Thermally Driven, Axially Symmetric Circulations of a Planetary Atmosphere. A Dynamical-Numerical Experiment

Abstract

A dynamical-numerical experiment is designed to evolve thermally- driven circulations, symmetric about the polar axis, in the region from equator to pole. The selection of variables and transformations of the hydrostatic equation system (primitive equations) and the development of the numerical analogue are discussed in some detail. The region is discretized into volume modules by 19 levels in the vertical and by 49 equal intervals from equator to pole. The upper boundary is essentially unrestricted. Mass and absolute angular momentum are treated conservatively and in terms of fluxes across module interfaces. Heating rate distributions are prescribed in space and are stepwise introduced to disturb an atmosphere at relative rest or in balanced zonal motion. The fields are portrayed in a representative meridional plane. Pertinent numerical analyses are included and compression-gravity oscillations are analyzed.
