| 摘 要： | 利用1992—2002年的HALOE资料,选取青藏高原地区(28°~40°N,75°~105°E)的数据,分析了青藏高原地区NOX混合比的垂直分布特征,并对高原地区不同高度上NOX混合比与同纬度及同经度地区进行了比较,分析了NOX混合比与臭氧混合比纬向分布的关系,以及NOX混合比随时间的变化和O3混合比变化的关系。结果表明:青藏高原地区在300~30 hPa上夏季NOX的混合比高于冬季的混合比;夏季青藏高原地区200~30 hPa气层上NOX的混合比比同纬度其它地区高得多,100~60 hPa气层上NO2混合比比同经度其它地区也高得多;在100~30 hPa上,O3的纬向分布与NOX的纬向分布之间存在较明显的反相关关系;高原地区100 hPa附近和70~35 hPa之间夏季NOX混合比的变化与O3混合比的变化的反相关关系非常好。

| Abstract: | Using the HALOE data(from 1992 to 2002),the features of the vertical distribution of nitrogen-oxide over the Qinghai-Xizang Plateau in summer and winter have been discussed,the mixing ratio of NO_Xin different altitudes over the Qinghai-Xizang Plateau is compared with that of the same latitudes and longitudes,then the relationship of the zonal distribution of NO_Xwith O_(3)and the correlation between the time series of the mixing-ratio of NO_Xand O_(3)have been analyzed.The followed conclusions are made: From 300 to 30 hPa the mixing ratios of NO_Xover the Qinghai-Xizang Plateau in summer is higher than that of in winter;The mixing ratio of NO_(2)over the Qinghai-Xizang Plateau is much higher than that of in the same latitudes at 200~30 hPa layer,it is also higher than that of in the same longitudes at 100~60 hPa layer.There is inverse correlation between the zonal distribution of NO_Xand the zonal distribution of O_(3)from 100 to 30 hPa;In summer near 100 hPa and from 70 hPa to 35 hPa the negative correlation between the time series of mixing ratios of NO_Xand O_(3)over the Qinghai-Xizang Plateau is very evident. |
