中文摘要：

利用ECMWF提供的1979—2013年臭氧与位势高度资料,采用3种诊断分析方法,探讨了东亚地区臭氧与东亚冬季风的关系,得到了以下结论：（1）Iwin与东亚各等压面高度上的臭氧以正相关关系为主,其中与50、100 h Pa臭氧的正相关区域最明显;（2）东亚50、100 h Pa臭氧与位势高度的变化区域总体来看较为一致,即当中纬度的臭氧增加时,中纬度的位势高度场降低,东亚大槽加强,冬季风偏强,反之亦然;（3）合成差值分析的结果表明,当EAWM偏强时,臭氧的正差值中心从30 h Pa至100 h Pa有由北向南移动的趋势.

英文摘要：

Based on the ozone and geopotential height data during 1979--2013 from ECMWF,by using three diagnostic analysis methods, the paper has analyzed the relationship between the ozone change and the winter monsoon in East Asia.The results show that firstly, there is a positive correlation between /win and the ozone a- mount on different isobaric surface over East Asian, especially on 50 and 100 hPa ; Secondly, overall, the ozone a- mount on 50 and 100 hPa is more consistent with the change of geopotential height field over East Asia, namely, when the ozone increases on mid-latitude, geopotential height decreases, meanwhile East Asian trough deepens and the winter monsoon becomes stronger, and vice versa;Finally, synthetic analysis shows that when EAWM becomes stronger,there is a moving trend from north to south in positive difference center from 30 hPa to 100 hPa.
