| 摘 要： | 利用NCEP 1°×1°再分析资料、T213分析资料和常规观测资料，从水汽条件、热力条件、动力条件等方面，对2008年第6号台风“风神”路径、强度变化的原因，及其对江西的影响进行分析。结果表明，台风路径与副高的强度和位置变化密切相关，台风移动方向与风场结构中强风速的风向一致。台风在海上强度减弱主要与水汽来源不足有关，登陆后还与冷空气侵入暖中心有关。由于强度减弱且西南季风不强，造成水汽来源不足，从而导致“风神”没有给江西造成大范围暴雨天气。其中的局地强降水天气发生在台风环流高能梯度锋区，这主要是由于干侵入引发对流性不稳定造成的。

| Abstract: | Based on the NCEP 1°×1° reanalyzed data, the T213 data and the conventional observation data, the typhoon Fengshen＇s track and intensity and its influence on Jiangxi were analyzed by taking account of the water vapor, dynamic and thermal conditions, The results showed that the Fengshen＇s track was closely related to the intensity and position of subtropical high, its moving direction agreed well with the direction of maximum speed in wind field, and its intensity decreased duo to lack of sufficient moisture sources. After landing, the decrease of the Fengshen＇s intensity was related to the warm-cored structure of the invading cold air. No severe rainstorm occurred in Jiangxi duo to the intensity weakening and the lack of moisture in weak southwest monsoon. |
