| Abstract: | In this paper,the SSA method is used to analyze the monthly mean temperature in Harbin nearly hundred years. The results show that temperature of Harbin is increasing trend in century-scale. In this background, increasing process has apparent decadal-scale variety： there is a period of temperature increasing from 1909 to 1955, slender decreasing from 1956 to 1969, then outstanding temperature increasing is followed after 1970. Moreover, there are 2.315 and 4.06 yearly cycle in annual-scale and 8.33 monthly cycle in monthly-scale. |
