“碧利斯”引发强降水过程的湿位涡诊断分析

Diagnostic Analysis of Moist Potential Vorticity for Heavy Rain Caused by "BILLIS" Typhoon

摘要: 利用NCEP 1°×1°再分析资料,计算了2006年第4号强热带风暴"碧利斯"过境引发强降水过程的湿位涡(MPV)和假相当位温(seθ),分析了其湿位涡中尺度时空分布特征,探讨了湿位涡发展、减弱与暴雨增幅、减弱的相关性,并结合假相当位温分

Abstract: Based on the NCEP 1°×1° reanalysis data,the mesoscale spatio-temporal distributed characteristics of moist potential vorticity of the heavy rain triggered by the 4th strong tropical storm "Billis" in 2006 are
