【摘要】:利用福州市1961年1月—2012年12月逐日气温观测资料,分析了福州近52年来夏季气温、高温日数、极端高温的演变特征,利用5日滑动平均气温稳定22℃的标准研究福州夏季日数变化,探讨了福州夏季及夏季最热时段气温指标的年代变化和凉夏、酷暑的分布特征;利用人体舒适度指数(CIHB)研究福州夏季最热时段气象环境对人体舒适度的影响.结果表明,夏季日数、≥35℃的高温日数、≥37℃的高温日数呈明显增加趋势,线性增长速率分别为6.6d/10a,4.5d/10a,2.6d/10a;7~8月最高气温线性增长速率为0.25℃/10a,夏季最热30,15,7d平均气温的线性增长速率分别为0.17℃/10a,0.19℃/10a,0.22℃/10a;近12年为酷暑高度集中频发期,12年中有11个酷暑年;近52年福州夏季最热时段人体舒适度呈线性下降趋势,人体的感觉是越来越闷热,甚至达到炎热.
