摘要：利用NCEP1°*1°资料对“莫拉克”台风的强降水过程进行了假相当位温和湿位涡(MPV)诊断分析.结果表明：假相当位温等值线密集区附近有利于涡旋的发展和暴雨的发生.低层MPV平流对台风强降水的预报具有较好的指示作用,MPV负值中心与强降水中心有较好的对应关系,降水区域一般出现在MPV正、负值对峙区域.MPV1低层为负值,高层为正值,有利于强降水的发生；MPV1密集区与强降水区域有较好的对应关系,MPV1由负值向正值过渡,降水逐渐结束.MPV2由负值向正值的过渡期对应着降水的发生,其正值范围对应着强降水的范围,值越大降水强度越大.

Answer 1

Use NCEP1 ° * 1 ° material for "at" the typhoon rainfall process is a mild wet false potential vorticity (MPV). Results show that: the false quite a temperature isoline concentration near the development and heavy to scroll. Low-level MPV for typhoon heavy consumption of the advection forecast has good indication, rainfall center with negative MPV center has good corresponding relation, precipitation area commonly at MPV is negative, the confrontation areas. MPV1 low-rise negative, high-level for rainfall to occur, MPV1 concentration and regional rainfall has good corresponding relation, MPV1 from negative to positive transition, precipitation gradually. MPV2 from negative to positive correspond to the transition of precipitation, its positive range corresponding to the scope of rainfall, rainfall intensity values.
