Thus, it will be easier to explore them and decide which one you want to use. We will also include the links for the websites or to lower mobile apps. Services to see time at Holy Week We continue now with a collection of apps that you can install on your mobile, and where you will be able to see the time you will do during the holidays. You can also see the forecasts several days in advance. Aemet: The official application of the State Meteorology Agency, where you are going to have official information and reliable forecasts. It has 7 -day forecasts and time information at 8,000 Spanish municipalities, and also has information on rains, adverse atmospheric phenomena and beaches. Links: aemet.es, Google Play and App Store. Accuweather: One of the most important weather apps, so much that many mobile manufacturers applications use their data. It offers two -week forecasts, amounts of rain and even a radar to know when storms approach. Links: accuweather.com, Google Play and App Store. Time: Beyond the officers or internationals, this is one of the most reliable apps to know time in Spain. It will offer you detailed forecasts for the next 48 hours and other generals for 14 days, and there is also information for temperature locations, thermal sensation, clouds, atmospheric pressure, air quality or pollen levels. Link: eltiempo.es, Google Play and App Store. Rain Alarm: One of those magical apps that have been essential for more than 10 years. It does not offer time forecasts, but it is simply a radar that warns you when it is about to rain, and in which you can see the evolution of the clouds. You can configure notices to get to you when the rains approach a certain distance, and you can see the evolution of the clouds in the sky to check how they approach or leave. Links: Rain-alarm.com, Google Play and App Store.

The most viral success of AI is at the same time a symptom of its problems as a daily product

by

The AI ​​had ceased to surprise us. And then the “ghiblation” of images and the Internet arrived He went crazy. In recent days we have lived a fever for converting all kinds of images –And even videos– To imitate the style of Miyazaki teacher and the mythical creations of his Studio Ghibli. The phenomenon has served to make AI at least for a few days again. And that is precisely the problem. Saturated from AI. The appearance of Chatgpt in November 2022 has unleashed an explosion of AI, but after the initial earthquake things have relaxed. Although there have been notable advances, we have “accustomed” to AI, and technology seems relegated to the background for most users. As my partner Javier Lacort said in his reflection of a few days ago, we have seen ourselves immersed in “an universe of impenetrable jargon that was moving the conversation about AI from the initial astonishment to arid technicism.” AI lives from “magical” moments. We saw it with Deepseek A few months ago, and we see it again with the Studio Ghibli style images. Until those “magical” moments occur, the AI ​​does not just set among the general public. There is certainly a moderate use among the population and there are also niches that use it intensively –The program of programmersfor example – but people lack something crucial: an App. What do you use AI? The current options are undoubtedly striking in the creative field and also as assistance for professional tasks, but for now the chatbots have not infiltrated our lives as they did for example internet search engines. They solved a more pressing problem – finding what one was looking for on the Internet – but for the moment AI does not have just replaced them and is not used massively. Looking for an AI that is a google for daily use. The search engine revolution is probably one of the inevitable conquests of the future for AI. We are seeing it with perplexity And the search engines that OpenAi so much Like Google itself They are offering users. These platforms will not totally move to the traditional search engine, but one thing is evident: every time we look more with Chatgpt ” – or any other chatbot – and the growth of that trend seems unstoppable. At the moment Gartner’s cycle of expectations is very well reflected the AI ​​phenomenon. It seems that we have reached the peak of oversized expectations, and we now fall into disappointment avism. Source: Wikimedia. Beware of disappointment abyss. The Association for the Advancement of Artificial Intelligence (AAAI) published these days these days A study conducted by 24 researchers from AI. It included a section entitled “Perception of the AI ​​VS reality”, and in it there was talk of the well -known cycle of expectations of Gartner. The consultant itself estimated that expectations and Hype For the generative AI had already exceeded its highest peak. AI is not so much (for the moment). 79% of the experts surveyed in that study indicated that the current public perception of AI capacities do not correspond to the Reality of research and development in this field. In fact, 90% claimed that this is conditioning the investigation, and of that figure 74% revealed that the areas in which they are being investigated are areas where there are still many expectations. So we are not going to get to the AGI. The most important companies in this area have a common goal: to achieve a AGIthe Holy Grail of Artificial Intelligence. However, these same experts do not have too much hope that we will develop it. 76% of the 475 respondents indicated how to climb (more data, more GPUS to train models) will not be enough to reach an AGI. We need a different approach, and those experts advocate prioritizing issues such as security, ethical governance and a gradual and more responsible innovation instead of this apparent frantic career that does not think about the consequences. Waiting for the next Bombazo of the AI. The fever for “ghibliization” seems to have relaxed significantly and surely in a few days or weeks it is blurred as a striking option more than one AI that excites us to pull – before the Grok 3 censorship imagesfor example – but do not conquer permanently. At the moment it seems that this will continue to be the norm, and now we are waiting for that next pull and perhaps that Killer App that can mark a turning point in the adoption of AI. OpenAI and his rivals need Hype. Meanwhile one thing is evident: what companies sell us (“we are close to the AGI” or “with AI you can do everything Better and faster“) is away from reality. They sell expectations and Hype. TOI remove the best example is OpenAi, which needs that message to continue raising Gigantic investment rounds that allow you to continue burning money As if there were no tomorrow.

“If you have time to learn more about this field”

by

The arrival of artificial intelligence To our life It is no longer a science fiction films. The young people of the Z generation will have to deal with the different forms of integration of this technology in the working world. One of the main councils of the Millionaire and investor Mark Cuban to the Z generation, which begins to join the labor marketis to understand that dominating this technology is not an option, It is a necessity. Mark Cuban’s advice. The millionaire investor Mark Cuban, co -founder of the Broadcast.com video portal and former owner of the NBA team Dallas Mavericks, assured In the SXSW conference that had tried luck in all kinds of businesses throughout his life. However, the millionaire recognized that, if he was a young man with a whole race ahead, he would devote all his time to a single thing: “If he had 16, 18, 20 or 21 years as of today, he would dedicate every minute of the day to learn about ia. Even while he slept, he would hear podcasts about ia” AI is the future and should be prepared for it. In his speech, Cuban emphasized that the AI ​​not only will automate tasksbut it will also create new employment opportunities and transform existing industries. So young people who now join the labor market will have to deal with IA -based tools Or, what is even better, create them. According to Cuban, the key is not afraid of AI, but in hugging it and learn to work with her. This implies acquiring skills in areas such as automatic learning, data analysis and algorithms development. “Those who dedicated the necessary time, will achieve it,” insisted the businessman and investor, whose fortune It is estimated in about 5.7 billion dollars according to Forbes. Skills beyond AI. The millionaire stressed that the AI ​​domain is not limited to computer engineers or data scientists who train AI models. In fact, in an entrepreneur he considers that those who can combine skills in AI With knowledge in other fields, such as marketing, finance or design, they will be the more demanded in the future since the main task of generation Z will be to integrate AI in business processes. The businessman stressed that The works of the future They will require some kind of AI -related skill. Therefore, investing time and effort to learn about AI is an investment in your professional future. A base on which to undertake. Cuban is one of the protagonists of the television program Shark Tank of the American ABC, in which entrepreneurs must captivate investors to put their money in their ideas. That is why Cuban not only invites young people to learn everything they can about. a good job is guaranteed. The millionaire ensures that knowing how AI works can open new venture of entrepreneurship for young A decade ago. “The AI ​​is never the solution. It is a tool,” Cuban said in his speech during the Conference for Entrepreneurs.

While the Portuguese enjoyed sun eclipse, their electrical system had a really bad time

by

Last Saturday, March 29, a partial solar eclipse It was visible in the Iberian Peninsula in the morning. A phenomenon that entertained more than one in this first spring mornings. However, for our Portuguese neighbors it has been a problem for their electricity grid. The absence of the star. During the two hours of eclipse, Portugal lost 560mw of solar generation, which is equivalent to 23% of the country’s electricity production at that time, according to national electrical networks (REN). An imbalance. Solar energy suffered A drop in electricity generation During the astronomical phenomenon, but it was a loss that occurred progressively, approximately 10MW per minute. This situation led to a decline of 8.5% of the electrical production of total consumption, how has expressed a press release THE REN. Return to normal. From 11:30, solar production began to recover at a faster rate, 22MW per minute until it reached its normal intensity. However, the fall was greater than the answer, although it turned to other sources such as hydroelectric and thermal. The balance attempt. Last year, the Portuguese country reached historical records with renewables, covering up to 90% of your demand. However, the eclipse evidenced Portugal’s problem with the storage of energy in batteries and its energy dependence with Spain, how It is observed in the daily balance. An affected interconnection. The eclipse also had an impact on Spain, which ends affecting interconnection Between both countries. At the broader level, the Entso-E network And European Transmission Systems (OST) operators They registered A loss of generation of approximately 21,000 MW during the event. To minimize the impacts, the electric operators of several countries, including Portugal and Spain, they worked together through the service of Short-Term Adequacy (STA)which allows to plan and balance generation and consumption in a seven -day window. Was the impact here very big? In Spain the lack of solar generation, was Supply thanks to wind energy with 31.3% of the electrical production. In addition, after what It has happened in March with heavy rainsfrom the Spanish Electric Red They announced that they had prepared to analyze and anticipate the possible effects of the solar eclipse, guaranteeing the security of the supply and the correct operation of the system.

Every time you think about everything the Romans managed to do, remember that they did it intoxicated with lead

by

Who will not like the Roman Empire? A little over a year ago, thousands of women from all over Spain asked their boyfriends, friends or husbands to How much they thought of the Roman Empire. And, at least according to the meme, the answer was: a lot. What we just discovered hidden in Arctic ice is that, in short, we think too little: the Roman Empire He raised one of the civilizational works more impressive in the history of humanity and did it with absolutely demential atmospheric levels. Lead that they themselves had launched to the atmosphere. Lead, lead everywhere. Examining lead in three Arctic Ice Cores 2,000 years ago, a team of deserting institute researchers They have been able to calculate The level of environmental pollution in Europe between 500 before Christ and 600 after Christ. The data is, to put it in a gentle and restrained way, terrifying. As They publish in Proceedings of the National Academy of ScienceAfter examining the lead isotopes stored on that ice, researchers could create a map of pollution by this metal throughout Europe. Not only that: they estimated their magnitude, the blood lead levels of the inhabitants and even discovered what had caused that enormous pollution. A guilty with name and surname. According to data, silver is at the origin of this problem. Or, rather, the Mining of La Plata. In general and for centuries, the miners melled tons of galena To extract silver. It is estimated that by each ounce of useful silver thousands of ounces of lead to the environment were released. To put it in numbers: “During the 200 years of apogee of the Roman Empire, more than 500 kilotons of lead to the atmosphere were released.” This, always according to the records of the ice centers, is 40 times greater than during the large environmental lead peak of the 70s (after which we began to withdraw it from gasoline, paintings and the rest of the products). And that, of course, there were consequences. We already know that lead is bad for health. Very bad. And not only because of infertility, illness or violence problems: I talk about neurological problems that translate into a considerable decrease in cognitive abilities and concentration. In practical terms, According to DRI researcherslead levels in Roman times had to decrease between 2 and 3 points of intellectual coefficient in the general population. “It does not seem much, but when it applies to practically the entire European population, it is a big problem,” Nathan Chellman explainedCo -author of the study. A problem that, seen in perspective, only increases the myth of the Roman Empire.

I have changed the Apple calendar for Notion Calendar. Now my data and my time live under the same roof

by

Notion introduced its calendar application, Notion Calendar, at the beginning of 2024. I was interested, and much, but limit to Google calendars left me out: most of my events occur in ICloud calendars. Ten days ago they finally announced the integration with ICloud, and there I was, as a user of Notion For years to see how this proposal was and if it is worth making the leap from Apple’s native application. They are not the functions, but the unification My first impression was surprisingly positive. The application is fast, very fast. In me MacBook Pro M1 Proalmost four years ago, the speed with which it opens and the fluidity when navigating between days, weeks or months is impressive. It contrasts remarkably with Apple’s calendar that, without being slow, does not have this feeling of lightness and agility. The monthly view interface throughout its glory. Image: Xataka. The interface is minimalist without feeling empty. It maintains that characteristic air of notion with its soft and white gray tones, but retains its own personality. Visually it is much more pleasant than other calendars such as Google Calendarwhich prioritizes functionality over aesthetics. If you are one di noi And you are looking to optimize every second in front of the screen, the Calendar Notion keyboard shortcuts are a gift. “S” to share availability. “C” to create an event. “T” to go to the current day. “W” to activate the weekly view. “M” for the monthly. It is an approach that is clearly designed for users who prefer not to take off the hands of the keyboard. As Things A function that has conquered me is Availability management. Before, when someone wanted to meet with me, I had to manually send my free holes or use tools such as Calendly That, for some reason, they always made me feel a little impostor. With Notion Calendar, I select the available time blocks, generate a link to the moment and voila. One of those little friction of the day to day that disappear. The availability function. The white holes (not gray with stripes) are the ones that we establish as available. With sharing the link that appears to the right we can facilitate another person our gaps available for a meeting. As an integrated calendly already demands. Image: Xataka. The management of time areas is also remarkable. For those of us who work with people in different parts of the world or when we are organizing a trip, we can see our calendar with multiple schedules at the same time is canonical. And here, Notion does it much more intuitively than Apple’s calendar. Nevertheless, where notion calendar takes muscle is in its integration with notion, in its way of unifying information and time. It is an independent calendar for those who do not use notion, but that integration is the key to this proposal: generate ecosystem, not independent islands. The strategy behind the calendar What we are seeing with Notion Calendar is not just a new calendar application. It is one more piece on a board where Notion is building a complete productivity ecosystem. First was the main application for notes and databases, now the calendar, and not long ago also arrived with Notion mailat the moment on the waiting list. What was previously a product, Notion, now begins to be the center of an ecosystem that continues to grow. Image: Notion, Xataka. Instead of putting everything in a single application that could be overwhelming, Notion is creating independent but totally interconnected applications. It is an intelligent strategy that allows them to compete in each category without sacrificing the user experience. True magic occurs when you link notion databases with dated fields to the calendar. Suddenly, all these elements appear directly on my calendar with my normal events. For example, I have a database with all scripts in notion of the podcastand each one has its publication date. Now I can see those dates directly on my calendar, mixed with my meetings and personal events. The database with the infinite loop scripts that I prepare every day. By including a publication date they have everything you need to appear, if I want, in Notion Calendar. Image: Xataka. This unified vision is not only practical, it is a paradigm shift. It allows to see the events and tasks in a temporary context that previously required several tools. And not only that: you can attach notion pages directly to calendar events. For a meeting I can link the agenda, previous notes or related documents, everything without leaving notion. Towards a more mature experience The iOS version is also very well achieved. Unlike many applications that simply reduce their desktop version, Notion schedule for iOS (It is also For Android) is really adapted to mobile experience. You can choose if you want to see 1, 2 or 3 days when opening the app, something much more flexible than the native calendar. Again: more than the intention of launching a calendar is intuited here. A strategy is intuited that fuses information management with time management. When I saw the initial announcement of Notion Calendar, my first reaction was a mixture of interest and skepticism. Do we really need another calendar application? The answer is in the objective: Notion is not simply building a calendaris building that bridge between information management and time management. It is as if Notion were saying: “You already have all your information organized with us, why not also your time?” And it makes sense. If you spend much of your day in Notion, having your integrated calendar right there makes everything more consistent. Is it worth who does not use Notion? Surprisingly, I think so. Even without taking advantage of integrations, it is a solid calendar application, well designed and with functions that exceed the Apple or Google calendar in several aspects. For me, in fact, he has already replaced Apple’s. And the most interesting thing is to see how Notion is evolving from … Read more

How it affects the change from time to sleep

by

At two will be the three and, as a consequence of that, the dream patterns throughout Europe They will put themselves Above up. Another year. And it is logical: the day after time change, people It takes 33 minutes more than average In going to bed. In addition, they wake up 19 minutes before. That is, what does it affect us? Clear. And not only in quantitative terms; but also in qualitative term. The quality of sleep during the week following time change is frankly bad. Much worse in people between 20 and 30. These are U’s conclusionsn Analysis of sleep patterns of Samsung Health users in more than 40 countries and is interesting. Not because it is extremely representative. After all, the data starts from a huge sample selection bias: they are only its users. However, it does allow us to approach this curious phenomenon with first -hand data. Something that, until recently, was quite complicated. Samsung Health The Spanish surprise. That’s where a surprise comes to us. As I say, the analysis covers more than 40 countries around the world where the time change occurs. Of all of them, Spain is the one who showed greater stability in your sleep patterns. That is, Samsung Health users in Spain are the ones who least affected themselves in their dream for the hourly change. On average, they only delayed bedtime in 16 minutes (the country closest to us was Italy with 19) and the schedule of waking was only affected in five minutes during the first week; two during the second. Why does this happen? Well, the truth is that it is difficult to say. A possible reason may be, of course, that the Spaniards We go to bed very late. That leaves us little margin, on average, to delay the time to go to bed. However, there are other possibilities. As Jose María Olalla has defends for yearsProfessor of Physics at the University of Seville, in countries like ours “it cannot be said that (the change of seasonal schedule) is a bad idea.” Olalla explains that “at summer time it works well in summer and winter time works well in winter. Having summer time in winter is complicated, having the winter time in summer is also complicated. For different reasons, but it will always be a problem.” There are countries where change is a solution and others in which not. That is, the change of time is a simple, coordinated and fast way to adapt the schedule of the whole society to the fact that, in summer, the sun rises before. It is true that it can CAUSE DISPRUPTIONS DURING THE FIRST DAYS or weeks; But taking into account that seasonality is natural, that change would have to occur yes or yes. And the disruptions would remain in one way or another. However, we must not take it very seriously. On the one hand, we do not know how wide the sample in Spain. On the other, as well as Olalla told us“people usually do what they want, even in front of the official schedule. They do strange things, things that often collide with what theoretically is adequate.” Image | Lukas Blazek | Anthony Tran In Xataka | “Cenan at 10, they work at 9”: foreigners are understandably intrigued about how we sleep in Spain

Duplicate the rest of the time of eating

by

In recent months a figure in Mexico has sounded strongly: 40 hours. In many parts of the planet it is a standard to which the nation aspires in labor key thus reducing the weekly workday. There are the First experiments and tests around the world To define if it is plausible to reduce it even to four days a week. Also those who go to the counter, with Elon Musk at the head and Your 120 hours a week. Mexico now debates a new proposal: rest more, but at work. Duplicate the break. In the middle of the national debate for the reduction of the working day at 40 hours a weekthe parliamentary group of Morena has presented a New initiative In the most creative Senate. One that also aims to improve working conditions in Mexico, but differently. The senator Julieta Ramírez Padilla proposed on March 18 a reform to article 63 of the Federal Labor Law for Duplicate the minimum rest period Within the working day, going from the current 30 minutes one hour. The proposal. Framed within the progressive labor agenda of the party in power, it responds to the need to adapt the current regulations (intact for more than half a century) to the physical, mental and social demands of the contemporary Mexican workforce, recognizing that time, not only as a time to eat food or drinks, but as an indispensable condition for the exercise of decent and healthy work. A more “human” pause. In The documentit is emphasized that pauses during working hours are fundamental to prevent exhaustion and reduce stress generated by productive activity. The International Labor Organization (ILO) support this vision Highlighting that breaks are essential to preserve the health of the worker. The senator emphasizes that, within the member countries of the Organization for Economic Cooperation and Development (OECD), Mexico It stands out negatively for the high number of working hours compared to low salary levels, which implies that free time has a “higher cost” For Mexican workers. International examples. Morena’s approach also relies on examples that reflect a trend Towards work models more balanced. In Portugal and in New York, for example, laws establish at least one rest within the day. In Finland, the legal framework grants an hour of pause for every six hours of work, and in Italy there are provisions that give fifteen minutes for every two continuous hours in certain cases. These measures seek not only the preservation of workers’ health, but also to promote more human, fair and productive environments. The Mexican proposal would thus align with a modern vision of work that considers the employee, not only as an economic agent, but as a person with rights, dignity and integral needs. The (“slow”) legal framework. We said it at the beginning, the senator has also contextualized the proposal within a legal framework that has remained unaltered for more than a century (From the promulgation of the Mexican Constitution in 1917). The regulation of the working day in the Mexican Constitution has not been modified since then, and the Federal Labor Law has barely registered changes Significant in the last 50 years, despite the deep transformations that the world of work has experienced. Currently, the chapter related to the working day contemplates eleven legal provisionsamong which are article 58, which defines the day as the time in which the worker “is available to the employer”; Article 59, which allows to agree on the distribution of hours “to facilitate breaks”; and article 61, which establishes a maximum day of eight day diurnal hours, seven night and seven and a half hours for the mixed day. Article 63, which is intended to modify, currently establishes a minimum of half an hour of rest in continuous days. An ambitious agenda. It is the leg that is seen with the proposal to expand the work rest, which adds to a series of reforms that make up the large labor agenda promoted by Morena in 2025. According to El Economista figuresduring the first session of the LXVI Legislature there have been at least 68 initiatives to reform the Federal Labor Law. Among the most prominent: the reduction of the working day to those 40 hours a week we commented, the increase in Aguinaldo 30 days and the creation of mourning permits. The reduction of the day, in particular, is a President’s priority Claudia Sheinbaum and has legislative support since November 2024, with an initiative signed by Deputies Napoleón Gómez Urrutia and Manuel Vázquez Arellano that contemplates a gradual implementation to ensure its economic viability. The future. The truth is that, although the proposal of Senator Ramírez Padilla has gone to Senate commissions for analysis and eventual opinion, his legislative destiny is still uncertain. It will be necessary to achieve a consensus between different political, business and social actors to consolidate the necessary support. In this way, the substantive approach represents an opportunity for rethink the structure of work in the nation from a perspective focused on human rights, health, equity and productive efficiency. The idea of ​​duplicating the rest time within the working day not only responds to international standards, but also to a (growing) social demand due to more just, human and sustainable working conditions.

There are a lot of time apps. Know which one that is most accurate is almost impossible

by

You get up one morning. You look at the application of time on your phone. “100% rain,” or so says. You go to the window and there is a scorching sun illuminating the street. Worse is to consult the application of time, that just 10 or 20% probability of rain and, as soon as you leave, you fall a downpour. The latter is what It has been happening in Spain during the month of Marchone of The rainiest in a long time. Although we blame apps not to predict perfectly, the truth is that interpreting them is not as easy as it seems. How time apps work. Time applications work by combining data from different meteorological models to show us what are the rain forecasts for that day. Each of them is based on a different model, depending on the company behind. These models can be global or regional, having the latter more precision in specific areas. In Spain, Aemet operates with different models such as Arome, MM5 or Reion, although time apps can use models outside our country. Apple and Android. Apple’s time app uses information collected by The Weather Channelsince it has Your own API to provide meteorological data to other apps. If we use an android, such as an Xiaomi, your app works with information from Accuweather. This is precisely what makes each app show us a different fact: each of them is based on the models that it considers, and make predictions on their own. For example, use your own prediction system called Accuweather Minutecast, which combines numerical models with artificial intelligence and real -time radar data to offer hyperlocal forecasts. It does not generate its own weather models from scratch, process information from global models. 100% rain. One of the main problems in the time apps has to do with how they show the information to the user. If we see 70% in the app, probably, let’s understand that the probability of raining in our city is 70%, something that is not completely. In fact, the thing is even more complicated if we go to the forecast for hours and there we see that the percentages are lower than those of the total day. Quite difficult. We start from the basis that the weather prediction It is a complex science due to the dynamic and chaotic nature of the Earth’s atmosphere. Factors such as sudden changes in temperature, pressure, humidity, wind patterns and ocean currents interact intricately, creating a network of interconnected processes difficult to foresee exactly. What is “100%”. There is a common common interpretation with respect to the percentage of probability of rain showing weather applications. It is easy to think that a “100% rain” indicates that it will rain throughout the day throughout the area. The truth is that this 100% means that, in similar weather conditions, it has rained 10 out of 10 times. But it is possible that this new occasion does not do it. The percentage does not determine the rain that will fall, but the statistical mark of how frequent it has been raining in similar conditions. The best way to measure it. The time apps have these limitations, and so they will continue to be until the meteorological measurement system changes. Something that will not happen in the short term. That is why in recent years there is a very booming app: rain radar. Unlike traditional time apps, Rain Alarm is an app that is based on real -time radar data. These radar models do not work in the long term: they use data to make predictions in almost immediate ranges. This is why, with just opening the radar app, we can observe much more precisely the state of the atmosphere. Today, this is the most accurate way of knowing immediately how the weather will behave. And, still, it will still not be accurate. Image | ECMWF In Xataka | Aemet already knows when the storm that is soaking Spain is over. The problem is that another act comes another

Meteorological forecasts are a private preserve. A new AI model wants to democratize the prediction of time

by

A group of researchers has just raised a most striking option: democratize meteorology. Your new weather prediction system challenges traditional systems, very expensive in computational resourcesand make use of AI so that (almost) any of us can become a meteorologist who performs his own personalized predictions. Aardvark Weather. This is the name of a new system of weather predictions that according to those responsible will make any researcher with a desktop PC in a full -fledged meteorologist. The system makes use of AI algorithms and raises an alternative to the conventional systems they use thousands of times more computing capacity. Homemade predictions. The normal thing is that a weather forecast platform takes several hours to process a prognosis. For this, it also needs supercomputers and a team of experts who develop, maintain and display those forecast systems. Aardvark Weather allows you to train an AI model with data from Meteorological stationssatellites, ships or airplanes worldwide and then make predictions based on that data. The investigation. The study Published in Nature this week comes from a group of researchers from the University of Cambridge, the Alan Turing Institute, Microsoft Research and the European Center for Medium-Russian Weather Forecasts (ECMWF). In it they explain how the numerical weather prediction (NWP) is being replaced For automatic learning and neuronal networks that allow “improving the speed and precision” of the prediction. Hyperlocalized forecasts. Among other things the system would allow to offer hyperlocalized forecasts and adapted to specific industries. Richard Turner, automatic learning professor at the University of Cambridge, explained In The Guardian how this model could be used to predict temperatures for agricultural crops in areas of Africa or The wind speeds For a renewable energy company in Europe. The time in the next eight days. Turner adds that the model could be able to generate precise forecasts for a range of up to eight days in the future, when it is normal for precise forecasts to only be guaranteed to five days. Rapid. This system is capable of generating a complete forecast from observational data in a second when processing it in four NVIDIA A100 GPUS, when 1,000 hours-nodo is normally taken in the HRES model of the ECMWF. Ideal for developing countries. There are regions in which these types of forecasts are especially important, and having a “personalized” system would be very useful. Aardvark Weather offers that option according to its creators, because both its implementation and its use is much more accessible. Previous attempts. At the end of 2023 Deepmind precisely Graphcast announceda meteorological prediction system based on AI that had an operation up to 1,000 times cheaper in energy consumption. Its precision was in fact greater than the best of current systems, but it does not seem that development has been implemented in practice. A few months ago Deepmind researchers presented their evolution, called Gencastanother prediction based on automatic learning that improved its predecessor and that of course competes with Aardvark Weather. Everything therefore points to this type of systems are gaining ground and interest, but remains to be seen if they apply massively.
