Abstract

Abstract: This study used meteorological station observation data and NCEP reanalysis data to analyze the characteristics of urban thermal environment and atmospheric circulation associated with an extreme heatwave event in the Zhengzhou Metropolitan Area from June 15 to 26,2022.Results showed that approximately 65% of meteorological stations in the Zhengzhou Metropolitan Area experienced 12 consecutive days of extreme high temperatures.On June 24,the peak of the heatwave,96% of meteorological stations recorded daily maximum temperatures exceeding 40 ℃,with several stations exceeding 45 ℃.This event was primarily influenced by a continental high-pressure system with an upper-level anticyclone,forming a structure with upper-level divergence and lower-level convergence,which supported the maintenance of a low-level warm low-pressure system,leading to the occurrence,development,and prolonged persistence of the heatwave.Significant urban heat island (UHI) effects were observed in all major cities within the Zhengzhou Metropolitan Area,greater UHI intensity at nighttime than daytime.The UHI intensity was correlated with the size of city,with Zhengzhou exhibiting significantly stronger UHI effects than other cities,reaching a nighttime UHI intensity up to 2.7 ℃.Under the combined effects of the heatwave and urban heat island,daytime human thermal stress duration was significantly extended in densely populated regions in the Zhengzhou Metropolitan Area.

Key words: Continental high-pressure system, Human thermal stress, Urban heat island effect, Human comfort index
