Pseudo-adiabatic flow over a two-dimensional ridge

We consider a linearized, two-dimensional flow of moist air over a ridge. The moisture is assumed to be in a layer adjacent to the mountain and the cloud that forms as a result of the wave induced motion is assumed to be next to the mountain. We model pseudo adiabatic effects as follows: Latent heat is released when vertical displacements exceed a fixed quantity, ζ and when the motion is upwards. In the let of the cloud warm and cold wakes are found to alternate with height. Although we do not consider Coriolis forces, the presence of these warm wakes might have important implications in cyclogenesis in the Ice of mountain chains.
