This research aims to predict severe convective stability indices using a novel model integrating variational mode decomposition and neural network techniques.
Utilized VMD–BiGRU–Attention model for index prediction.
Incorporated GNSS-derived precipitable water vapor and relative humidity as key parameters.
Validated model predictions using extreme rainfall data from 2021 to 2025 across three meteorological stations.
Optimal VMD parameter K for K index is 10 with RMSE of 3.96.
Optimal K for Showalter index is 11 with RMSE of 1.87.
Predicted indices consistently matched observed precipitation, demonstrating effective prediction capabilities.
