| 摘 要： | 基于梅雨综合指数,本文对1955—2010年江淮梅雨与梅雨期西北太平洋TC的变化关系及成因进行统计分析研究。结果表明:梅雨强弱与梅雨期TC频数存在显著的负相关,达到-0.41。同时,挑选出强梅雨年和弱梅雨年,发现强、弱梅雨异常年的TC特征差异显著,表现在:强梅雨年TC生成较少,以西、西北行为主,主要影响我国南部地区;弱梅雨年TC生成偏多,以转向路径为主,影响我国东南沿海众多省份。此外,两者通过大气环流场相互影响,梅雨期季风槽的位置与强度影响TC生成频数与源地,TC的活动又反作用于梅雨期的环流形式与水汽输送。

| Abstract: | Based on the comprehensive index of Meiyu, the relationship between Tropical Cyclone (TC) during Meiyu period in the northwestern Pacific and Meiyu in the Yangtze and Huaihe valleys from 1955 to 2010 and its causes were statistically analyzed. Results show that an obvious negative correlation -0.41 between the Meiyu intensity and TC frequency during Meiyu period was found. The obvious differences of TC features in strong and weak Meiyu years can be explained by the fact that in the strong(weak) Meiyu anamalous years, a few(more) TC genesis are available, prevailing westerly and northwesterly directions(the turning tracks), affecting mainly South China(Southeast China sea area). Besides, the atmospheric circulation attributes to the interrelationship of TC and Meiyu. The intensity index and east/west position index of monsoon are significant to TC frequency and genesis, on the other hand, the TC activity exerts great influence on the atmospheric circulation and the water vapor transportation of Meiyu. |
