Abstract

The paper aims to study the effect of gravity wave propagation on atmospheric trace gas distributions in the upper mesosphere and lower thermosphere. A two-dimensional, time-dependent, nonlinear photochemical-dynamical coupling gravity wave model is made. Important photochemical reactions in middle atmosphere are considered in this model. The model includes diabetic process produced by photochemistry and the dynamical effect of gravity wave on atmospheric chemical species. The pseudospectral method is used in the horizontal direction and the finite difference approximations are used in vertical direction z and time t. FICE method is used to solve the model. The results of the simulation by using the model show that the gravity wave propagation can induce large change of the mean profiles of oxygen compound and hydrogen compound in mesopause region. The effect of gravity waves on the distributions of the atmospheric species in night is greater than that in daytime.
