中文摘要:

利用2008年10月11~17日的系留气艇探空资料,分析了塔中边界层O3浓度的变化特征及其与气象因子的关系。结果表明:塔中秋季边界层O3浓度均值为48.7×10^-9在边界层内中午O3浓度随高度升高几乎没有变化;深夜和清晨O3浓度从地面随高度的升高逐渐增大;傍晚O3浓度最大,随高度的升高缓慢减少,达到一定高度后变化均很小。O3浓度随高度变化明显,从1m到700m高度的O3浓度变化分为不稳定型、过渡型和稳定型。根据廓线变化方式分为深夜清晨型、中午型、傍晚型。分析表明,秋季O3浓度与温度、相对湿度、比湿、风速有关。在深夜和清晨出现逆温层,在逆温层内O3浓度较低。O3浓度与相对湿度呈负相关,02:OO和08:00的相关性最显著。在深夜和清晨比湿与O3浓度基本上是呈反相的关系。O3浓度与风速的相关性除了深夜相对较高外(R=0.699,n=33,P〈0.001),其余时间均不太明显。

英文摘要:

Using the tethersonde data from October 11 to 17, 2008, the change characteristic of the O3 and its changes with the weather factor in the hinterland of Taklimakan Desert in the boundary layer (2 km) are analyzed. The results show that the daily variation of atmospheric O3 are obvious(especially more significantly below 100 m), whose density is 48.7× 10^-9 on average in autumn. O3 concentration increases with height increased at early morning and midnight, and up to the maximum at sunset, however almost without change at noon. It decreases with height increased at sunset. The change of O3 concentration is quite little when reach to special height except noon. There is an obvious change in O3 concentration with height, change situation of O3 concentration from 1 to 700 m was divided into three types are unstable type, transitional type and stable type. According to the profile changes in the way, the concentration ofO3 profile can be divided into 3 types are night and early morning-type, noon-type, dusk-type. The analysis showed that there was relationship between the O3 concentration and temperature, relative humidity, as well as specific humidity and wind speed in the fall. The analysis of inversion layer appeare at midnight and early morning that O3 concentration is low and negative correlation with relative humidity, the correlation reach maximum at 02:00 and 08:00. The results show inverse correlation between specific humidity near to surface atmospheric boundary layer and O3 concentration, but the O3 concentration is high correlation with wind speed(R=0. 699, n=33, p〈0. 001), it is no significant at other time.
