利用1900 ～2011年的海表面温度(SST)和海平面气压场资料,研究了太平洋地区海表面温度及全球大气的年代际持续性分布特征,结果表明,SST在北太平洋和西太平洋地区存在较高的年代际持续性,这些区域SST持续性平均在10年左右,最高达18年以上,低值区主要在热带中太平洋,持续性在4年以下.北太平洋的高持续性与太平洋年代际振荡(PDO)有密切联系,而热带中太平洋的低持续性主要是受到ENSO的影响；大气持续性具有明显的纬向分布特征,在高纬度地区的持续性较高,在20°S和60°N附近持续性较低.%Sea surface temperature and sea level pressure during 1900-2011 were used to study the decadal persistence distribution characteristics of the Pacific sea surface temperature and the global atmosphere.The results showed that:persistence of SST of the North Pacific and the Western Pacific is high,about 10 years up to 18 years,low value areas are mainly located in the tropical middle east Pacific,less than 4 years.High persistence of SST of the North Pacific is closely linked with PDO,and the tropical Pacific low persistent mainly due to the impact of ENSO.Persistence of global atmosphere has obvious zonal distribution characteristics.High value areas are mainly locatedin the high latitudes,the areas near 20°S and 60°N have lover persistence.
