东亚季风及台风过程与臭氧含量变化的关系分析

文中用2001~2015年东亚区域的气压场和对流层顶臭氧含量的资料,选用并计算了最能代表东亚地区季风活动的两种指数,应用统计分析和个例分析的方法,对东亚地域内季风运动及台风过程与臭氧浓度变化的相关性进行了分析。得到如下结论:东亚的夏季风强度指数SMC与对流层顶臭氧含量两者在40°~50°N的高纬度地区有明显的正相关关系,赤道附近存在着负相关区。东亚IWT冬季风指数与对流层顶臭氧含量在南海—西北太平洋的海域有很好的正相关。在对流层上层受台风中心强上升气流影响最频繁的地区臭氧浓度低,而受到台风外围下沉气流影响最多的地区臭氧浓度高。 

Analysis of the Relationship between East Asian Monsoon and Typhoon Process of Ozone Levels

This article observations of atmospheric pressure and tropospheric ozone concentrations in East Asia during 2001-2015 were used, the two indices that best represent the activity of East Asian monsoon are selected and calculated, applicated the statistical analysis and case study methods, East Asia monsoon and typhoon preocess in the relationship between ozone levels were discussed.Following conclusions: There is a positive correlation between the SMC summer monsoon index and the tropospheric ozone concentration in the 40 o N to 50 o N, and a negative correlation with the Equator.There is a positive correlation between the IWT winter monsoon index and the tropospheric ozone in the the South China Sea to western Pacific.In areas affected by the strong rise in the typhoon center airstream most frequent low ozone concentration, ozone concentration is high in areas most affected by the subsidence air flow from typhoons.
