WeatherNext

What it is

Code and pretrained weights for WeatherNext 2, a medium-range global atmospheric forecasting model that also tracks tropical cyclones, along with the earlier GraphCast and GenCast models. It loads initial conditions such as HRES data, runs autoregressive rollouts at 0.25° or 1° resolution, and includes a cyclone tracker plus training loss code. Weather researchers and forecasters use it to run, evaluate, or fine-tune the published models on TPUs or GPUs, starting from a Colab notebook.
