中文摘要：

为了解闪电对对流层上部微量气体的贡献,利用全球水资源和气候中心（GHRC）提供的1995年4月-2006年6月的闪电卫星格点资料,以及高层大气研究卫星（UARS）上的卤素掩星试验（HALOE）1991年10月-2005年11月的观测资料,分析了全球闪电与对流层上部NO和O3体积分数的时空分布特征及其相关性.结果表明：全球闪电12、1、2月集中在南半球,6-8月集中在北半球,全球闪电的季节分布与NO、O3类似;NO体积分数在350 hPa附近达到最大,该高度的南半球NO体积分数变化范围为7×10-12～11×10-12、北半球为3× 10-12～17× 10-12;450～300 hPa,北半球夏季O3体积分数呈明显增加趋势,且同一高度上夏季的值比年平均值大25％左右,南半球夏季O3体积分数高于冬季,但差异并不大.结论进一步证明了闪电与对流层上部NO及O3的密切关系,也为研究全球气候变化提供有力证据.

英文摘要：

In order to understand the effect of lightning on the trace gases in the upper troposphere,this paper studies the spatial and temporal characteristics of NO and O3 volume fraction in the upper troposphere,the global lightning activity,and their relationships.The lightning data from April 1995 to June 2006 and the trace gases data from October 1991 to November 2005 are obtained from Global Hydrology Resource Center（GHRC） and the Halogen Occultation Experiment（HALOE） boarded on the Upper Atmosphere Research Satellite （UARS）,respectively.Results show that global lightning concentrates in Southern Hemisphere from December to next February,and in Northern Hemisphere from June to August.Global lightning activity is in agreement with NO and O3 volume fraction in seasonal variations.NO volume fraction reaches the maximum at 350 hPa.At this height,NO volume fraction is from 7 × 10-12 to 1 1× 10-12 in Southern Hemisphere,while is from 3× 10-12 to 17× 10-12 in Northern Hemisphere.At the height range from 450 to 300 hPa,O3volume fraction in Northern Hemisphere in summer increases obviously,which is about 25％ more than the annual average.Comparatively,O3 volume fraction in Southern Hemisphere in summer is bigger than that in winter,but the difference is not obvious.All the results prove that there are good relationships between the lightning and NO/O3in the upper troposphere.It provides powerful evidences on the research of global climate change.
