Abstract：Using hourly observational data from weather stations and ERA5 reanalysis dataset in 2019-2023,employing climate comfort index and aggressive meteorological index(AMI)for health,the distribution characteristics of climatic health preservation resource in Zhejiang province are analyzed.Re-sults show that annual mean number of hours of climate with no thermal stress in Zhejiang province is about 4176.1 h,while number of hours of climate with significant heat stress and significant cold stress in Zhejiang province are 856.1 h and 35.3 h,respectively.In terms of spatial distribution,the occur-rence frequency of climate with no thermal stress is higher in the south and is lower in the north,higher in the coastal area and lower in the inland area,higher in the mountainous area and lower in the plain area.Number of hours of climate with no thermal stress in October and May are 584.1 h and 536.6 h,respec-tively,which are considered to be the most physically comfortable months for human body.Annual mean cumulative number of days of moderately strong aggressive weather for health(AMI>60)in Zhejiang province is 86.0 d,whereas number of days of highly strong aggressive weather for health(AMI>80)is 32.6 d.Under the effect of ocean climate,the AMI is relatively small and number of days of aggressive weather for health is relatively fewer in coastal area in the east Zhejiang province.Comprehensive analysis of both climate comfort index(seeking benefits)and aggressive meteorological index for health(avoiding harms)shows that there are abundant climatic health preservation resource in Zhejiang province,and the coastal area in the south Zhejiang province is the most suitable area to conduct climatic health preserva-tion activities.
