Google DeepMind WeatherNext 突破飓风预测，开源模型并更新 Weather Lab
原标题：WeatherNext: AI model achieves breakthrough in forecasting cyclones
AI 摘要
Google DeepMind 发布 WeatherNext 系列 AI 天气预报模型，利用功能生成网络高效生成集合预测，可在 TPU 上不到一分钟生成 15 天预报。模型在低分辨率下仍能准确预测飓风强度，并开源代码和权重，同时推出 WeatherNext 2 和 mini 版本，以及更新 Weather Lab 平台。该突破将飓风预测提前时间增加一天以上，相当于气象学十年的进步。

Our model uses Functional Generative Networks (FGNs) to efficiently produce ensembles of different predictions, which captures the inherent uncertainty of the weather. We can now generate a single 15-day forecast in less than a minute on a TPU, empowering forecasters to quickly evaluate the probability distribution of potentially devastating tail-risks. Last year, our system produced 50 predictions at a time, matching global physics models. This year we scaled our ensemble size to 1,000 members,
