| 摘 要： | 利用1954～2009年山西省晋南地区气候观测站平均气温和降水量资料,运用多年趋势线、Mann-Kendall突变检验、滑动t检验和小波分析等方法对晋南地区气候变化特征、突变以及周期特征进行了分析研究。结果表明：近56年来,山西晋南地区的气候有向干暖化转化的趋势。年平均气温上升趋势明显,其变化率为0.28℃/10a,尤...

| Abstract: | Based on the observed data of the mean annual temperature and precipitation from the south of Shanxi province weather stations from 1954-2009,the feature of climate change,abrupt and cyclic were analyzed with a multi-year trend line,moving t-test technique,and Mann-Kendall abrupt change test and wavelet analysis methods.The results indicate that the climate of the south of Shanxi province trends to becoming dry and warm.It was clear that the mean annual temperature had an obviously increasing tendency,the c... |
