| 摘 要： | 基于合肥市1956～2005年的气象观测资料,利用滑动t-检验法、Yamamoto法和Mann-Kendall法对合肥市逐年平均气温的突变特征进行比较分析;利用滑动t-检验法、Yamamoto法和滑动平均法对逐年降水量的突变特征进行比较分析.结果表明:合肥年平均气温在1986～1988年和1993年附近发生了突变,年降水量在1968年附近发生了突变.

| Abstract: | Based on the annual temperature and precipitation from 1971 to 2000 of Hefei,the characteristics of temperature was analyzed with moving t-test,Yamamoto method and Mann-Kendall method and the characteristics of precipitation was analyzed with moving t-test,Yamamoto method and moving-average method.The jumping point of temperature happened during 1986～1988 as well as in 1993 and the jumping point of precipitation was in 1968. |
