A fast method for calculating scaledependent photochemical acceleration in dynamical models of the stratosphere
Abstract
It is shown that photochemical acceleration of the thermal relaxation rate in the stratosphere may be expressed as a matrix multiplication between a square matrix, which may be calculated for quite general conditions, and a vector representing the deviation of temperature from an equilibrium profile. Such a matrix is presented and its form discussed. Use of this matrix allows for temperature perturbations of any vertical scale and thus provides an accurate, as well as fast, method for calculating photochemical acceleration suitable for use in numerical models of stratospheric dynamics. The inclusion of the ozone 9.6 micron band into the heating rate calculations is shown to reduce the photochemical relaxation rate in the upper stratosphere.
