摘要
Abstract
This study analyzed the circulation characteristics and key factors of the Saihanba area through a comprehensive analysis of the long-term abnormal temperature and precipitation patterns.The results indicated that the temperature in the Saihanba area exhibited an increasing trend from 1962 to 2020,with higher values observed in spring,autumn,and winter,and lower values in summer.Similarly,precipitation levels were higher in spring,autumn,and winter,but lower in summer.In each season,the temperature and precipitation in the Saihanba area were influenced by different factors within the context of large-scale circulation.By identifying the most influential factors,we can draw meaningful conclusions.The Saihanba area is strongly influenced by the atmospheric circulation index.Additionally,its temperature and precipitation exhibit significant correlations with the Pacific North American Pattern(PNA)in spring,the North Atlantic Oscillation(NAO)in summer,the West Pacific Pattern(WP)in autumn,and the Plateau Monsoon Index(PMI)in winter.关键词
