| 摘 要： | 根据美国国家环境预测中心(NCEP)的温度资料,以近年来在我国华东登陆或近海转向的台风为例,对台风中心附近的异常增温与未来移动方向进行诊断分析。结果发现:中、高层台风中心附近的异常增温对台风未来的移动趋势有着很好的指示作用,尤其是对台风的移动方向突然改变具有预报意义,强增温区及脊(轴)线方向预示着台风未来的移动方向。由此得出了一条台风路径预报的新途径。

| Abstract: | NCEP reanalysis data are used in this paper to diagnose the movement direction of typhoon that landfall on the east China or off-ocean in recent years, and the temperature information is used to analyze the relationship between the abnormal temperature increase around the typhoon center and the movement direction of the typhoon in future. The result shows that the abnormal temperature increase near the center of typhoon at high and middle layers is related to the tendency of movement in future. The stronger temperature increase area and the orient of ridge (axis) line indicate the direction of the typhoon shift towards in future. Thus a new way of prediction of movement is given. |
