| Abstract: | Using the sunshine hour data during the period of 1961~ 2000, we indicated that the decreasing trends during the four seasons were different. The yearly decreasing rate was 22h per year,and these trends are still getting slowly.By the abrupt change detecting with Mann-Kendall,the results showed that,the yearly and seasonal sunshine hours abruptly change in 1982. |
