厄尔尼诺和反厄尔尼诺与登陆斗门-厓县热带气旋的统计关系

ENSO事件是海—气相互作用的一种突出表现。它的出现会引发世界范围内的气候异常，从而导致台风活动的异常。根据1884—2000年的台风资料，采用统计的方法分析厄尔尼诺(暖事件)和反厄尔尼诺(冷事件)与登陆斗门—厓县热带气旋的关系得出：中等强度的冷、暖事件与登陆斗门—厓县热带气旋个数关系不明显：而在强或弱冷、暖事件中，冷事件影响年登陆斗门—厓县的热带气旋明显偏多。特别是在冷、暖事件影响下，登陆斗门—厓县热带气旋异常偏多年中，冷事件影响年占了64％。

Statistical Relationship Between the Number of Tropic Cyclones Landing in Doumeng-Yaxian and El Nino or La Nino Events

:As a distinct phenomenon, the ENSO event derives from the interaction of sea and atmosphere, and it will bring climate abnormal change in the world and thereby causes the abnormal activity of typhoon. In this paper, statistical methods are used to analyze the relationship underlying between the two events, El Nino (warm event) and La Nino (cold event), and the tropic cyclone landing in Doumen-Yaxian, which leads to the following conclusions that the number of tropic cyclone landing in has less relations with the medium warm or medium cold event, and that when it is in the control of stronger or infirmness cold or infirmness warm events in cold event year, the number of tropic cyclone landing in Doumen-Yaxian increases clearly. Especially in the active tropic cyclone years dominated by cold events and warm events, the cold event years occupy 64 percent of the total.
