边界层参数化方案对台风“莫拉菲”热力和动力结构特征影响的对比
Comparison of the thermal and dynamic boundary layer structure with different boundary layer parameterizations during typhoon "Molave"
摘要
Abstract
Base on the mesoscale WRF mode,the performance of simulating the structural feature of the boundary layer in the South China Sea is evaluated and the thermal and dynamic structural feature in the boundary layer under 6 kinds of boundary layer parameterizations scheme are compared and analyzed.Compared with the sounding data,the results show that the simulation of geopotential height and temperature is not greatly affected with the different PBL scheme.The simulation with the BouLac scheme is closest to the observed data.The MYNN scheme and YSU scheme produce weaker result than that of the BouLac scheme.The PBL schemes on the simulation of tropical cyclone track and intensity have a significant different to the result without PBL schemes.The simulations of structure of tropical cyclone are significantly difference with different PBL schemes;the difference is not limited in PBL.关键词
