Chemistry and Transport in the Middle Atmosphere: A Simple Interactive Model
Abstract
The overall goal of the research program was the development of a coupled dynamical, chemical, and radiative model of the Earth's middle atmosphere. Two specific tasks were pursued. First, we developed a coupled 2-D transport and chemistry model utilizing a new algorithm for the transport program module. This scheme was based on work done by Prather (J. Geophys. Res., 91, 6671, 1986). Prather's original formulation was extended to account for the sphericity of the atmosphere and to include eddy diffusion and chemistry. Analytic solutions for a series test experiments were developed by which the new numerical procedures could be tested. The second task supported by this grant consisted of the development of an efficient, accurate radiative transfer model of the middle atmosphere. The amplitude of the 2-D transport circulation in the middle atmosphere is proportional to the net diabatic heating rate, Q, which is approximately given by the difference between the solar heating and thermal cooling rates.
