ABSTRACT: The
purpose of the work is to examine the effects of compressibility on air
properties when a wind blows against a sloping mountain surface. Previous
research of air compression effects include the low speed wing and the crests
of surface gravity waves propagating in the wind.
In both cases, an algebraic expression was obtained for the lift force. When
wind blows across a mountain and the
assumption is made that a boundary layer of compressed air forms and
remains attached to the mountain, a physical-chemical theory predicts that the
wind will have no shear and the pressure and density will decrease with
increasing altitude at the same rate. Combining Bernoulli’s law along
streamlines with the cross-stream force balance, pressure gradient equals
centrifugal force, and the perfect gas law for air, is the model used here.
