　　为了进一步研究台风“梅花”影响过程中暴雨的产生机制，对台风引起的暴雨过程有更好的把握，利用常规观测资料及 NCEP/NCAR 1°×1°的6 h 再分析资料，对2011年8月5日—8日受台风“梅花”影响，山东部分地区出现的暴雨过程进行诊断分析。结果表明，干冷空气的卷入对台风强度的减弱有重要的影响；干空气与暴雨落区有一定相关性，暴雨区发生在干空气团（相对湿度<50%）前部，600~850 hPa处于湿度≥90%的干、湿气团交界处；暴雨区发生在 MPV1、MPV2正负值交界处，靠近 MPV1负值区， MPV2正值区一侧，对应高空850h~925 hPa等MPV1线密集，925 hPa等MPV2线密集。

In order to further study the typhoon‘Muifa’effects in the process of rainstorm caused by typhoon mechanism, to have a better grasp of the rainstorm process. Based on the NCEP 1°×1° reanalysis data on 5th to 8th August 2011, a study on the heavy storm in part of Shandong Province under the influence of the typhoon Muifa was conducted. The results showed that: the involvement of dry cold air had important influence on the weakening of the typhoon intensity. Dry air had some relevance with the heavy rain area, the rainstorm region lied in front of the dry air (the relative moisture was lower than 50%), where was the junction of the dry and wet air (the relative moisture was bigger than 50% between 600 hPa and 850 hPa). Meanwhile, the rainstorm region, which agreed well with the MPV1 and MPV2, was close to the negative areas of MPV1 and the positive areas of MPV2. Accordingly, there existed an isoline denseness area of MPV1 between 850 hPa and 925 hPa and MPV2 at 925 hPa.
