This paper, using the method of the combination of 14 o ’clock relative humidity, visibility and weather phenomena , selected haze days during 1980-2012 from 13 stations of Hubei Province, and studied years of variation characteristics of haze weather in Hubei Province. The results showed that the average annual haze days showed a fluctuant rising trend in whole from 1980 to 2012, but there were many peak value and val ey value during the whole changing process; haze days of most stations showed an increasing trend, among which the stations with less than 50 d haze days had a more obvious increasing trend, and the spatial distribution of annual mean haze days had distinct inhomogeneity. Haze days of Hubei Province presented the distribution characteristics of more in autumn and winter, and less in spring and summer, in which haze days during December-January were the most, and haze days during July -August were the least. Terrain had a big impact on lo-cal haze days, piedmont leeward zones were prone to haze days, mountainous re-gions were just the opposite. The research suggested that we should combine dif-ferent situations with different stations instead of exclusively from the mean value of multiple stations when we analyze the mean change of haze days in a broader area, to investigate the overal changing trend and the reasons.
