| 摘 要： | 通过对0903号台风“莲花”在登陆福建晋江并沿着海岸线北上过程中的沿海自动站逐时实况风场资料的分析，研究了该台风的风结构状况，得到以下结论：（1）台风近中心最大风速预报值比实测风速偏小，台风7级风半径则比实际的偏大．（2）实测2min平均风速最大值（Vmax）总体上呈减弱趋势，与时间（t）的回归方程式为：Vmax=28．9—0．61t（n=16，r=0．78，r005=0．50）．（3）台风最大风速半径（R）呈逐渐扩大的趋势，与时间（t）的回归方程式为：R=28．28—4．98t＋0．67t。（n=16，r=0．95,r0.05=0．50）．（4）台风最大风速区位于台风后部．认识台风风结构，有助于不断地提高预报的准确性．

| Abstract: | Due to the lack of real-time observation data when typhoon is in the sea and the influence of landscape on typhoon after it lands,analysis of the overall inner wind structure of typhoon has always been difficult to conduct.However,as for those typhoons moving along the coast,wind structure analysis is possible as the effect of landscape on them is little and hourly updated data are available from coastal areas automatic stations.Through analyzing the hourly data from coastal automatic stations after typhoon... |
