Study on Mechanism of an Extra Rainfall Process Caused by the Remainder of Typhoon FUNGWONG

摘要

@@ 1 INTRODUCTION Torrential rainfall caused by typhoon landfall required not only sufficient water vapor, but also convective instability energy transported to the storm region. As the storm intensified, positive vorticity extended to mid-level and divergence on t he high-level increased. so that strong vertical motion occurred in the storm region[1-5].
