Abstract

The similarity theory and the model of a turbulent flow over a natural large scale roughness in pressure and temperature gradients are presented in the paper. The general analytical results such as the logarithmic mean veloc- ity and temperature profiles for a turbulent flow over smooth and rough surfaces, the temperature and velocity profiles for a turbulent natural con- vection over a large scale roughness and the velocity defect law for the Ekman layer over a rough surface have been obtained. 1 Introduction The similarity theory was widely applied to solve the turbulent flow prob- lems including atmospheric problems (Brandt! [1], Monin & Obukhov [2], Zilitinkevich & Monin [3]). The usual application of the similarity the- ory concerns only the ave
