With four different planetary boundary layer (PBL) parameterization schemes (YSU, ACM2, MYJ and NOPBL), a southwest vortex on June 16-18, 2011 is tested using the Weather Research and Forecast (WRF V3.3 version) model and the effect of different schemes on its simulation is preliminarily analyzed. The simulation results show that all the four PBL parameterization schemes can better simulate the eastward shift of rainstorm along with southwest vortex, where the YSU performs best in precipitation, track and intensity of southwest vortex. Compared with the MYJ and NOPBL, the YSU and ACM2 simulate the stronger positive vorticity and higher vertical upward motion in the center of southwest vortex, which are mainly caused by the differences in vertical mixing and entrainment of air above PBLs. Taking no PBL effect into account, NOPBL simulates a greater abnormal surface wind speed and leads to heading on the significant larger surface heat flux and PBL height. The YSU, ACM2 and MYJ simulate comparatively consistent diurnal change of the PBL height and heat flux with less variation at night and greater variation in the day. Among these three schemes, the MYJ simulates larger surface heat flux and PBL height, while ACM2 simulates smaller ones. The surface wind speed is the primary factor for the difference of simulated heat transportation and PBL height.
