Abstract:

A three-level numerical model of the stratosphere is formulated to yield predictions based on the thermodynamic and ozone equations. These latter include long - and short - wave radiation and photochemical ozone production together with eddy diffusion and three-dimensional geostrophic advection, the vertical velocity being derived from a quasi-stationary vorticity equation. The model is bounded and forced from below by continuous specification of 70 - mb heights and 163 13 - mb temperatures. Time integrations with moderate, intense and negligible forcing show that the radiative-photochemical equilibrium state is unnatural, planetary waves are important transporters of heat and ozone, high-latitude warmings do occur and their intensity depends upon the forcing, and in situ warming is mainly due to subsidence.
