摘要
该文利用1991—2020成都市西部邛崃国家气象观测站日平均气温、日最高气温、日平均风速、日平均相对湿度和日最小相对湿度,计算逐日人体舒适度指数及白天和夜间舒适度指数,并通过线性倾向估计方法分析近30 a邛崃市人体舒适度变化特征。结果表明:(1)近30 a邛崃市没有暑热和寒冷天气,人体舒适度日数舒适级别日数最多,其次是冷不舒适级别日数,热不舒适级别日数最少。(2)近30 a邛崃市年平均人体舒适度指数呈现较小的上升趋势;舒适日数集中在春季、夏季、秋季3个季节;热不舒适日数和舒适日数在21世纪初期比20世纪90年代有所增加,冷不舒适日数有所减少。(3)近30 a邛崃市白天人体舒适度指数有较明显的升高趋势,夜间人体舒适度指数变化不大。
In this paper,the daily average temperature,daily maximum temperature,daily average wind speed,daily average relative humidity and daily minimum relative humidity of the National Meteorological Observation station Qionglai,western Chengdu from 1991 to 2020 were used to calculate the daily human comfort index,day and night comfort index.The linear propensity estimation method was used to analyze the change characteristics of human comfort in Qionglai City in the past 30 years.The results show that:(1)in recent 30 years,the number of days of comfort level is the most,followed by the number of days of cold discomfort level and the number of days of hot discomfort level is the least.There is no extreme hot and cold weather in Qionglai City.(2)In recent 30 years,the annual average human comfore index in Qionglai City has shown a small upward trend.The number of comfortable days is concentrated in spring,summer and autumn.From the 1990s to the early 2000s,the number of thermal discomfort days and comfortable days increased and the number of cold and uncomfortable days decreased.(3)The human comfort index increased obviously in the daytime,but changed little at night.
