东亚地区大气环流活动与臭氧总量变化关系分析*

An analysis on the relationship between atmospheric circulation and the total ozone changes in East Asia

  • 摘要: 利用欧洲中心(ECMWF)再分析资料及NOAA的南方涛动指数(SOI)等数据,分析了1984—2014年北太平洋涛动指数(NPOI)、南方涛动指数的变化趋势,以及各指数与东亚地区臭氧总量变化之间的相关关系.结果表明:①北太平洋涛动指数近31a呈现下降趋势,北太平洋涛动对东亚地区臭氧总量的变化有一定的影响.②南方涛动则主要是通过2个事件,即厄尔尼诺事件和拉尼娜事件来影响副高的强度,进而使得东亚地区臭氧总量发生变化.

     

    Abstract: Applying the reanalysis data from ECMWF data-set and the data of Southern Oscillation Index (SOI) from NOAA,the tendency of the North Pacific Oscillation Index (NPOI),the temporal-spatial distribution of the North Pacific Oscillation and Southern Oscillation has been analyzed,and their influence on the total column ozone(TCO) over East Asia has been studied in this paper.The results show that firstly,the North Pacific Oscillation index shows a downward trend in recent 31a,and North Pacific Oscillation have a certain impact on the change in the total amount of ozone in East Asia.Secondly,the Southern Oscillation also has some relationship with the TCO change,which has something to do with the strength of the Subtropical High and the El Nino/La Nina event.
