Abstract:Diagnosis is performed of the rainstorm from Typhcon 16 of 1992,indicating that the rainfall is generated through high-level pump ing operated with a low-level cyclon ic flowfield,a high-level anticyclonic flowfield, and a deep vapor-saturated layer available,and that the raingush enhancement is attributed to the typhcon moving into the easterly wave system or a vortex or trough in westerlies,thus leading to intensified warTn advection over the rainband and increased pumping at high levels. Eventually, some remarks are given as to the research and prediction in the scope of typhoon rainstorm.
