| 摘 要： | 本文利用1986年中美联合青藏高原大气科学实验资料,对拉萨地区所存在的逆温现象尤其是边界层内存在的逆温进行了分析,试用耗散结构理论修正Tennekes等提出的数学模式建立了高原边界层内的混合层模式。 分析表明,拉萨地区白天仍有逆温存在。高原上的混合层具有比湿较海洋上不稳定和层底较高的特点。混合层的形成与逆温有关,逆温是混合层存在的边界约束条件之一,尤其在高原晴空区。 此外,本文还利用资料对本文所提出的混合层数学模式进行了验证和定性分析。

| Abstract: | After analyzing the data of the Tibet Plateau Meteorology Experiment P.R.C-U.S.A ( 1986 ),the vertical structure of the plateau mixed-layer and the influence of inversions are discussed in this paper.
Measured data manifested the stratified layers in the vertical direction. The predicted results from the mathematical model based on the dissipation structure theory for the convective full-mixed layer in Tibet region were in good agreement with the data.Therefore, this model can be used as a method for estimating the strength of inversions over the convective mixed-layer. |
