| 摘 要： | 以第五代中尺度模式（MM5）为基础,本文对一次南京大暴雨个例进行了三组数值模拟试验,研究了模式湿物理过程参数化方案的组合对梅雨暴雨降水预报的影响.试验结果表明：模式的积云对流参数化方案的选用对南京大暴雨的预报至关重要,积云对流参数化方案的选用比边界层参数化对暴雨数值预报的影响大;对20km模式分辨率而言,采用单一的积云...

| Abstract: | In this paper,a series of numerical experiments are carried out on a Nanjing heavy rainfall case in the middle and lower reaches of Yangtze River(MLYR).Using PSU/NCAR non-hydrostatic MM5,the impacts of model convection parameterization schemes(CPSs),boundary layer parameterization(PBLs) and microphysics on the forecast of Nanjing heavy rainfall are discussed. The CPSs of model physics is more important to Meiyu heavy rainfall forecast in the MLYR than that of PBLs.As 20-km model resolution is concerned,the ... |
