中文摘要:
      本文对稳定层结大气中近地层湍流的层结订正函数导出了新的形式.据此而对Мопннобхов的湍流普遍函数作出了新的规定.根据该方案对近地层湍流特徵作了若干讨论.最后并绘制了计算近地层湍流特性量的图表,藉此可以很方便而准确地由梯度观测直接估各市地近地层湍流状况.
英文摘要:
      In this paper the turbulent exchange in the surface layer of the stable atmospere is discussed. Firstly, taking the effiect of thermal stratification on turbulence, we derived a new form of the function of Richardson number from the energy balance equation of the turbulent atmosphere. Secondly, we further proposed a reasonable function, which describes the vertical distribution of elements in the stable atmospheric surface layer. Thirdly, we give some graphs which allow us to calculate accurately and quickly the turbulent characteristic values, such as turbulent austousch based on observed data. For comparison with others, some calculations based on observed data are furnished. It shows that our treatment is reasonable and our results are better than Мопннобхов's results.
