Simulation sensitivities of the major weather regimes of the Southeast Asia region

This study evaluates the Weather Research and Forecasting model's ability to simulate major weather phenomena [dry conditions, tropical cyclones (TCs) and monsoonal flow] over East and Southeast Asia. Sensitivity tests comprising different cumulus (Kain-Fritsch and Betts-Miller-Janjic) and micr...
