Abstract

Abstract:

691 sites with complete statistics in eastern China are selected, of which the hot days, cold days and comfortable days of each year from 1971 to 2010 are added up. The Temperature-Humidity Index (THI) is calculated to evaluate the changes in climate comfort of the monsoon region in eastern China for recent 40 years. The trend of climate comfort change at the end of the 21st century is predicted through the comparison and analysis of the future scenario meteorological data. The results show that between 1971 and 2010, the monsoon region in eastern China is warming to some extent. The climate sensitivity of northeast and south China is higher than that of other regions. The climate sensitivity of coastal area is higher than that of inland, and the northeast region has a higher response to the climate change.

Key words: climate change, climate comfort, temperature-humidity index (THI), climate in the future

摘要：

选取中国东部691个数据记录较完整的站点, 统计各站点1971—2010年间每年每季的热日、冷日和舒适日天数, 利用温湿指数(THI), 评价中国东部季风区近40年的舒适度变化, 并结合未来情景下气象数据的比较和分析, 展望21世纪末中国东部地区的舒适度变化趋势。结果表明, 1971—2010年间, 中国东部季风区在一定程度上变暖, 东北和华南的气候敏感度高于其他地区, 沿海的气候敏感度高于内陆, 东北地区对气候变化的响应程度较高。

关键词: 气候变化, 气候舒适度, 温湿指数(THI), 未来气候情景
