摘要:

 利用2008年塔克拉玛干沙漠腹地冬季系留气艇的探空数据,利用温差法、温差—风速法、理查逊数法3种方法,对塔克拉玛干沙漠塔中地区的大气稳定度进行了初步研究,得出以下结论:(1)大气稳定度日变化明显:夜间随着高度的升高,大气状态由稳定转变为中性继而转变为不稳定。白天受太阳辐射的影响,近地面处于不稳定状态;(2)大气稳定度随着高度上升有明显的分层现象,稳定层与不稳定层交替出现;(3)3种方法计算的结果不一致,反映出温度、风和湍流对稳定度的影响。

Abstract:

Based on the sounding date from captive boatover the hinterland ofTaklimakanDesert inwinterof2008, the atmosphere stability therewas studied elementarily using three differencemethodswhich areTemperature differencemethod,Temperature differenceW ind speedmethod andRichardson numbermethod. Results showed: (1)The diurnal change of the atmosphere stabilitywas obvious in Tazhong, atnight the state of the atmosphere changed from stability to neutral then instabilitywith the height increase, and the surface layerwas instable due to the impactof the solar radiation in daytime; (2)The atmosphere stability has significantly stratificationwith the height increase, the stable and the instable layer appeared alternately; (3)The results calculated by the above threemethodswere different, which reflected that the atmosphere stabilitywas influenced by temperature,wind and turbulence.

Key words: Taklimakan Desert, atmospheric stability, temperature, wind speed
