摘要
利用WRF中尺度数值模式及其同化系统WRF-3DVAR对2010年6月份广西梧州市的两次暴雨过程进行了分析得出:(1)雷达资料的同化对降水模拟的效果会有积极的影响,对于本次研究的两个个例而言,同化雷达资料后的降水模拟都在不同程度上得到改进;(2)多普勒雷达资料同化可以对模式的初始场进行调整,包括风场和水汽场等,进而获取更好的初始条件,改进模拟结果。
Based on WRF mesoscale numerical model and its assimilation system WRF 3 dvar, two rainstorm process of Guangxi Wuzhou is analyzed in June 2010 and it is concluded that: (1) the radar data assimilation have a positive impact on the effects of rainfall simulation, assimilating of rainfall simulation were improved in different degree for the study of two example; radar data assimilation can adjust model initial field, including wind field and moisture better initial conditions to improve the simulation results.
