摘要

Abstract

Based on the average data of daily air temperature which is below 0℃ during the periods from 1975 to 2009, the winter negative accumulated temperature was calculated. Using the trend analysis and wavelet analysis method, analyzes the spatio-temporal variation of winter negative accumulated temperature. The results show that winter negative accumulated temperature rises from southeast to northwest with the increasing altitude and elevation. We can see an obvious interannual variability of negative accumulated temperature, during recent 35 years the negative accumulated temperature drops on the whole. The negative accumulated temperature mainly shows an interannual oscillation periods of 4 years and 8 years.
