HEMISPHERIC SOLUTION OF THE OMEGA EQUATION INCLUDING TERRAIN AND SURFACE FRICTIONAL EFFECTS

Abstract

A quasi-geostrophic omega equation for largescale vertical velocities in the atmosphere is solved at the earth's surface, 850-, 700-, 500-, and 300-mb levels for a grid of 1977 points per level covering the major portion of the Northern Hemisphere. The effects of terrain and surface frictional stress on the vertical velocity at the lower boundary are investigated in some detail and applied at the earth's surface. The three-dimensional integration of the resulting equations excludes areas inside the terrain. The mathematical model is programmed for the Control Data Corporation 1604 digital computer to utilize the operational output of machineprocessed data and analyses produced by the Fleet Numerical Weather Facility (FNWF), Monterey, California. The program allows a wide variety of modes of operation and yields a solution for the omega equation in five minutes.
