快速移动的0510号热带风暴"珊瑚"路径及对深圳降水影响的分析

从天气形势、雷达回波和卫星云图特征对2005年第10号热带风暴“珊瑚”的移动路径和对深圳降水的影响进行了详细的分析．结果表明：副热带高压的演变，对热带气旋的移动路径尤其是路径的转向影响很大，副高的增强、减弱是热带气旋发生转向的重要条件；螺旋云带的变化通常能表明热带气旋未来的移动及其强度变化，眉状云带是热带气旋北上的重要特征云系；“珊瑚”在登陆前后西侧云系迅速减弱，以及登陆后加速北上，深圳没有转吹南风，是导致深圳没有出现暴雨的主要原因．

An analysis on the fast-moving 0510 tropical storm Sanvu's path and precipitation influences to Shenzhen

A detailed analysis is carried out on the path and the precipitation in Shenzhen of tropical cyclone Sanvu in 2005 based on weather patterns,radar images and satellite images.The result shows that:the evolvement of subtropical high can strongly affect the path,particularly the turning of the path,of a subtropical cyclone.The strengthening or weakening of a subtropical high is a major condition for the turning of a tropical cyclone.Usually,the change of spiral cloud bands can indicate the change of the moving direction and the strength of a tropical cyclone.The eyebrow-shaped cloud bands are important characteristics of a northwards-moving tropical cyclone.The tropical cyclone Sanvu did not bring a rainstorm to Shenzhen due to:a) the western cloud system weakened rapidly around the landing of Sanvu,and b) Sanvu moved northwards after landing thus Shenzhen's wind direction did not change to south.
