中国北方地区寒潮活动对对流层大气臭氧时空分布的影响研究

A study on the influences of the cold wave activity on the temporal-spatial distribution of tropospheric O3 over the Northern China

  • 摘要: 基于2005—2009年期间NCEP/NCAR再分析逐日温度分层资料和ECMWF提供的臭氧质量分数分层资料、2006年逐日位势高度资料,研究了寒潮发生过程对中国北方地区对流层臭氧分布的影响.其结果显示,寒潮过程中冷空气从70°N以北的源地把含有臭氧的气团沿着寒潮路径向南输送,随着寒潮的爆发,大气运动的动力输送作用将会影响我国北方高空的臭氧分布,导致对流层250hPa上的臭氧质量分数增加而700hPa臭氧质量分数降低,影响的时间长度为1~4d.同时发现,寒潮发生的季节和强度不同,对臭氧分布的影响也有所不同

     

    Abstract: Based on the NCEP/NCAR reanalyzed data of ozone mass mixing ratio and temperature data during 2005—2009 and ECMWF Geopotential Height in 2006,the influences of the cold wave activity on the tropospheric O3 over the Northern China have been studied in this paper.Firstly’ the results show that ,in upper troposphere,the high-concentration ozone air located in high latitude will be carried to the Northern China along the cold wave path;and in the middle-lower troposphere,the low-concentration ozone air will arrive to Northern China regions.Thus the cold wave activity will affect the ozone distribution of Northern China.Secondly,the cold wave can lead to ozone increase at 250hPa and decrease at 700hPa,and the influence time is 1—4d.Thirdly, with the differences of the seasons and intensity of the cold wave,the influences of the cold wave activity on the ozone distribution vary.
