摘要
应用统计学方法,分析了欧亚大陆雪盖与四川盆地夏季气温的关系。结果表明:前期雪盖面积异常对四川盆地夏季冷暖有长期稳定的影响,而冬春季最为显著;欧亚大陆雪盖是四川夏季长期天气过程的主要影响因子,在四川长期天气业务预报中具有明确的应用价值。
The relationship between the Eurasian snowcover and the summer temperature in Sichuan is analyzed by the statistical method.The results show that the abnormal snowcover area in Eurasia in the earlier stage play an important role in the summer temperature in Sichuan,particularly the winter snowcover.The eurasian snowcover is one of the main elements in summer long term wheather process in Sichuan,which has a practical value in the long term weather forecast in Sichuan.
