1965—2015年武汉市气候舒适度变化分析

Variation of Climate Comfort Degree in Wuhan from 1965 to 2015

基于武汉市1965—2015年气候资料,利用气候舒适度评价方法(温湿指数、风效指数、着衣指数和综合舒适指数)对武汉市各月气候舒适度的变化进行分析.结果表明,在这50年当中,武汉市4月和10月的温湿指数、风效指数、着衣指数变化不大.而其他月份有一定的变化,但气候舒适度等级变化不显著.从综合舒适指数看,春秋季气候舒适度变化不大,多为舒适期,冬季气候舒适度有所上升,夏季气候舒适度仍然较差.1965—2015年武汉市较舒适期的平均持续时间在增加,较不舒适期平均持续时间明显减少,武汉市气候舒适度整体上有提高.其中气候舒适度的年内变化呈"M"形,武汉市是典型的春秋舒适性城市.

Based on the climate data from 1965 to 2015,the variation of climate comfort degree in Wuhan was analyzed by the way of THI,WEI,ICL and CCI.Results showed that the THI,WEI and ICL in April and October of Wuhan were better and had little change duning the 50 years.Meanwhile,other month indexs had a certain change,but no significant changes were found in the comfort level.Although CCI of the spring and summer comfort degree did not change significantly,the winter climate comfort had increased and the summer comfort was still poor.We found the mean duration times of more comfortable and comfortable period in Wuhan City had increased during the 50 years,the mean duration time of less comfortable period had reduced obviously,and the shape of the variation of climate comfort degree in a year which was like an“M”had became wider.Generally,climate comfort degree in Wuhan was improved,especially in spring and autumn.
