本文基于亞洲中高緯地區(qū)逐日降水觀測資料和CMIP6中12個全球模式資料,采用泰勒圖等方法,系統(tǒng)評估CMIP6模式對該地區(qū)極端降水的模擬能力,并與CMIP5結(jié)果進(jìn)行對比。結(jié)果表明,相較于CMIP5模式,CMIP6模式能夠更好地模擬極端降水指數(shù)氣候平均態(tài)以及趨勢變化特征,與觀測相關(guān)系數(shù)更高。多模式集合平均在模擬極端降水方面普遍優(yōu)于單個模式。為進(jìn)一步評估單個模型的性能,與CMIP5中的舊版本模式進(jìn)行了兩兩比較。盡管針對不同的模式和評估指標(biāo)結(jié)果存在一些差異,但大多數(shù)新版本模式模擬極端降水能力較CMIP5有所增強(qiáng)。
