Trends of Summer Apparent Temperature in China metropolises for 1961-2022
摘要
Abstract
Explore the variation rules and spatial distribution characteristics of urban residents'apparent temperature and comfort in summer,metropolises with an urban population greater than 5 million in China were selected and divided into southern cities:Nanjing,Shanghai,Chengdu,Wuhan,Hangzhou,Chongqing,Guangzhou,Shenzhen and northern cities:Harbin,Shenyang,Beijing,Tianjin,Shijiazhuang,Jinan,Qingdao,Zhengzhou,Xi'an to study the spatial and temporal distribution of the summer apparent temperature(AT)and uncomfortable days for 1961-2020 based on the observed daily temperature,relative humidity and wind speed data from ground based meteorological stations,by applying the Steadman apparent temperature and comfort level classification.Results are as follows:1)In the majority of the metropolises,summer apparent temperature shows a significant increasing trend with a confidence level of over 95％.The decadal variation pattern of summer apparent temperature in northern and southern metropolises is the same,but the range of variation is higher in northern cities than that in southern cities.The change rate of apparent temperature is higher than that of air temperature on the whole.The average tendency rate of apparent temperature is 0.3 ℃/10 a,and the average tendency rate of air temperature is 0.2 ℃/10 a.The trend of apparent temperature in southern cities is more significant than that of air temperature.2)The number of uncomfortable days has increased significantly in both northern and southern metropolises.The increases is mainly concentrated on days with AT of about 33～38 ℃ in southern cities,while that in northern cities is mainly concentrated on days with AT of 28～33 ℃.3)The days with AT above 33～38 ℃ has shown a significant upward trend in both the northern and southern metropolises,with most tendency rates fluctuating around 1.2 d/10 a and showing the trend exceeding the 90％confidence level.Shanghai has the highest upward tendency rate,reaching 7.0 d/10 a.关键词
