| 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. |
