WRF模式中微物理和积云参数化方案的对比试验
THE EFFECTS OF DIFFERENT PHYSICS AND CUMULUS PARAMETERIZATION SCHEMES IN WRF ON HEAVY RAINFALL SIMULATION IN PRD
摘要
Abstract
In order to study the impact of the parameterization schemes in the WRF model on rainstorm simulations, a heavy rainfall on 14 May 2010 in Pearl River Delta (PRD), Guangdong province is simulated. The study was carried out with four cumulus parameterization schemes (KF, BMJ, GD and G3) and six physics parameterization schemes (Kessler, Lin et al, WSM 3, WSM5, Ferrier (New eta) and WSM6 scheme) under a horizontal resolution of 3km. The results indicated that the Lin et al scheme, coupled with the Kain-Fritsch(KF) scheme, can accurately simulate the location and intensity of the heavy rainfall. However, the other schemes deviated in the location and produced less rainfall. The results of an analysis of unstable stratification and vertical convection velocity also indicated that this scheme can accurately simulate the reality of the rainfall. Generally, when coupled with the Kain-Fritsch (KF) scheme, this scheme is more accurate in simulating rainstorms in the PRD.关键词
