台风Wipha云微物理特征数值模拟

 借助非静力中尺度模式ARPS，利用美国国家环境预报中心（NCEP）全球逐6h最终分析资料（FNL）与中国气象局MICAPS系统地面资料和探空资料进行四维同化作为初始场和侧边界，每6h利用实测雨带反插调整模式初始水汽场，进行三重嵌套细网格模拟，利用模式结果研究0713号台风Wipha不同阶段暴雨云微物理过程水平和垂直特征，对了解台风暴雨不同发展阶段云结构和强降水形成机制具有科学意义。

Numerical Study of the Characters of Typhoon Wipha Cloud Microphysical Processes

With the non-static mesoscale model ARPS (Advanced Regional Prediction System), by using the NCEP/NCAR global final analysis data, and the global surface and sounding data under MICAPS (Meteorological Information Comprehensive Analysis and Process System) assimilated in 4 dimensions as the initial field and lateral boundary conditions, the initial moisture field is adjusted according to the surface accumulated rain of each 6h, and the triple nested simulation is conducted to produce 3 dimensional high time-spatial resolution data including cloud microphysical process data. Then the main horizontal and vertical microphysical characters of the Typhoon (Wipha) are analysed. The results are significant for understanding the cloud structure and the precipitation forming mechanisms of the Typhoon storm. It is found that the ice phase microphysical processes are the key storm mechanisms in different periods. The melting graupel confirms that the rain is the most important mechanism. The intensity of the production of graupel varies in accordance with the Typhoon.
