Numerical Simulation of the Influence of Small Scale Mountain Ranges on a Baroclinc Wave.
A 6-level hemispheric primitive equation model was numerically integrated to examine the influence of various mountain ranges on a baroclinic flow. The objective was to simulate the apparent topographically-induced cyclogenesis that occurs over south central Alaska and isolate the mechanisms involve...
