WRF模式对高影响浙江型台风微物理和边界层参数化方案的优化试验
OPTIMIZATION TEST FOR MICROPHYSICAL AND BOUNDARY LAYER PARAMETERIZATION OF HIGH-IMPACT ZHEJIANG TYPHOONS BY WRF MODEL
摘要
Abstract
This paper selected nine Westem Pacific typhoons that had highimpact on Zhejiang in recent years to find a relatively good parameterization scheme for local typhoon forecasting based on the WRF mesoscale model.We evaluated the simulating performance on typhoon track,intensity and precipitation under different microphysical and boundary layer schemes.The results indicated that for microphysical schemes,the Kessler and SBU-YLin were better for simulating typhoon track andintensity while the SBU-YLin had better precipitation scores,smaller errors and better correlation than the Kessler,but the missing report rate was comparatively high,when it comes to Zhejiang precipitation.For PBL schemes,the MYNN2 and BouLac had higher proportions in the best typhoon track and intensity schemes,while the BouLac had a better precipitation effect,which had smaller precipitation errors,better correlation and better TS scores,particularly in more-than-heavy rain levels or during the 12 hours before typhoon landfall.Therefore the SBU-YLin and BouLac schemes were more suitable for simulating Zhejiang typhoons.In addition,the simulated precipitation was less than the reality,with the absolute errors significantly larger in the coastal region of Zhejiang.The opposite is true for the inlandarea.The rainfall errors corresponded well with terrains in Zhejiang.关键词
