台湾地形对海棠台风影响的数值模拟研究
Numerical simulation of typhoon Haitang(2005) and the topographic effect of Taiwan island
摘要
Abstract
The Weather Research and Forecasting (WRF) model is used to study the evolution of typhoon Haitang and the topographic effect of Tainwan island. Although the variable track could not be reflected exactly, the model can capture Haitang's evolution of intensity and structure, especially its weakening during landfall, as well as precipitation distribution in Taiwan. Analysis of mesoscale system shows that the sub-vertical circulation which is inspired by the interaction of typhoon Haitang circulation with CMR terrain generates strong upward motion in precipitation area. And horizontal wind transports warm and moist air to this area and provides plenty of vapor for supporting convection development. The special correlation between typhoon Haitang circulation and CMR terrain plays an important part in typhoon Haitang precipitation.关键词
