Abstract: In order to study the law of haze climate change characteristics in 1980-2012 in Hubei Province, the author used the‘14 relative humidity, visibility, weather phenomena’method to filter out 13 sites of haze days in Hubei Province from 1980 to 2012, to study the regional climate change characteristics over the haze. The results indicated that: the average annual haze in Hubei has obvious regional spatial distribution in homogeneity, the average annual number of days of haze from 1980 to 2012 fluctuated upward trend overall, but the presence of multiple peaks and valleys throughout the change process. Haze days of most of the meteorological stations was decreased, and the haze days of stations less than 50 had more obvious growth trend, the authors noted that when analyzed the changes in a larger area, people should combine different situations of various types of stations to investigate the overall changes and the reasons, but calculated the average of multiple sites solely. The haze days in Hubei province were more in autumn and winter, less in spring and summer. And the haze days was most in December and January, least in July and August. Topography had great impact on the local haze days, haze appeared most in the foothills and appeared least in the mountains.
