| 摘 要： | 利用NASA提供的热带测雨卫星(TRMM)资料和NCEP/AVN模式的实况分析场研究了热带气旋“威马逊”(2002)的演变过程、结构和降水特征.对要素场及倾斜对流有效位能诊断分析发现,降水的分布和强度对热带气旋的发展有很好的指示作用.针对MM5的几种积云参数化方案进行了数值试验,初步研究了各方案在热带气旋定量降水预报(QPF)中的作用.

| Abstract: | TRMM and NCEP/AVN products are taken to investigate the structure and rainfall feature of TC Rammasun(2002) based on the analyses of the associated large-scale environment. It shows that the structures of the NCEP/AVN-derived environment fields, such as horizontal and vertical wind, as well as Slantwise Convective Available Potential Energy (SCAPE) are in good consistence with the 3-D distribution of TRMM derived rainfall. Furthermore, TRMM data is also used in the numerical experiments with meso-scale model MM5 to evaluate the performance of different cumulus parameterization schemes in quantitative precipitation forcasts (QPF) of TC. |
