Abstract

These disturbances are trapped by the existence of a subsidence inversion at a height below the crest of barrier-like coastal mountains and propagate alongshore with the coast on the right (left) in the Northern (Southern) Hemisphere. It is shown that the fundamental dynamics of the disturbances is in each case governed by the hydrostatic and semigeostrophic approximations. The latter implies that a geostrophic balance exists between the alongshore velocity of the motion and the across-shore pressure gradient
