      摘要: 利用衛(wèi)星數(shù)據(jù)分析了我國(guó)全境及不同區(qū)域?qū)α鲗映粞酰∣3)柱含量1979-2005年全年和不同季節(jié)的長(zhǎng)期變化趨勢(shì),及不同季節(jié)對(duì)流層O3柱含量與南方濤動(dòng)指數(shù)的關(guān)系。結(jié)果表明,對(duì)流層O3柱含量在夏季有微弱的上升趨勢(shì),其他季節(jié)呈下降趨勢(shì),但總體變化趨勢(shì)并不顯著;在珠三角和四川盆地地區(qū)四季總體呈下降趨勢(shì);在華北地區(qū)除了冬季之外,其他季節(jié)以及全年平均均為增長(zhǎng)趨勢(shì),最高的增長(zhǎng)率出現(xiàn)在夏季,達(dá)到1.10 DU/10a。南方濤動(dòng)強(qiáng)度的變化與我國(guó)一些地區(qū)的對(duì)流層O3變化呈顯著相關(guān),但華北地區(qū)對(duì)流層O3的增長(zhǎng)趨勢(shì)與大氣環(huán)流變化的關(guān)系不明顯。

      Abstract: Long-term trends of yearly and seasonal averages of tropospheric ozone over the whole country and some important regions of China during 1979-2005 were analyzed, based on the tropospheric ozone residue (TOR) data retrieved from satellite measurements. The relationship between TOR and the Southern Oscillation Index (SOI) was studied. The results show that, over the whole country, there was a slight increase of TOR in summer and a decrease in other seasons, while the overall trend for the whole period was insignificant. There were decreasing trends of TOR over the Pearl River Delta and the Sichuan Basin. Significant increasing trends of TOR were found over the North China Plain for all seasons except winter, with a maximum rate of 1.10 DU/10a for summer. There were significant correlations between TOR and SOI for some Chinese regions but not for the North China Plain, suggesting that the observed increasing trend of TOR over the North China Plain may not be linked with changes in atmospheric circulations.

      Key words: China, tropospheric ozone, change trend, SOI
