近50年安徽省气候舒适度变化特征及区划研究

利用安徽省70个台站1961-2010年逐日平均气温、风速和相对湿度,根据气候舒适度评价模型,计算得到安徽省气候舒适度时空分布特征,在此基础上通过GIS空间插值对气候舒适度进行综合区划和评价。结果表明：安徽省气候舒适度有明显的季节变化和区域分布特征,季节上每年4-10月气候总体舒适,而11月-次年3月气候相对不舒适;空...

A Study on Variations and Comprehensive Zoning of Climate Comfort Degree in Anhui Province in the Past 50 Years

Based on data of daily average temperature,average wind velocity and average relative humidity in 70 observatories in Anhui Province from 1961 to 2010,the spatial-temporal distribution of climate comfort degree was calculated by the model of climate comfort degree index.The comprehensive zoning and evaluation was done by using of spatial interpolation techniques of Geographic Information System.The results show that the temporal and spatial distribution of climate comfort degree is significantly different in Anhui.The climatic condition is relatively comfortable from April to October in general,yet uncomfortable in wintertime mainly from November to next March;the climate comfort degree in the southern part of the region is better than in the northern part.Since the 1960s,the annual climate comfortable days have obviously increased in general under global warming,and the linear increasing trend once mutated around 1986 at 95% level;however,the annual climate uncomfortable days have obviously decreased,and the linear decreasing trend mutated around 1997 at 95% level.Comprehensive zoning shows that the best comfortable climate regions are mainly located in the southern part of Jiangnan and areas along the Yangtze River;while the northeast of Huaibei Region,Dabie Mountains and mountainous areas of South Anhui are the most uncomfortable areas in terms climate.
