大气边界层的数值模式

A NUMERICAL MODEL OF ATMOSPHERIC BOUNDARY LAYER

中文摘要:

      从大气边界层温湿特征的模拟,讨论模式的设计和处理。模式计算所得位温,混合比垂直廓线和混合层厚度等随时间变化基本反映实际大气边界层的一些特点。并从地气之间热量收支、土壤热传导方程出发计算地面温度日变化。利用Clarke的Wangara资料计算了24小时内它们的变化,并与观测值进行比较。本文还对温湿预报方程的数值解的稳定性进行了讨论。

英文摘要:

      The scheme of the atmospheric boundary layer model is discussed in simulating the thermodynamic character. The potential temperature and mixing ratio profiles and their variations with time are computed from the model. The diurnal variations of surface temperature and mixed layer height are estimated from the model. According to Clarke's Wangara data, comparison is made between observed and computed values. Computational stability for the forecasting equations of potential temperature and humidity is discussed in this paper.
