Research Highlight
Operational high‑resolution Global Forecast System (GFS) T1534 model fidelity in capturing the monsoon onset over Kerala
The Indian Summer Monsoon (ISM) onset over Kerala (MOK) marks the beginning of monsoon rainfall. Accurate prediction of MOK is essential, as it is linked to large-scale circulation and rainfall variability. While several observational studies have established criteria for identifying MOK such as increased rainfall, strengthened low-level westerlies, and enhanced moisture transport, the ability of dynamical models to capture these features in short to medium range prediction remains less explored. This study evaluates the high-resolution GFS-T1534 model’s fidelity in simulating MOK. Results show the model captures key features, including strengthening of low level jet, rainfall increase, Tropospheric temperature change, and strengthened 600 hPa westerlies, with reasonable accuracy.
