摘要: 根据1951—2005年鞍山逐月气温资料,采用线性增长率、小波分析与滑动平均等方法对鞍山冬季气温进行分析。结果表明:近55 a来鞍山冬季气温呈明显上升趋势;冬季平均气温变化具有明显的阶段性和突变性特征,存在158、a和5 a的主要周期。

Abstract: Based on the monthly average air temperature data from 1951 to 2005 in Anshan,winter air temperature was analyzed with linear trend analysis and wavelet analysis as well as moving average methods.The results show that winter air temperature in Anshan has an obvious ascending tendency from 1951 to 2005.The changes of winter air temperature are abrupt and periodic characteristics.The main periods of winter air temperature are about 15 a,8 a and 5 a.
