摘要
利用青海省同德县气象局观测的1961—2010年总云量资料,采用线性趋势、M-K突变检验等方法,分析了近50年来该地阴、晴天气日数的变化规律。结果表明,近50年同德地区年平均晴天日数呈显著的增加趋势,四季平均晴天日数均呈不显著增加趋势。阴天日数随年份增减不明显,秋季阴天日数呈显著减少趋势,春季阴天日数增多趋势显著,夏季和冬季的阴天日数呈不显著增多趋势。昙天日数随年份呈显著减少趋势,秋季昙天日数呈不显著增多趋势,春季、夏季和冬季的昙天日数均呈显著减少趋势。晴天日数在1985年发生了由少到多的突变,阴天和昙天日数均未发生突变。
Based on the total cloud cover data observed by the Tongde County Meteorological Bureau in Qinghai Province from 1961 to 2010,the variation law of the number of cloudy and sunny days in the past 50 years was analyzed by linear trend and M-K mutation test and other methods. The results showed that the annual average number of sunny days in Tongde area had increased significantly in the past 50 years,and the average number of sunny days in the four seasons had not increased significantly. The number of cloudy days increased significantly with the year,and the number of cloudy days in autumn decreased significantly. The number of cloudy days in spring increased significantly,and the number of cloudy days in summer and winter showed no significant increase. The number of tan days was significantly decreased with the year,and the number of tan days in autumn showed no significant increase trend,and the number of tan days in spring,summer and winter showed significant decrease. The number of sunny days occurred from less to more mutations in 1985,the number of cloudy days and tan days were no mutations.
