Abstract: In order to reveal the climatic characteristics of various scopes and different intensities of haze weather, and the effects of climate change and its associated meteorological elements variation on haze, the spatial and temporal features and variation trend of the haze days in various scopes and different intensities were studied by using the haze observation data of 108 stations in Shanxi in 1980-2012. And a correlation analysis between the varieties of the haze weather and meteorological conditions of wind, precipitation and average relative humidity was accomplished by employing the statistical method. The results showed that: (1) different intensity of haze occurred more in basins and the south than in hills and the north, the high center of which had a distribution pattern of northeast to southwest, and with rising altitude, the frequency of haze days gradually diminished; the slight and mild haze weather appeared most frequently in Taiyuan Basin and Linyun Basin, however, the moderate and severe haze appeared most frequently in Linyun Basin and Changzhi Basin; Houma in Linyun Basin was the center of haze days in the province; (2) autumn and winter were the seasons for haze weather with regional and moderate to strong intensity, especially December and January were the months with regional and wide-ranging haze weather, while November was the month with moderate and strong intensity haze; there were less haze days because of the strong wind in spring and more precipitation in summer; (3) the slight, mild, moderate and severe haze days were increasing respectively at a rate of 48 d/10 a, 15 d/10 a, 3 /10 a and 3 d/10 a, while the small-ranging, regional and wide-ranging haze days rose at a rate of 26 d/10 a, 46 d/10 a, and 1.88 d/10 a. In 1995 and 2003, regional and wide-ranging haze days began to increase; (4) when the wind was lighter than 3 m/s, the wind force had a positive correlation with haze weather, and the correlation coefficient was up to 0.807; but when the wind was stronger than 5 m/s, the correlation coefficient turned to be negative, which was -0.815; (5) annual precipitation days and days of daily average humidity ≥ 80% had obvious effect on the amount variation of the annual haze days, especially the annual days of regional or large range of precipitation.
