EFFECTS OF TOPOGRAPHY ON PROPAGATION AND DEVELOPMENT OF INERTIA GRAVITY WAVE

Effects of topography on the propagation and development of inertia gravity waves are investigated by means of WKBJ method.The equation of wave action conservation is obtained.It is found that the inertia gravity wave tends to propagate to the higher elevation area,meanwhile the amplitudes of the waves increase.While the inertia gravity waves propagate to a lower elevation area,their amplitudes decrease.
