Abstract:
Objective To study the impact of the high temperature and muggy weather on the people’s life and work. Methods The data of summer temperature and relative humidity (Jun-Aug) from 1971 to 2000 and that of 2006 were used and the characteristic of muggy weather and distribution in main cities, Chengdu, Guangyuan, Yibing, Suining and Dazhou in Sichuan basin were compared, the influence of the thermal environment on people comfort degree was evaluated by using temperature-humidity index. Results 177 high temperature days, 17 high temperature processes, 167 muggy weather days and 12 muggy processes were seen in 5 cities in Sichuan basin in the summer of 2006. The thermal environment of Chengdu and Dazhou mainly manifested the lighter heat, heat and lower comfort degree. At 2 p.m., the relative humidity weakened the comfort degree in Chengdu, but enhanced it in Dazhou. The duration of non-comfort degree in Dazhou was longer than that in Chengdu. Conclusion The relative humidity has a strong impact on people comfort degree and the combined use of temperature and relative humidity will be useful to evaluate the city thermal environment and people comfort degree.
