摘要
Abstract
Based on the sunshine hours observation data of 6 meteorological stations in Hami , Xinjiang during the years 1961-2014, this paper investigated the trends, abnormal years, abrupt change test and influence factors of the sunshine hours of Hami in recent 54 years by the linear trend, correlation analysis and M-K abrupt change test methods. The results showed that the the spring and annual sunshine hours of Hami exhibited an increasing trend over the past 54 years, the changes of summer, autumn, and winter are relatively smooth. The abnormal low sunshine hour amount occurred in 1998, and not occurred by the abnormal high annual sunshine hour amount. The spring sunshine hours occurred abrupt change in 2004, and the summer in 1993. The increase of annual sunshine hours is strongly associated with the decrease of low cloud cover amount.关键词
