that when one reaches a certain temperature, the other is deactivated and activated so that the sensation of freshness is constant. These two plates work independently and cool or heat | Image: Xataka How do you get? We have to place it so that the two plates touch our body and the upper air exit protrudes slightly from the shirt. If we wear a shirt, we can use the adapter. The device is slightly curved, thus respecting our natural curve, and has a pair of flexible tubes that are placed around the neck and keep it subject. These, by the way, are not seen, but they stay under the shirt. And yes, they are noticed. The air exit should stay above the neck of the shirt | Image: Xataka These moorings should also be placed below the shirt | Image: Xataka Is it comfortable? Depends. It is acceptable if we take it while we walk or We are perfectly seated (With a straight back), and that weighs about 200 grams. If we change posture, for example, more reclined in the chair or lying on the couch, impossible. As for noise, I have not appreciated that the fan makes more account noise. I wear it right now and in my office, where only the noise of my mechanical keyboard is heard, I do not appreciate it in excess. However, I must say that it seems like a device too large and that finding the exact location in which it must be placed is complicated. It is not so “of remove and put” as perhaps you could expect a device like this, but you have to place it well, in its place, if we want it to work correctly. That it is more or less comfortable will depend, in large part, on the position we adopt | Image: Xataka Ok, but it cools? Let’s go to the point. The Reon Pocket Pro can be used in two ways: manual or automatic. If we establish it in manual, we can configure (via buttons or via app) the target temperature and the device will be in charge of reaching it. If we establish it in automatic, it will use, in addition to the data of the device itself, those of the Reon Pocket Tag to determine the objective temperature depending on the ambient temperature, the humidity and even the exposure to direct light. The problem is that this small sensor works well if it is abroad. If we carry it in the pocket (it is fully designed to hang it on the keys or in the pants), the data can vary. In any case, it works well and if we are going to use it in a room like an office for a while, just leave it on the table and forget about it. Reon pocket tag | Image: Xataka As for the sensation, it is … curious. As soon as we put it, we will notice how the surface of the neck begins to cool (or heat). It is almost instantaneous. With the passage of the latter, the sensation of freshness is improving and, thanks to the two thermal modules that are alternating, it is constant. And yes, cool. Now, the reality is that the one that is: the sensation of freshness, within that it relieves even going down the street, is very localized in the area near the location of the device. The cold mode sensation is the same as if you carry a bag of ice cubes on the back. In heat mode, it reminds me a lot of thermal blankets for neck pain. Image | Xataka On the battery. Using it at a medium cold temperature, the device lasts practically one day. A working day endures it without problem. At a lower or greater temperature, depending on the way we choose, less autonomy. In that sense, the use of hot mode spends more than cold mode, but for obvious reasons I have not used it just during these days. As for the load, it is completed in approximately three hours. So… Is it pleasant? It is, especially when you put it … Read more

Ourense is synonymous with heat and 40ºC in summer

by

The ourensans are more accustomed to the heat of what we would commonly think for one of the Galician provinces. The municipality has broken the record Several times in the last decades of the highest temperatures marked in Europe. It is not that it has exceeded the absolute figure, but has exceeded other typically torrid cities on the same dates, and for a notable difference. The Coasts of the Atlantic Ocean have always been famous for being cold and wet. Even in summer, Galicia enjoys softer temperatures than the rest of the peninsula due to pure oceanic climate. Well, at least in almost all its territory, because if we take into account Ourense this premise may not be fulfilled. Embedded between green mountains and bathed by the Miño, Ourense is, without a doubt, somewhat peculiar. And, although it is of a very Galician character, and it has nothing to envy landscapes and atmosphere to its sister provinces, instead of having a purely oceanic climate sometimes There are more typical episodes of subtropical areas. This has led to the records of maximum temperatures several times over the last decades. Galician, but hot The previous occasion was in 2017, when Ourense beat the maxim during the month of May. At that time, the city reached 37.6 ºC (together with Ribadavia), which meant the breakdown of the European record for those dates. At that time, the entire peninsula lived a very hot climate for spring, but especially the Ourensana capital, which recorded throughout the month sustained temperatures above 30 ºCusually reaching 36 ºC. In 2013, in full heat wave of Julio, Ourense reached 45 ° Cwith a thermal sensation of up to 51 ºC, while in Seville, a typically hot city, the 45 ° C were reached, and that in Europe The maximums were around 40 ºC. In 2012, this city was also among the hottest spring, reaching temperatures comparable to those of the southern peninsular. In July 1990, the extreme figure of 42.2 ºC was reached in Ourense a record number, again, for those dates. And so the account becomes long, with numerous similar episodes. How do you explain that Ourense is one of the hottest cities being so north? However, we do not need to go back back in time to identify the peculiar warmth that the climate of this Galician province entails. According to the weather file prepared by Meteoblue During the last days of the current month of June the maximum temperature has risen until touching the 35 ° Cwhich, once again, consolidates it as one of the European regions with the warmest climate. A subtropical climate in Galicia In 1900, Wladimir Peter Köppen designed a Climate Classification System. This consists of a global natural climate classification that identifies each type of climate with a series of letters that indicate the behavior of temperatures and rainfall that characterizes this type of climate. According to this classification, Galicia is in a pure or subocean oceanic climate, identified with CWB and CWC figures. However, Ourense does not enter into this classification, but corresponds to a CSA climate, that is, a typical Mediterranean climate. The typical Mediterranean is characterized by dry and hot summers, with average temperatures above 22 ° C and wet and rainy winters, with soft temperatures. The colder the month, according to this system, the rainiest results; Already the reverse, the hotter the month, the drier results, although they do not have to coincide exactly. In an oceanic climate, such as the rest of Galicia, however, summers are much cooler than in areas with subtropical or Mediterranean humid climate. Why does it depart so much from the rest of the region? The answer is undoubtedly in the orography. The Valles del Miño and Sil They produce a geographical barrier that directs the weather. Thus, there is a kind of thermal well promoted by a thermal investment effect. This phenomenon occurs when the coldest layers and close to the ground cannot ascend since they are blocked by a still cold layer. This generates a layer of clouds and calima over Ourense, which causes an increase in temperatures in the area due to a local greenhouse effect, where radiation from the bouncing surface. Thus, although the morning dawns fresh, as the day takes place, solar radiation heats the air that remains imperturbable in the same area. This orographic configuration, in fact, would have been responsible for THE EXPLOSION OF LIFE that the region has lived In the last 120,000 yearsafter glaciation. As indicated by the geographers of the Department of Xeography of the University of Santiago de Compostela, the diversity of temperatures responds to the existing contrasts between the different areas of Galician geography. These contrasts, in turn, must, as we said, to the so particular geographical configuration of Galicia in combination with the distances that are even the Atlantic Ocean. Thus, both in the interior valleys of Miño and Sil, and in the interior depressions of Verín and Monforte, there are very high temperatures compared to northern Galicia, where you can register up to twenty degrees less for being subjected to fresher winds, from the ocean.

The atmosphere has been stuck in a “extreme heat generator” on Spain. That means something: a hard summer

by

The first fortnight of June has brought us more typical temperatures at the end of July or even August: there have been numerous days in which wide areas of the southern peninsular have seen the thermometers exceed the 40º line. The problem now is not that heat stays with us throughout the summer, the problem is that it may go more. Same trend. The heat seems determined to settle on the peninsula, or at least that is what can be detached from models such as those used by the European Center for Middle Term weather forecasts (ECMWF). To understand why, we have to look higher towards the atmosphere. About 1,500 meters high. According to Explain The physicist, disseminator and researcher at Aemet JJ German in his account Twitterwe have the track in the forecasts on the temperature at height at 850 hectopascales (HPA), which usually refer to an approximate height in the atmosphere of 1,500 meters, the low troposphere zone. The temperature at this level tends to be related to the temperature that we see at soil level, so it can serve as a reference for how temperatures will evolve in the coming days. According to data shared by German, we not only find a temperature above the climatological average (an anomaly above the 5th Celsius), but the situation will last, with the possibility that this anomaly approaches 10th towards the end of June. “This is barbarity: far from returning to balance as normal, atmospheric dynamics on the Iberian Peninsula seem to get stuck in an extreme heat generator,” explained in its publication. Looking at the map. If we focus on The map Prepared by ECMWF, we will also see that heat will remain foreseeably installed on our heads. The forecasts indicate that during the next ten days the almost entire peninsula will be under the influence of temperatures above 20º to 850 HPA, with large areas above the 24th and with some points, the 28th barrier temporarily exceeds. What’s happening. In a second TweetGerman explained what is happening. According to the expert, a Dana located west of the peninsula and a dorsal (an extension of high pressures associated with an anticyclone) would be responsible for the situation. A situation that would be seeing aggravated by the low atmospheric movement, thus achieving what German refers as a “static equilibrium point.” The result: heat and more heat. The result is the intuitive: this warm episode seems to be sentenced to extend over time, at least during the next week. The maximum in a large part of the Peninsular South They could stay above 36º and promptly above 40º.

The heat arrives and you want to drink cold water. Science has a much more effective idea: drink hot water

by

Summer arrives and with it staying well hydrated becomes an imperative. The heat will surely make a glass of cold water even more appealing, but it is likely that we have ever heard that the water, better hot. Is it a myth or is there a reason behind? Drink water. Drinking water is the important, hot or cold, keeping our body hydrated is the main objective. Despite this, drinking hot water or cold water is not exactly the same: our body can react differently Before the stimulus. This is what science tells us about it. Better digestion. Hot infusions are a desktop classic. Coffee, tea or chamomile are usual choices to close the food, especially if it has been copious. When consuming these drinks we are, indeed, Drinking hot water. In doing so we are moisturizing our body and allowing water to help the flow of food in our digestive system. Part of the effect we owe it to the mere fact of being drinking water, but there are some studies that suggest that the temperature could play an important role in the digestive effect of this desktop habit. A Study published in 2016 Focused on newly operated patients, he observed that the consumption of hot water in recently operated in the colon had a “positive impact” on subsequent intestinal movements. Do you lose weight drinking water? In 2023, a group of researchers conducted An experiment in which a group of participants had to consume a certain amount of warm or hot water after meals, while the rest had to consume the same amount of water at a temperature without specifying the temperature. As reported by the team, the group that consumed hot water lost body mass more speed than the control group. This could explain why we associate drinks such as tea are associated with weight loss. The diuretic potential of some infusions and the benefits that others have on intestinal transit could be related to the mere act of drinking hot water, but the truth is that the tests we have are very limited, so we still cannot add the hot water to the eternal list of candidates for “miracle diet”. Cool ourselves with hot water. It may seem Little appealingbut hot infusions are a classic in some of the most scorching environments in the world. Our body is about 37º Celsius: if we consume something at a higher temperature, our body will absorb that heat. It doesn’t seem like a good plan. And yet it works (although not always). The key, The experts point outis how our body dissipates heat through sweat. A hot drink can activate nervous receptors by sending the signal that the temperature is greater than what is actually, which in turn does that our body begins to sweat and thus begin to dissipate heat through the water we expel by the skin. To sweat, of course, it should also be hydrated. When may not work? Drinking hot water to reduce our body heat can be a bad idea in some contexts, mainly When moisture is high. Moisture makes sweat dissipated, with it, avoiding it heat. Temperature and hydration. Hot or cold, we began by saying that the most important property of water is that it hydrates: our body needs this liquid to stay alive and drinks are the main source to obtain it. Now, we know that Not all drinks hydrate the sameDoes the water do it indistinctly of its temperature? Maybe not. A Study published in 2013 He calculated how the water temperature affected the rehydration process. A too hot water could induce sweat, causing us to lose some water at the same time we rehydrate. By contrast, water too cold or too hot can also make us drink less. The team observed that a better rehydration was achieved when consuming fresh water, about 16º, a temperature similar to that offered by tap water.

Heat, pests and a problem of productive capacity

by

The production of olives, and therefore that of olive oil, has been living a turbulent years. The drought in 2023 put the harvest in check but the return of the rains last year gave the producers a respite. Now the agricultural sector in Jaén has expressed concern about what comes in front. Crisis or regression to the average? Pessimism in forecasts. The coordinator of organizations of farmers and ranchers of Jaén (Coag Jaén) has shown her Concern for this harvest of the olive. Although the association indicates that it is still early to talk about forecasts for harvest, some areas of the province already estimate crops between 30% and 40% below the views last year. Producers They point out several causes Behind this pessimistic forecast, which cover warm episodes as well as the risk of pests, but also the natural phenomenon known as the olive grove. A little propitious meteorology. One of the factors that concern the coordinator is in meteorology. Specifically, the warm episodes we have been living since the end of May. The heat has advanced this year in which the thermometers in several areas of Andalusia came to exceed 40º before the end of the spring month. Of course, this problem may not be extensible to other regions. The rains in the mediterranean environment They could have a positive impact in the crops of the area. Farmers now expect temperatures not to fall during the beginning of the summer in order to reduce the risk of the arrival of Prays. And the pests. There are several pests that threaten the oil harvest this year and among them the most popular is perhaps that of Prays (Prays Oleae), also the so -called olive moth. Already in May, the Junta de Andalucía He warned of “algal levels of attack” associated with this plague. The life of this insect is closely associated with the olive grove and has several annual generations that can affect this plant. The data of the Board are based on the animal’s philophagous generation, which affects the plant leaf. Now the experts They follow the Antophagous Generationwhich affects the plant of the plant. The algodoncillo (Euphyllura Olivina) It is another pest that concern producers. It is another insect whose name derives from the “cotton” appearance that surrounds the nymphs of this invertebrate. The olive grove. Voccas or contracting is a natural phenomenon that occurs in numerous crops. The vocation occurs when crops have difficulties in producing for full performance for two consecutive years. As explained by the coordinator, although in some Jienenses areas the production of last season was “average”, some olive trees “already accuse the verter.” Looking for clues. As Coag Jaén points out in its statementit is still early for truthful estimates of what this year’s harvest will be. As indicated by the Agrarian Association, the olive grove has two “critical” moments for the demand for culture water. The first is the flowering that usually occurs between April and May; The second is maturation, in September. There will be so much to wait a few months before having a definitive idea about what the Cosecha will be like, but what do we know exactly about flowering? The pollen can give us a track. According to Coag Jaén’s own data, the pollen concentration peak in the air occurred on May 19, with 7,711 grains per cubic meter, “far from the maximum peaks of other years when 15,000 grains were exceeded”, in the words of the association.

Heat ends, but storms arrive

by

The heat is being the undisputed protagonist of this week at the weather. However The warm episode He has his days (or his hours) counted in much of the Peninsula: as of today the extreme heat will live with rains and storms: some communities will have to alert for very different phenomena. Variopintos phenomena. Meteorologists foresee that the warm episode that affects the peninsula will fade in the next few days and that at the beginning of next week the instability will be the dominant tonic. The transition will not be simple: during the next few days some areas will see the arrival of rainfall and storms while others Taguada vs. dorsal. Let’s put some context to understand what is happening at the atmospheric level. A few days ago we saw an arrival of an Atlantic anticyclone and an associated dorsal. The dorsal are areas of high pressures that extend from a high pressures center lengthening the scope of anticyclonic time. The stability associated with high pressures, along with other factorscontributed to a high insolation that warmed the air of the peninsula until it brought us to the current situation. However meteorologists They announce now that a trough display in the next few days the dorsal. That is, from a situation we move on to the opposite, with a region of low pressures associated with a storm changing the meteorological panorama. A heat pause. And how this translates: then that instability will take possession of peninsular meteorology. Some areas will begin to see storms today, but it will be from Sunday, with the arrival of the dorsal, which these are generalized. Heat warnings and storm warnings. The peculiar transition between two weeks marked by opposite phenomena will leave A singular notice map of the State Meteorology Agency (Aemet), a map in which yellow and orange warnings coexist due to maximum and storm temperatures (and also yellow notices for rains). In this sense, today it will be the most unique: 14 autonomous communities (all peninsular except Murcia) will see active notices throughout the day. Of these highlight orange notices due to temperatures of up to 40º Celsius in the Sevillian countryside; and orange warnings for storms inside the Cantabrian cornice, from the Asturian southwestern to the inner Bizkaia. In unknown terrain. Spring is a transit station where changes in the atmospheric situation are not entirely strange. However, we can talk about an anomalous season in terms of meteorology: from a drought we spend some of the months with more rainfall than we have record. Now we return to one more panorama in the tonic of recent years: with a summer that is advanced leaving us extreme heat during the last week of May. To know what will happen during the real summer we will still have to wait a few weeks. In Xataka | The reservoirs are almost 22% above the average of the last decade.

The problem of heat arrival is not just the 40º planned by Aemet: also the “tropical nights”

by

Heat has come and with him a more annoying phenomenon than the high daytime temperatures: the so -called “tropical nights.” Bad news for those who have problems reconciling with heat. Tropical nights. The warm episode that this week is manifested on a good part of Spain threatens to bring maximum thermometers above 35º in various areas, even above 40º in areas such as the Guadalquivir Valley. However, beyond the maximum, There is another fact to pay attention: minimum temperatures. We talk about “Tropical nights“When the minimum night temperatures do not fall from the 20th Celsius. That will be precisely what happens in areas of the southern peninsula and in the Canary Islands throughout the week, according to the forecasts of the State Meteorology Agency (Aemet). According to Aemet In an informative note Dedicated to the warm episode, the minimum temperatures will rise throughout the week, more slowly and intense than the maximum, yes. The minimums above 20º will affect areas of the southwest quadrant and the Mediterranean coast, also extending to the Ebro Valley during Saturday. On the edge of the “equatorial night.” In fact, Aemet’s forecasts They anticipate minimums that could remain around 24th towards the end of the week in areas of Malaga or Cádiz. This implies that some areas are on the edge of the call “Equatorial Night”, Term that refers to the nights on which the minimums do not fall from the 25th. A anticyclone, and a Dana? But what is happening so that spring has ended so abruptly? Much of the fault has an anticyclone inside located on the waters of the Atlantic, around the Azores. The influence of high pressures will leave us a great atmospheric stability, explains Aemet, with “practically clear skies and high insolation.” But there is even more: from Wednesday, the appearance of a Dana between the Canary Islands and the Gulf From Cádiz I could drag with it a mass of warm, dry and with suspension dust, first to the south and then towards the peninsular center. The result of this would be the additional increase in the temperatures that we will see throughout the second half of the week. Notices for extreme temperatures. Thus, the agency has issued several notices for extreme temperatures for tomorrow Wednesday and for Thursday by maximum temperatures between 37º and 39º. Is there an end in view? The big question now is when this will end. And the truth is that it is still early to venture since uncertainty predominates towards the end of the week, says Aemet. According to Explain the agencyit is “likely that as of Saturday 31 the Dana will dissipate” and that instability in the peninsular northern increases, in turn giving clouds to reduce the failure of these days. In any case, we will have to wait to see if these predictions are confirmed. In Xataka | The reservoirs are almost 22% above the average of the last decade.
