Taking into account the non-uniformity of the temperature sequence, the annual and seasonal temperature series over Wuhan region during 1905-2005 were established through a reasonable interpolation. The results showed that annual mean temperature and annual mean minimum temperature had showed an upward trend with rates of 0.014℃/10a and 0.026℃/10a since 1905, whereas the annual mean maximum temperature was a weak downward trend with a rate of -0.003℃/10a.All these indicated that a warming trend over Wuhan region was more visible at night, yet little during daytime, and that the annual mean maximum temperature and mean minimum temperature had showed an asymmetric trend. The annual mean temperature and the annual mean maximum temperature had two warm times, which were 1920s-1940s and 1990s up to the present. The summer and autumn temperature were higher during the first warm period, but the winter and spring were not obvious, moreover high temperature occurred in daytime. The four-season temperature was higher during the second period, the winter and spring were most obvious, but the summer was weak, moreover warm at night.
