英语翻译摘要：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

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.
