【摘要】:利用福州市1961年1月—2012年12月逐日氣溫觀測資料,分析了福州近52年來夏季氣溫、高溫日數(shù)、極端高溫的演變特征,利用5日滑動平均氣溫穩(wěn)定22℃的標(biāo)準(zhǔn)研究福州夏季日數(shù)變化,探討了福州夏季及夏季最熱時段氣溫指標(biāo)的年代變化和涼夏、酷暑的分布特征;利用人體舒適度指數(shù)(CIHB)研究福州夏季最熱時段氣象環(huán)境對人體舒適度的影響.結(jié)果表明,夏季日數(shù)、≥35℃的高溫日數(shù)、≥37℃的高溫日數(shù)呈明顯增加趨勢,線性增長速率分別為6.6d/10a,4.5d/10a,2.6d/10a;7~8月最高氣溫線性增長速率為0.25℃/10a,夏季最熱30,15,7d平均氣溫的線性增長速率分別為0.17℃/10a,0.19℃/10a,0.22℃/10a;近12年為酷暑高度集中頻發(fā)期,12年中有11個酷暑年;近52年福州夏季最熱時段人體舒適度呈線性下降趨勢,人體的感覺是越來越悶熱,甚至達(dá)到炎熱.
[Abstract]:Based on the daily temperature observation data of Fuzhou from January 1961 to December 2012, the evolution characteristics of summer temperature, high temperature days and extreme high temperature in Fuzhou in recent 52 years are analyzed. The variation of summer days in Fuzhou was studied by using the standard of stable mean temperature of 22 鈩,
