Trackformer 1.1

Trackformer 1.1

Trackformer 1.1 is the frozen public causal baseline for Typhoon Predict.
This release is a research artifact and is not an operational warning system.

Included files

• Three structure checkpoints.
• Three intensity checkpoints.
• Three temporal checkpoints.
• Normalization statistics.
• Calibration state.
• The model manifest and inference contract.

Input boundary

The model uses observed storm history, current and past analysis summaries,
current and past SST summaries, causal nearby-system context, and static
land/sea and terrain features. It does not use JMA, JTWC, ECMWF, GFS, GEFS, or
any other official forecast as an input. Future observations and IBTrACS labels
are used only after the issue time for scoring.

Reproducibility

Extract the model directory at the repository root:

tar -xzf trackformer_1_1.tar.gz

The resulting path is:

models/trackformer_1_1/

The native PyTorch checkpoint files are the supported format. GGUF is not an
appropriate interchange format for this CNN/Transformer weather model.
