摘　　要：利用常规观测资料、卫星云图资料、雷达资料和NCEP(1°×1°)再分析资料,对2008年10月海南省特大暴雨过程的演变特征和形成机理进行深入研究,结果表明,热带低压外围螺旋云带发展过程中的MCS是造成此次海南特大暴雨的直接影响系统,充沛的水汽,低层强烈的旋转辐合,较强的垂直上升运动是这次降水发生的有利条件。Based on the conventional observation data,satellite cloud data,radar data and NCEP（1°×1°） reanalysis data,the evolution of the features and formation mechanism of heavy rain in October 2008 Hainan were studied.The results show that the developing MCS in the Tropical low pressure external spiral cloud bands is caused by the direct impact of heavy rainfall in Hainan system.And abundant water vapor,the strong convergence in the lower level,the strong vertical ascending motion is the favorable conditions for the precipitation.
