The Topographical Effect upon the Jet Stream in the Westerlies

Abstract

It is the purpose of this paper to make clear the effect of topography upon the jet stream. As the numerical example, the strong jet stream over the Far East is discussed quantitatively in connection with the Himalays. The fundamental concept we used is that the stationary pattern is obtained if η+αh (η: absolute vorticity, α; constant, h: height of the topography) coincides with the stream function. The difference of roles of topographical effect upon the stationary pattern between the Himalayas and the Rocky mountains is also discussed.
