摘　　要：本文主要用卫星云图、舟山713雷达探测资料分析“威马逊”台风的结构特点,以及用MICAPS系统下发的t213物理量资料诊断分析“威马逊”台风对流层各层的物理量分布,发现在台风东北象限降水条件最好,西南象限最差。并初步分析了其原因是由于输入云带的影响。用舟山测风站资料计算物理量,分析台风边界层的物理量特征。最后分析了台风周围大风的分布情况,用梯度风和经验风公式拟合测站风速,并分析了拟合的误差情况。The satellite images and echo data of radar 713 in Zhoushan are analyzed to find the characteristics of typhoon Ramasun's structure.And the physical elements from the MICAPS system are studied to analyze the physical element distribution of all levels around the typhoon.The results show that the condition to rain is the best in the north-east part of the typhoon and the weakest in the south-west part.And the reason is the inflow cloud zone.The wind in Zhoushan is calculated to get physical elements to study the boundary of the typhoon.At last,the wind distribution around the typhoon is analyzed.
