摘要
采用了后向轨迹方法,利用臭氧混合比ρ3和风场资料,来探讨东亚和西太平洋地区上空Hadley环流对对流层臭氧分布的影响,文中对所研究关键点上7月份对流层高、中、低三层的轨迹进行分向统计后,计算方向概率与ρ3的相关系数,得出了东亚和西太平洋地区Hadley环流水平平流作用对臭氧分布的影响.结果表明:①青藏高原地区上空对流层低层Hadley环流水平平流作用将会使臭氧混合比减少,而对应的高层南半球Had-ley环流下沉支,其总体效果则是使臭氧增加;②在西太平洋地区上空对流层低层,北半球Hadley环流上升支其作用是使臭氧混合比减少,对应的高层南半球Hadley环流下沉支,其影响较弱;③另外,东亚季风的水平平流作用似乎和臭氧的分布也有联系,这还有待于进一步研究.
Based on analyzing the ozone mixing ratio ward trajectory method, the effect of Hadley circulation on (P3) and wind field data, and by applying the back- the distribution of tropospheric ozone over the East A- zone,while at the high - level of the corresponding southern hemisphere, its overall effect is to increase the o- zone. Secondly, at the low - level troposphere over West Pacific region, its role is to reduce the mixing ratio of o- zone and corresponding to the high- level troposphere of southern hemisphere,and its impact is weaker. What's more, the horizontal advection of the East Asian monsoon may have an effect on the ozone distribution which is worth further studying.
