EXPERIMENTS WITH A STRATOSPHERIC GENERAL CIRCULATION MODEL

Abstract

An 18-vertical level primitive equation general circulation model was developed from previous models of the Geophysical Fluid Dynamics Laboratory in order to study the lower stratosphere in detail. The altitude range covered was from the surface to 4 mb. (37.5 km.), the vertical resolution being optimized in the tropopause region to permit a more accurate calculation of the vertical transport terms. A polar stereographic projection was used and the model was limited to a single hemisphere.
