In section one , by using fice scheme and time - gcm , a model of trace gases and oh airglow affected by gravity wave is set up , then the propagation of nonlinear gravity wave and the effect on trace gases and oh airglow are analyzed . the result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another . in this process , gravity wave undergoes growth , overturning , convection and breaking
在第一部分的工作中，利用全隐欧拉格式和全球热层-电离层-中间层-电动力学环流耦合模式（ time - gcm ），对重力波的非线性传播及其在传播过程中对中高层大气中氧族和氢族成分和与之密切相关的oh气辉辐射的影响进行了数值模拟，结果表明，从对流层向上传播的重力波经历了产生、发展、饱和、对流产生直至破碎的非线性演化，大气的非等温结构加速了重力波在中层顶区的破碎，重力波的非线性传播是小尺度对流和湍流产生的一个重要的源。
