| 摘 要： | 每年初夏长江流域雨期的连续阴雨称为梅雨,西太平洋上靠近热带地区的强气旋称为热带气旋(我国习惯称为台风),这2种天气现象都属于大尺度范围内大气环流引发的.本文采用统计学方法分析了1946～2000年55 a间2个气候系统的相互关系,并计算2个系统指数的相关系数.结果表明:梅雨与台风呈负相关关系,即当年如果梅雨偏多,梅雨期偏长,则台风偏少.反之,台风次数多的年份,梅雨量较小,梅雨期短.春季或梅雨前台风次数较多的年份,入梅时间会晚一些,梅雨量少,梅雨期短;梅雨量较多的年份出梅后的台风较少,尤其是秋季台风明显减少.

| Abstract: | Meiyu and Tropic cyclone are both weather system that are related to large scale atmospheric circulation.In this paper,using statistics method to analyze the relationship between Meiyu and Tropic cyclone and figure out the correlation coefficients between their exponents about 55 years from 1946 to 2000.As the result,there are the negative correlation between typhoon and Meiyu.That is the more quantities in Meiyu,the longer of the Meiyou-period,so the less of the typhoon.On the other hand,the more numbers o... |
