By using monitoring information of altitude and ground detection data, satellite images etc, methods such as synoptic analysis, dynamic diagnosis and numerical simulation are applied to summarize and analyze characteristics of continuous rainstorms, altitude and surface meso-scale system and meso-scale convective system (MCS) of rainstorms, effects of offshore typhoons on rainstorms in Shaanxi province based on the study of rainstorms and severe rainstorms occurred in the province since 1970. Cases and theory of rainstorms occurred in eastern Tibetan plateau are further recognized and understood. Monitoring, forecasting and early warning of rainstorms in the region are benefited consequently.%以1970年以来发生在陕西的暴雨、大暴雨为研究对象,使用高空及地面探测资料、卫星云图等监测信息,采用天气学分析、动力学诊断、数值模拟等方法,对陕西持续性暴雨、暴雨的高空和地面中尺度系统、暴雨中尺度对流系统(MCS)、近海台风对陕西暴雨的影响等多方面的特征进行了总结分析.加深了对青藏高原东部暴雨实例和理论的进一步认识和理解;有助于对该区域的暴雨监测、预报和预警.
