Google has taken a major step in the field of weather forecasting. The company's DeepMind and research team have launched a new AI model called WeatherNext 2, which makes weather forecasting faster, more accurate, and more high-resolution. This model outperforms the old WeatherNext model on 99.9 percent of variables such as temperature, wind, humidity, and precipitation. Released on November 17, 2025, this model will now make weather information in Google apps like Search, Gemini, Pixel Weather, and Google Maps more reliable. This change will not only make everyday life easier for ordinary people, but will also have a major impact on sectors like energy, agriculture, and transportation.

WeatherNext 2's key strength is its speed. It can predict hundreds of possible weather scenarios from a single starting point in less than a minute. While older physics-based models took hours on supercomputers, this AI model works so quickly on Google's TPU chip. The resolution is also up to one hour, meaning you can now predict the next 15 days' worth of weather in hourly intervals. This is especially useful for extreme weather events like hurricanes, cyclones, or heatwaves, where small uncertainties can cause significant devastation.

The basis of the model is a functional generative network, or FGN. This technique generates multiple possibilities in a single step by adding controlled noise or randomness to the model. Earlier models required multiple processing cycles to generate a single forecast, but FGN avoids this. The model is trained on individual weather elements or marginals, such as temperature or wind speed. Yet, it accurately predicts joints—complex interconnected systems. For example, it can estimate the impact of a heatwave across an entire region or the total power output of a wind farm. For more news updates visit : https://vibrantnews24.com/
