摘　　要：以GFS分析资料作为初始场和边界场,使用WRF4.0对国际编号为2022的台风“环高”进行数值模拟,借助中国气象局热带气旋资料中心的最佳路径集、GPM卫星资料和常规地面观测资料对比NSSL和WDM6两个微物理方案在台风路径、强度、降水以及水成物含量上的区别。试验结果表明:(1)NSSL的台风路径和强度相对接近真实台风;(2)NSSL的降水分布相对接近卫星反演结果;(3)两个微物理方案的水成物垂直分布差异显著,NSSL的冰系粒子含量相对较多,云水雨水含量相对较少。从模拟结果来看,两个方案对冰相过程的不同处理导致台风出现不同程度的发展,反映了台风强度和降水对冰相过程的敏感性。Using the GFS analysis data as the initial and boundary fields,this paper numerically simu⁃lated Typhoon Vamco(coded 2022)with WRF4.0.With the best track dataset from China Meteorological Administration(CMA)Tropical Cyclone Data Center,the GPM satellite data and conventional surface ob⁃servations,this work compared the differences between NSSL and WDM6,two microphysical schemes,in the track,intensity and precipitation of the typhoon and the content of hydrometeors.The results are shown as follows.(1)The typhoon track and intensity of the NSSL scheme were relatively close to the real ty⁃phoon.(2)The distribution of precipitation with the NSSL scheme was relatively close to the retrieved result of satellites.(3)The vertical distribution of hydrometeors between the two microphysical schemes differed much,with the NSSL having larger content of ice⁃phase particles and smaller content of cloud water and rain water.It is known from the simulation that the two schemes differed in the processing of the ice phase to re⁃sult in different evolution of Vamco,suggesting the sensitivity of typhoon intensity and precipitation to the ice⁃phase process.
