基　　金：This work was supported by the National Natural Science Foundation of China (40075029) and Institute of Atmospheric Physics, Chinese Academy of Sciences (8 2212). We would like to thank the data providers, TOMS data processing team at Godard Flight Center, NASA, NCAR/NCEP, and Chinese Arctic Expedition 1999, National Ocean Administration of China. In addition, authors give great appreciation to Mr. Wang Wei's data collecting work in the Chinese Arctic Expedition 1999. 摘　　要：In 1999 summer, Chinese Arctic Research Expedition operated the Chukchi Sea. On Chinese icebreaker Xuelong, we made many high-resolution ozonesonds measurements. During the period from August 18 to 24, a synoptic scale observation was taken at 75°N, 160°W. Using the above data, together with TOMS total ozone and NCEP circulation data, we showed that atmospheric ozone amount experienced a high-low-high variation, with low-high-low tropopause altitude. Correlation analysis showed a close relation between the total ozone and ozone below 13 km, while the variation of the maximum concentration at about 20 km didn't show any relation to the column ozone. In 500 hPa height maps, there was also the weak-strong-weak southwesterly pattern. Therefore we suggested that the synoptic system might be responsible to a low ozone advection during this ozone variation. 关键词：ozonesonds, TOMS, tropopause, SYNOPTIC system.
