摘要
对影响浙江省热带气旋的风雨进行了区划,同时还对其带来的暴雨类型进行了分类。研究表明,浙江可划分为5个风雨影响区,东南沿海区是热带气旋风雨严重影响区,浙北沿海区为大风严重影响、暴雨较严重影响区,浙北内陆区为风雨影响较严重区,浙南区以暴雨严重影响为主,浙西区风雨影响均较轻;不同路径的热带气旋带来的暴雨空间分布也可划分为5型,其中Ⅰ型和Ⅱ型降水强度最强,其典型移动路径为福州以北至象山港以南之间登陆台风。本文的热带气旋风雨影响区划较为客观地反映了所有影响浙江热带气旋的风雨概况,但在业务应用中需根据具体情况作相应调整。
The wind and precipitation distribution caused by impacting Zhejiang province tropical cyclones have been compartmentalized, so have the heavy rainstorm types. The results suggest that： There can be compartmentalized five gale and heavy rainstorm impacting sections in Zhejiang province. They are southeastern coastal area as tropical cyclone gale and heavy rainstorm severe impacting section,northern coastal area as gale severe impacting and heavy rainstorm relatively severe section, northern inner area as gale and heavy rainstorm relatively severe impacting section, southern area as heavy rainstorm severe impacting section and western area as gale and heavy rainstorm gentle impacting sections. Five different track tropical cyclones cause different heavy rainstorm distributions. The first and second type track tropical cyclones result in the strongest precipitation. The typical are typhoons which land between FuZhou and XiangShan coastal areas. The above tropical cyclone gale and heavy rainstorm impact compartmentalization impersonally reflects all the impacting Zhejiang tropical cyclone wind and precipitation distribution, but should be properly adjusted in operational application.
