一次华北暴雨过程的数值模拟及水汽过程分析

Numerical Simulation and Process Analysis of Moisture Flux on the Rainstorm Process in North China

摘要: 运用WRF模式对2009年7月华北地区的一次暴雨过程进行数值模拟,结果表明:WRF模式比较合理地再现了这次暴雨天气过程;本次暴雨过程的主要输送载体为西太平洋副热带高压外围及低槽前的西南急流;低层水汽通量散度的负值区与降水落区有

Abstract: Using the WRF model,a case of rainstorm over North China is numerically simulated.The result shows that the numerical simulation of this rainstorm process is reasonable.Then some physical parameters which associa
