1991-2019年呼和浩特市人体舒适度变化特征分析

Analysis on the Variation Characteristics of Human Comfort in Hohhot from 1991 to 2019

基于“黄金分割率”的体感温度计算及相应舒适度划分法,利用呼和浩特市1991—2019年7个气象观测站逐日数据,分析了人体舒适度等级和日数不同尺度的时空变化特征,并分析了各气象因子与体感温度间的相关关系。结果表明:呼和浩特市不同舒适度等级日数所占比例由大到小依次为严寒域日数、广义舒适域日数和酷热域日数。其中广义舒适域日数呈现南北多、中间少的分布特征,夏季最多,春季和秋季次之。影响体感温度的最主要气象因子是气温,相对湿度和降水量主要通过气温影响体感温度。

Based on the“golden ratio”somatosensory temperature calculation and the corresponding comfort classification,using the daily data from 7 meteorological observation stations in Hohhot from 1991 to 2019,the spatiotemporal variation characteristics of human comfort level and number of days at different scales were analyzed,and the correlation between various meteorological factors and somatosensory temperature was also studied.The results showed that the proportions of days with different comfort levels in Hohhot were,in descending order,days in the cold zone,days in the generalized comfort zone and days in the hot zone.Among them,the number of days in the general comfort zone presented the distribution characteristics of more in the north and south and less in the middle,with the most in summer,followed by spring and autumn.The most important meteorological factor that affected somatosensory temperature was temperature.Relative humidity and precipitation affected somatosensory temperature mainly through air temperature.
