Abstract:
Using Mann-Kendall jump test and moving t-test, the temperature change features in China in recent 55 years are analysed based on the data of monthly mean air temperature from 160 stations in 1951—2003, with a focus on the analysis of the regional and seasonal features of abrupt temperature change. It is found that (1) since the 1950′s the cooling regions became smaller and the trend weaker;(2)the sudden changes are observed in Northeast China and North China in the last 1980′s;(3)the jump change in winter was earlier than the other seasons in the same area.
