BASIC CRITERIA DEFINING THE INTENSITY OF TURBULENCE IN A MOUNTAIN REGION (OSNOVNYE KRITERII, OPREDELYAYUSHCHIE INTENSIVNOST TURBULENTNOSTI V GORNOM RAIONE),
Abstract
An effort is made to compute the characteristics of air currents in mountainous regions. The study avoids the use of an oversimplified terrain model such as one in which a mountain ridge is treated as a single obstacle of one form or another. The authors take the approach that the complex structure of an air stream in a mountainous area may be represented as a certain smoothed motion U upon which are superimposed macroscalar pulsations U'. These pulsations are the result of the current breakup upon incidence with the mountain ridge. Hence, the mountains are visualized as a lattice wherein the basic generation of turbulence energy occurs in a layer ranging from a certain mean height to the mountain summits. Above this layer the inflow of energy of turbulence is caused by the diffusion from below. (Author)
