2022年夏季武汉市三类空间气温时空变化分析
Analysis of spatiotemporal variations in air temperature among three types of spaces in Wuhan city during the summer of 2022
摘要
Abstract
Using hourly temperature observation data from 89 automatic meteorological stations in urban develop-ment areas of Wuhan city from June to August of 2022,this study analyzes the temperature variations under differ-ent weather conditions in summer among three types of spaces(urban,agricultural,ecological)in the region.It ex-plores the spatial distribution of air temperature in these three types of spaces during heatwave events and the im-pact of ecological and agricultural spaces on the air temperature in urban spaces.The results show that,for all three types of spaces,the lowest average hourly air temperatures are recorded from 05:00 to 06:00,and the highest from 14:00 to 16:00,indicating a diurnal variation trend.Heatwave events significantly increase the nighttime air tem-peratures in all three types of spaces,with the urban areas experiencing the largest increase of 4.5℃.The differ-ence in air temperatures among the three types of spaces is greatest on hot days and smallest on rainy or overcast days.Significant spatial heterogeneity in the distribution of nighttime air temperatures exists on both hot and non-hot days,forming a concentric structure of air temperatures that decrease from the central urban areas towards the outskirts.The difference in daytime air temperatures among the three types of spaces is relatively small.On both hot and non-hot days,the cooling effects of ecological and agricultural spaces on their adjacent urban spaces are most significant around sunrise and at night,with the intensity of cooling stronger on hot days than on non-hot days.关键词
