摘    要: 利用1992年9月~2005年8月的HALOE资料,对我国低纬高原地区上空平流层中NOx,O3等大气痕量气体的混合比垂直变化进行了研究,并对本区域不同高度上NOx混合比与全球同纬度进行了比较,同时对NOx随时间的演变特征,NOx的变化周期及NOx与O3的相关关系进行了分析.结果表明:①NOx,O3混合比先随高度增加,到极值时又逐渐减小;在极值高度上,各个季节NOx,O3的混合比值都是夏季最高,冬季最低;②在5 hPa以上,春季NO混合比与同纬度地区的纬圈平均相比其值更高,各个季节NO2混合比的总体趋势都要比同纬度地区低;③在100,10 hPa和1 hPa上,NOx混合比随时间变化的总体趋势是各不相同的;④NOx具有准2 a周期变化;⑤在10 hPa附近,NOx与O3存在较明显的反相关关系.

关 键 词:低纬高原地区  平流层  氮氧化物  臭氧  相关分析

Abstract:Based on the HALOE data during September 1992 to August 2005,the vertical change of NOx and O3 in the stratosphere over China’s low latitude plateau and the seasonal difference of NOx comparing with the global zonal mean values in the same latitude have been discussed,then the time evolution of NOx,the period of NOx and the correlation between NOx and O3 have been analyzed.The results show that:①the mixing ratio of NOx and O3 increase with height first,then decrease above the maximum height.At the maximum height,the mixing ratio of NOxand O3 reach its highest values in summer and lowest in winter;②at 5 hPa,the mixing ratio of NO in spring is higher than the same zonal average.the mixing ratio of NO2 in all season are almost lower than that of in the same latitudes;③at 100 hPa,10 hPa and 1 hPa,the trends of NOxare different;④the NOxvariation has QBO feature;⑤there exits an obvious inverse correlation between NOxand O3 at 10 hPa.
Keywords:low-latitude plateau  stratosphere  NOx  ozone  correlation analysis
