While Spain was pending the rains, something strange was happening with the polar vortex

The meteorology of the month of March has been marked by the wave of storms that have left intense rains throughout the Iberian Peninsula. While many monitored attentive to the possibility that the channels overflow in their surroundings, in the high layers of the atmosphere there was an important phenomenon, the disruption of the polar vortex. New animation. NOAA (National Oceanic and Atmospheric Administration), The agency responsible for analyzing weather and weather in the United States, has shown us the disruption of the polar vortex occurred during last March. He has done it through a new animation in which the drastic changes can be seen The polar vortex. First of all, remember that Polar vortex It is an intense atmospheric current that transports cold air around the pole at stratosphere. In winter, the polar circle stops receiving sunlight so the air at the height of the stratosphere cools. In contrast, the warm air of sub -reliable areas continues to be tempered at these altitudes, which leads to expand north. The terrestrial rotation makes this pressure a powerful current of air that surrounds the pole in winter. Although the current is always active, it suffers important changes throughout the year. The first change is in intensity: it is during the winter months that the winds of this current reach greater force, reaching its middle peak towards the beginning of January. The second change is in the direction. Due to the inclination of the earth’s axis, approximately between spring and autumn, the current moves away from the pole to the torque that loses intensity because the sun enlightens the pole again, heating his stratosphere and reducing the contrast with lower latitudes. This implies that high latitudes the current stops moving from west to this but does it from this to west. When the vortex breaks. However, the current can suffer a sudden change, a disruption. These cases are usually due to sudden stratospheric warming in the pole. This “pushes” the current out. This is what happenedexplains the NOAA, last March 9: rapid stratospheric warming generated a disruption of the current that has led her to circulate in reverse and intense in high latitudes. Return to normal. If a disruption occurs during winter, it is common for the vortex to return to its usual circulation after one of these disruptions. If this disruption occurs during spring, it is likely that the circulation will pass to its summer shape, outside the pole. It can be expected, due to the dates, that the evolution of the vortex now takes it back to the average. Last year We saw a vortex disruption that reversed the dominant direction of the wind in early March, however the vortex recovered its direction and intensity of these dates before reversing its spring channel. Graph in which the speed and direction of the stratospheric wind is illustrated in the 60ºN latitude. The fine blue line marks the average evolution in the 1991-2020 period; while the thickness marks the evolution between 2024 and 2025. The shadow represents the variability observed and the pink forecasts. Laura Ciasto/NOA “Like an atmospheric diva. ” This year the models indicate that this will not be the case, which implies that we are facing the change in earlier in the records since 1958. This concludes the “season” of activity of the polar vortex, a season marked by a high intensity circulation and important volatility. A closure that has lived up to the season, according to NOAA. “For a good part of this winter season, the polar vortex has been strong, stretched, and not very interested in interacting with the troposphere. But like a real atmospheric diva, the polar vortex had a last ace in the sleeve, disintegrate in a spectacular way and bring with him some cold air,” NOAA itself explains in a piece in his blog dedicated to the polar vortex. And then what? In the result of all this is that the circulation of the vortex is now maintained in northern Europe and that can reach affect weather of the continent. How this arrival will depend on factors such as the interaction between this mass of air and the troposphere or what low latitudes could reach circulation in that month of April.

The question is no longer whether the rains return or not. The question is what is happening this spring with the meteorology of Spain

“Have you enjoyed the sun?” The meteorologist Roberto Granda asked Yesterday at noon. “Well, hurry, because from Tuesday afternoon the clouds and rain return to much of the country,” he continued and, effectively, it will be like that. In fact, from Wednesday to Friday, we will see enough rain in the west of the peninsula. But, of course, the key issue is no longer If the rain comes back or not. We have that clear. The key is what is happening this spring to meet all this rain. But, first of all, why don’t it rain now? Basically because during these last days an anticyclone has managed to close the hall of deep storms that had emerged in the Atlantic. However, it is not one of those anticyclones that remain on our heads until weed. While I write this, the anticyclone is already giving way for cold air masses to get into the country from the southwest. But that It will end. From Tuesday (and, above all, Wednesday) it will rain a lot in the Guadalquivir, Guadiana and Tajo basins. In fact, According to the weather index that measures the rarity of phenomenathe rains could be remarkably intense in the southern zone of the central system. Again. But the thing does not end there: another blockade. As Víctor González explainsboth the European and the American models have begun to draw an anticyclonic block in northern Europe in their departures. That is, a structure very similar to the one that has accompanied us in March. However, it is still early to know what will happen (because there are several options). The blockade in northern Europe Direct the storms Towards our latitudes. However, we need not an anticyclone about our heads. If in the end a dorsal is assembled on the peninsula, we will notice a “tempered and slightly unstable atmosphere”; But if the blockade is broken in the south, we can return to a situation very similar to last month. Is April a new March? Not so fast. That is alone one of the possibilities that arise. It is not clear that it will happen (And, much less, with that intensity). However, what we are seeing is already interesting in itself: in a country so prone to persistent stability, this uncertainty is really very striking. Hence, this article cannot end with the question we always ask ourselves “What can we expect?” We are entering An atmospheric dynamic that, beyond the rains this week, We can expect anything.

This is what is happening

If you have a PC with Windows 10 either Windows 11 And lately you have noticed that your tools to control Fans or RGB lighting They have stopped working, it could be related to a recent security detection in Windows Defender. As The Verge points outseveral users have seen how Microsoft antivirus marks these applications as a possible threat, which prevents its correct operation. A controller at the point of sight. The origin of the problem seems to be in Winring0, an access controller to the kernel that many of these tools use. In recent days, Windows Defender has begun to identify it as a “Hack Tool”, which causes related files to be quarantine and that the applications that depend on it stop working. Winring0 is one of the few free controllers with low level access to the system, but its security history is not brilliant. In 2020, he was registered as CVE-2020-14979a vulnerability that, According to Inbibeallows reading and writing in the system memory to obtain high privileges. The big question: why now? It is not clear why Windows Defender has hardened his criteria at this time regarding a problem identified years ago. A possible explanation is the reinforcement of Windows security policies after the incident with Crowdstrikewhose failure in a security update caused problems in systems around the world. It is also known that Microsoft has decided to harden the requirements for controllers. A problem that directly affects users. Winring0 block has not only caused many hardware monitoring tools to stop working, but also caused strange behaviors in some systems. Some users They have noticed That their fans began to turn at maximum speed without control after the quarantine of the controller, since the applications that managed them stopped working properly. Image shared by one of the affected users The first indications suggest that applications such as Fan Control, Steelseries Engine, OpenRGB, Free Hardware Monitor, Capframex, MSI afterburner, Omenmon, Zentimings and Panorama9 have been affected, leaving many users without the possibility of monitoring temperatures, controlling fans or managing the RGB lighting of their equipment. The developers are trapped. The developer’s dilemma is that Winring0 was a free and free solution to access low -level hardware in Windows. Some companies have chosen to withdraw and develop their own solutions, such as SignalrGB, which Winring0 replaced in 2023 with a SMBUS owner controller. However, many open source projects cannot afford to create and certify a new controller, since Microsoft demands a digital payment signature for any software that access the kernel. What options do users have? If Windows Defender has blocked any of these profits in your team, there are several alternatives: • Update the application. Some developers are working on winring0 versions. • Find alternatives. There are similar tools that do not depend on this controller. • Add an exception in Windows Defender. Some developers suggest this optionalthough it entails safety risks and is not recommended.

What is happening and why you can’t suddenly send content

Let’s explain What about the chromecast who have stopped workingan extended mistake that many users around the world are reporting. Simply, using several Chromecast models have stopped being able to do it, and not even restart them. We are going to start this article explaining what exactly this error is and what is happening. Then we will specify the models to which it seems to be happening, and we will end up talking about what you can do about it. What’s happening Suddenly, there seems to be an error that is affecting some Chromecast models around the world. Simply, cannot send content to the devices. This means that when you enter the mobile in a video or content and the option to send to the Chromecast is chosen, this does not work simply. In addition to the chromecast becoming pisapapeles, another problem is that You cannot access your configuration through the Google Home application that serves to manage them from the mobile. It is as if they had stopped working. Apparently, an error that says that You cannot identify the chromecast. This error occurs although so far it had worked. In other cases, the error seems to point to an old firmware. What devices affect This error seems to be affecting To the oldest Chromecast modelssuch as the second generation or the Chromecast Audio. The most modern models such as the Google TV or the Chromecast Ultra work without any problem, only affects the old. How to solve the problem The worst of this problem is that Currently you can’t solve it. If you throw for classic solutions such as restoring the device or restarting it, this does not fix anything. Chromecast will still not work and nothing can be done. It is normal to think that In a few hours or days, google throw an update that serves to solve this problem. Therefore, you must pay attention to the updates of the Google Home OA app that your chromecast can receive.

Something totally unexpected is happening in Ukraine. Suddenly, North Korea soldiers have disappeared

Since November 2023, Ukrainian forces and intelligence in the United States have calculated that up to 12,000 North Korean soldiers have moved In Kursk’s Russian region to stop the Ukrainian offensive. In recent months we have known The strategy that pyongyang troops followedlarticles that lead to the battlefieldand even Ukraine captured soldiers who betrayed the misinformation with which they seemed to have arrived in Europe. However, something has happened in the last two weeks. North Korean paper. CNN had through interviews with Ukrainian troops that many of the northorean soldiers deployed were using extreme combat methods that remember tactics of the cold war. With a formation focused on sacrifice and unwavering loyalty to Kim Jong Un, these soldiers had demonstrated fierce resistance, although they were suffering from mass losses, With about 4,000 dead or injured. His behavior on the battlefield, in fact, had baffled the Ukrainian forces, since instead of surrendering, Many prefer to immolate themselves with grenades or use desperate strategies How to shed your protective team to move faster. In fact, several teams captured to the fallen soldiers revealed that They carry only the minimum to survive: Limited water rations, without shelter clothes and with backpacks full of ammunition. Although they carry modernized versions of the AK-47 rifle and other more or less recent Russian teams, their lack of armor and preparation for current war technology was accelerating its wear on the battlefield. And suddenly, they are no longer. One withdrawal? According to the New York TimesNorth Korean troops sent to Russia to strengthen their offensive against Ukraine They have disappeared from the battlefield for two weeks. It is possible, as analysts explain, who have been removed from the front after suffering those devastating losses we were talking about. Its deployment in November 2023 generated alarm when the measure was interpreted as a significant climb of the conflict. However, in just three months, The number of troops was drastically reduced Due to the lack of coordination. According to Ukrainian sources, the Russian strategy consisted of Send them in waves through mined fields and under intense firewhich resulted in a high number of casualties. Now, the withdrawal is not necessarily definitive, since it is evaluated the possibility that these soldiers return after receiving a resentment or if the Russian controls find more effective ways to use them in combat. Impact of the Ukrainian offensive on Kurk. The Ukrainian incursion in the Russian region of Kursk in August 2024 surprised the Kremlin and altered the dynamics of the conflict. For the first time in more than a decade of confrontations, including the Russian in large scale in 2022, Ukraine seemed to take and maintain territory within Russia. This movement, although criticized by some as an unnecessary wear of resources, is seen by President Volodymyr Zelenskyy as a key tool to press in future peace negotiations and a strategic barrier against new Russian offensives in the northeast of Ukraine. Although Russian forces have managed to recover about half of the lost territory, the Ukrainian presence in Kursk It is still a challenge for Moscowforcing Putin to balance their military resources without weakening their main operations in eastern Ukraine. The North Korean alliance. It We have counted in the past. The sending of North Korean troops seems to be part of A broader cooperation strategy between Moscow and Pyongyang. Kim Jong Un, by supporting Putin, Search in return assistance in military technology and diplomatic support. In addition to troops, North Korea has supplied Russia millions of artillery and missile projectiles, covering approximately half of the armament that Russia uses daily at the moment. In return, Moscow provides oil, food and improvements in North Korean weapons. In fact, the recent restoration of the Mutual Defense Treaty between the two countries reinforces this relationship, which reminds of the era of the cold war. The North Korean future. Although the withdrawal of North Korean soldiers suggests that their initial deployment did not have the expected impact, Your possible return is not discarded. Russia could reconsider its integration strategy with these troops, perhaps avoiding their use as a simple shock infantry and improving its coordination with local units. Besides, The situation in Kursk continues to evolve, with new Ukrainian offensives facing a growing Russian resistance. Meanwhile and as we said, the alliance between Russia and North Korea continues to consolidate, and along the way increasing tensions with the West. As the war continues, the participation of external actors such as North Korea could become an even more relevant factor in the development of the conflict and in the global geopolitical balance. And Trump is still missing, although it is about to see how he will.
