摘要
本文根据长江中下游六省一市3—5月气温与降水资料,确定低温连阴雨天气过程。发现连阴雨及连晴过程所对应的热带环流及波谱特征有明显差异,热带太平洋156°E、180°剖面上总云量分布特征有显著不同,厄尔尼诺年与长江中下游连阴雨天气的关系十分密切。
In the paper, the low temperature and steadily rainy synoptic process is defined based on temperature and precipitation data. It is discovered that the tropical circulation and spectrum features in the process of steadily rainning varies significantly from that of steadily shining. The distribution of total cloud cover on the section of 156°E is obviously differents from that of 180° in the tropical Pacific. In addition ,the El Nino year has got a relationship much closer with the steadily rainning weather in the middle and lower reaches of the Changjiang River .
