| 摘 要： | 1999年夏季,中国首次组织北极地区科学考察.分析此次考察中楚克奇海海域上空获得的大气结构和臭氧探空资料,结合臭氧总量观测光谱仪(TOMS)臭氧总量和NCEP大气环流资料,指出:考察期间楚克奇海海域上空臭氧总量与13 km以下臭氧含量关系密切,而在20 km附近最大臭氧浓度处的臭氧变化与大气臭氧总量关系较差,表明整层臭氧总量的变化主要受低层大气臭氧变化的影响.大气臭氧总量呈高-低-高变化,对流层顶高度呈低-高-低变化,分析500hPa高度场表明:考察期间的天气系统可能是造成局地臭氧变化的主要原因.

| Abstract: | Chinese first scientific research expedition was carried out in the summer of 1999. Analysis on the observation data, TOMS total ozone, and NCEP circulation shows a close relationship between total ozone and ozone below 13 km over the Chukchi Sea, while the variation in the maximum concentration at about 20 km does not show any relation to the TOMS total ozone. Results show that the total ozone variation is mainly dependent on the lower ozone variation. The atmospheric ozone amount experienced a high-low-high variation, with low-high-low tropopause altitude in the observation. The synoptic system in 500 hPa maybe responsible to the local ozone variation. |
