| 摘 要： | 北极地区臭氧对北极气候和环境系统起着重要作用。研究其分布和变化有助于了解北极的气候和环境及其对全球气候系统的影响,有助于气候和环境变化的数值预报。中国北极科学探测1999在北冰洋楚可奇海域成功的进行了大气臭氧观测。通过在中国“雪龙”号破冰船甲板上（于1999年8月18-24日在75°N,160°W附近处）释放大气臭氧探空仪获得了高分辨率的大气垂直结构和臭氧分布资料,可以进行大气尺度的大气臭氧变化研究。分析大气监测资料、TOMS臭氧总量资料和NCEP大气环流资料表明,大气臭氧总量随着对流层顶的低一高一低变化呈高一低一高的变化过程。研究还表明,大气柱的臭氧总量与13公里以下的大气臭氧含量关系密切,而在约20公里处的大气臭氧浓度最大值的变化与整个气柱臭氧的关系不大。500 hPa天气形势图上一个弱一强一弱的西南天气型造成的弱臭氧平流可能是这次臭氧变化的主要原因。

| Abstract: | Arctic ozone is important to the Arctic climate and environment system. Studying the ozone distribu-tion and variation is helpful for understanding the Arctic climate and environment and their impact on theglobal system, and for numerically forecasting climate and environment change. The Chinese Arctic Re-search Expedition 1999 made an ozone observation program possible over the Chukchi Sea in the ArcticOcean. Ozone soundings on board the Chinese icebreaker "Xuelong" (at 75°N, 160°W, 18-24 August 1999)made high-resolution vertical atmospheric structure and ozone distribution data available for studyingozone variation on a synoptic scale. Analysis of the observational data, the TOMS total ozone, and NCEPcirculation, shows that the atmospheric ozone amount experienced a high-low-high variation withlow-high-low tropopause altitude. The study shows a close relationship between the total ozone and theozone below 13 km, while the variation in the maximum concentration at about 20 km does not show any relationship to the column ozone. A weak-strong-weak southwesterly pattern in the 500 hPa synoptic systemmay be responsible for a low ozone advection during this ozone variation. |
