Tropical cyclone formation binary dataset

This binary dataset contains a specific customization of the National Center for Environmental Prediction (NCEP)/final analysis (FNL) data for ML applications, in which environmental conditions relevant for tropical cyclone (TC) formation during 1999-2023 are extracted for a range of forecast lead times (0-72 hours). The dataset is designed as multi-channel images centered on TC formation locations, with a positive and negative directory structure that can be readily input from any ML applications or common data interface. With its unique structure, this dataset provides users an opportunity to conduct ML application research on TC formation as well as related predictability at different forecast lead times.
