摘要
利用MM5模式对0604号强热带风暴"碧利斯"和0605号台风"格美"进行数值模拟和水汽、动力、热力学分析。分析结果表明,"碧利斯"与"格美"前期都没有与北方冷空气发生作用,后期前者受到西南季风槽的影响得到大量水汽能量补充,在台风路径左侧产生强降水,后者的水汽、动力和能量条件较差,在华南产生的降水相对弱一些,但在北方冷空气的影响下在黄河中下游部分地区造成洪涝灾害。
Numerical simulation is made on typhoon Bilis and Kaemi（2006 ）, the simulated vapor, dynamic and energy fields are analyzed, and two forecast models for preciptation of landfalling typhoons are summed up. The analysis results show that Bilis was affected by the southwest monsoon and got a lot of vapor and energy supplies, while Kaemi did not have such supplies, so precipitation in the south of Kaemi is smaller than that of Bilis. However, Kaemi caused flood calamity in the middle and lower reaches of Yellow River area when its circulation interacted with the cold air from the north.
