Establishment and Effectiveness Testing of Summer Comfortability Model in Jiangsu
Based on the analysis of the measured data at 24 stations in Jiangsu Province from 2000 to 2021,the principal components of the impact of meteorological factors on comfortability are extracted.On the basis of CIHB(Comfort Index of Human Body),a summer high temperature comfortability index model with the daily solar radiation,the daily temperature range and the continuous days of high temperature as the leading factors is established by using nonlinear regression method.The comfortability index is graded and categorized,and its spatio-temporal evolution characteristics are analyzed.The results show that meteorological factors have four main principal components on comfortability,which are related to temperature,sunlight and radiation,humidity,and wind speed;The coefficient of determination R2 of the comfortability model for each station is above 0.800,indicating a good fitting effect;The comfortability index has shown a fluctuating upward trend from 2000 to 2021.The summer comfortability index in the areas along the Yangtze River and in Sunan is the highest.The comfortability index in the areas between the Yangtze River and Huai River ranks the second.The relatively comfortable zone for the summer lies in the areas to the north of Huai River.
