| 摘 要： | 本文利用1966年～1983年冬季雪盖资料研究了欧亚大陆冬季(12～2月)雪盖面积同后期四川月平均气温和月降雨量之间的关系。研究表明:欧亚大陆冬季雪盖面积对四川省夏季月平均气温为负相关,同月降雨量为正相关。这种关系说明冬季雪盖面积对夏季气温和降雨量有重要的滞后影响,尤其是对川东伏旱地区的作用更为显著。还说明冬季雪盖面积大,夏季月平均气温比多年平均值偏低,月降雨量比多年平均值偏多,高温伏旱轻;相反 冬季雪盖面积小时,夏季月平均气温比多年平均值偏高,月降雨量比多年平均值偏少,高温伏旱严重。

| Abstract: | Using the Eurasian Continent winter snow Cover data from 1966 to 1983, the relations a-mong the snow cover extent and the summer temperature and rainfall in Sichuan have been investigated in this paper. The negative Correlation relationship with the Summer temperature and the positive correlation relationship with the summer rainfall have been found respectively. It is closely related in the period of mid-summer drought in the Eastern Sichuan especially, the correlation coefficient is larger than 0. 7. |
