| 摘 要： | 通过对1949～1993年共计29个穿越雷州半岛台风及热带风暴特性变化进行的分析，得出:台风及热带风暴强度（Vmax）一般在登陆前6小时开始明显减弱；台风过岛后强度平均下降24%，热带风暴强度平均下降33%。热带风暴8级大风圈范围的缩小亦较台风为大；半岛对台风和热带风暴移向的影响，台风受影响较早；不论对台风或热带风暴，穿岛前、后均未出现路径明显南折现象。

| Abstract: | The characteristic variations of 29 typhoons and tropical storms crossing Leizhou Peninsula in years 1949 to 1993 have been analyzed. The results show that: the intensities of typhoon and tropical storms begin decreasing obviously at 6 hours before landing; the shrink of the gale area of the tropical storms is more than that of the typhoons; the influences of Leizhou Peninsula on the moving directions of typoons are earlier than those of tropical storms; but no tropical cyclone turns southward obviously before and after crossing the peninsula. |
