摘　　要：通过对1991-2011年福建省内3小时雨量大于100mm的台风突发性大暴雨的个例分析，探讨台湾及台湾海峡的地形因素对台风突发性大暴雨发生的影响作用，总结出“南风加强型”、“气流交汇型”和“东风加强型”三种有利台风突发性大暴雨的环境形势场。通过对“南玛都”、“龙王”台风突发性大暴雨的典型个例的综合分析和数值模拟试验，初步揭示台湾岛及台湾海峡地形对福建沿海台风突发性大暴雨产生和影响的机制。Based on case studies of sudden typhoon rainstorm （more than 100 mm within 3 hours） in Fujian Province from 1991 to 2001, the influence of the Taiwan Strait terrain on the sudden typhoon rainstorm is investigated. It is found that three types of synoptic circulation patterns can provide favorable condition for the rainstorm process, namely the enhancement of southerly, the convergence of jets and the enhancement of easterly. Through diagnostic analysis and numerical experiment of representative sudden rainstorm process of typhoon ＂Nanmadol＂ and ＂Longwang＇, the mechanism for the sudden typhoon rainstorm along Fujian coast induced by the Taiwan Strait terrain is shown.
