摘　　要：利用客观再分析CSFR资料、最佳路径(Best track)资料、KALPANA-1红外卫星云图和探空站资料等,对2010年5月30日～6月7日发生在阿拉伯海上的热带风暴"PHET"进行了研究;分析了热带风暴的移动路径,强度变化和大尺度环流形势,根据卫星云图的特征,将其演变过程划分为发展阶段、成熟阶段和消亡阶段。对成熟阶段风暴的水平和垂直结构进行了分析,发现垂直方向对流旺盛,各物理量在风暴中心周围分布不对称,"暖心"结构明显。In this paper, the evolutionary process and spatial structure of the tropical storm ＂PHET＂ o-ver the Arabian Sea from 30 May to 7 June, 2010 were investigated by using the available observational data, including CFSR （Climate Forecast System Reanalysis） data, tropical cyclone best track data, KAL PANA-1 infrared satellite imagery and sounding data at station of 41256. Firstly, the moving track and intensity change of this tropical storm were examined. Secondly, the whole life of ＂PHET＂ was divided into three stages： developing, mature and dissipation stages based on the satellite imagery. Thirdly, the horizontal and vertical structures of this storm ＂PHET＂ were analyzed. The results showed that vertical convection was strong and physical variables had asymmetric structure around the cyclone center. Also, a ＂warm core＂ structure of this tropical storm was found.
