摘　　要：利用福鼎市地面观测站、区域自动站、雷达等常规资料,分析了201808号台风“玛莉亚”对福鼎市影响情况和物理量场诊断分析,为今后在福鼎南边登陆的台风提供大风和雨量预报参考。结果表明:201808号台风“玛莉亚”具有增强快、强度强、移速快、路径稳定特点,在福鼎市南边连江县登陆,给该市带来严重的风雨影响,各乡镇均出现暴雨到大暴雨,台山岛出现17级阵风;东南急流为福鼎市强降水提供了良好的水汽和动力条件;受台风外围螺旋雨带影响,强对流回波不断经过福鼎市上空,有明显的列车效应,降水效率高;地面辐合线发展和维持,触发强对流,强降水主要集中在喇叭口地形和迎风坡。This paper briefly analyzed the impact of No. 201808 Typhoon“Maria”on Fuding City and the diagnostic analysis of the physical quantity field by using the conventional data of Fuding City’s ground observation station, regional automatic station, radar, etc., to provide a reference for forecasting strong wind and rainfall for typhoons landing in the south of Fuding in the future. The results showed that the 201808typhoon“Maria” has the characteristics of fast enhancement, strong intensity, fast moving speed, and stable path. It landed in Lianjiang County, south of Fuding City, bringing serious wind and rain effects to Fuding City.Rainstorms to torrential rains occurred in all villages and towns, and 17 level gusts occurred in Taishan Island;The southeast jet provided good water vapor and dynamic conditions for the heavy rainfall in Fuding;Affected by the spiral rain belt around the typhoon, the strong convective echo continuously passes over Fuding City, with obvious train effect and high precipitation efficiency. The development and maintenance of the ground convergence line triggered strong convection, and the heavy precipitation was mainly concentrated in the trumpet shaped terrain and windward slope.
