近37年成都地区基于温湿指数的气候舒适度变化特征分析

本文利用成都地区14个区(市)县国家级地面气象观测站1980~2016年的日平均气温、日平均相对湿度数据,采用温湿指数对成都地区气候舒适度进行评价分析,结果表明:成都地区4月和10月为非常舒适月份,无极度不舒适月份,春季和秋季为非常舒适季节,夏季为不舒适季节,冬季为较不舒适季节,近37年气候舒适度总体变好。相比,成都西北部、中部和蒲江县的气候舒适度较好。气候舒适度突变多发生在2009~2013年,冬季的突变发生在1984年,冬季气候舒适度向好转向的特征非常明显。

A Study on the Characteristics of Climate Comfort Degree in Chengdu Area over the Past 37 Years Based on Temperature Humidity Index

Choosed the daily average temperature and daily relative humidity data of 14 counties in 1980-2016 years in Chengdu area,based on Temperature Humidity Index (THI),this paper tries to analyze and evaluate Climate comfort degree in Chengdu,the results show that:April and October are very comfortable months,no extreme uncomfortable months,spring and autumn are very comfortable seasons,summer is uncomfortable season,winter is relatively uncomfortable season,the climate comfort has improved in the past 37 years.In comparison,the climate comfort of northwest,central of Chengdu and Pujiang county is better.The abrupt change of climate comfort mostly occurred in the period of 2009-2013.The abrupt change of winter occurred in 1984.In winter,the climate comfort tends to improve obviously.
