A Numerical Study of Internal Waves in the Atmosphere.

Abstract

The particular problem studied in this research is that of the flow of an inviscid incompressible fluid of finite altitude which exhibits density and pressure stratification in the direction transverse to the flow. The fluid is bounded below and above by a solid boundary. The flows examined have been two-dimensional; the direction of the flow is taken to be the x direction and the transverse altitude variable is the z direction. None of the flow variables depend on the y coordinate, taken to be normal to the x and z directions and thus the flow is planar and takes place in the x-z plane. The report attempts to describe the perturbations created in this type flow due to the presence of a mountain ridge type barrier positioned on the lower boundary.
