Orographically induced cyclogenesis: analysis of numerical experiments.

Abstract

Cyclogenesis induced by an isolated mountain chain in a baroclinic flow is simulated in a channel version of the HIBU (Mesinger-Janjic) Primitive equaion model. The main feaures characteristic of cyclogenesis in the lee of the Alps are reproduced when the mountain interacts with a finite-amplitude baroclinic wave. The distribution of derived quantities like vertical velocity and potential vorticity compare well with those analyzed in case studies. -from Autors
