| 摘 要： | 利用卫星数据分析了我国全境及不同区域对流层臭氧(O3)柱含量1979—2005年全年和不同季节的长期变化趋势,及不同季节对流层O3柱含量与南方涛动指数的关系。结果表明,对流层O3柱含量在夏季有微弱的上升趋势,其他季节呈下降趋势,但总体变化趋势并不显著;在珠三角和四川盆地地区四季总体呈下降趋势;在华北地区除了冬季之外,其他季节以及全年平均均为增长趋势,最高的增长率出现在夏季,达到1.10DU/10a。南方涛动强度的变化与我国一些地区的对流层O3变化呈显著相关,但华北地区对流层O3的增长趋势与大气环流变化的关系不明显。

| 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. |
