摘　　要：A nonlinear, compressible, non-isothermal gravity wave model that involves photochemistry is used to study the effects of gravity wave on atmospheric chemical species distributions in this paper. The changes in the distributions of oxygen compound and hydrogen compound density induced by gravity wave propagation are simulated. The results indicate that when a gravity wave propagates through a mesopause region, even if it does not break, it can influence the background distributions of chemical species. The effect of gravity wave on chemical species at night is larger than in daytime.A nonlinear, compressible, non-isothermal gravity wave model that involves photo- chemistry is used to study the effects of gravity wave on atmospheric chemical species distribu- tions in this paper.
