The nonlinear response of minor species in the mesosphere-lower-thermosphere (MLT) region to sheer flows in gravity waves is investigated. Airglow signatures that are a consequence of this nonlinear response are isolated for the purpose of interpreting existing and future measurements. A nonlinear model previously used to successfully investigate dynamical effects of gravity waves on the ambient MLT region is expanded to include the response of chemically active species to sheer flows. Subsequent response of related quantities, like populations of vibrationally or rotationally excited species and the energy level populations of those, are determined for the expressed purpose of interpreting airglow measurements.

本文研究了重力波中中层-低热层（MLT）区微量组分对切变流的非线性响应。 气辉签名，是这种非线性响应的后果被隔离的目的，解释现有的和未来的测量。 一个非线性模型，以前用来成功地调查重力波的动力学效应的环境MLT区域扩展到包括化学活性物质的响应，以剪切流。 随后的响应相关的数量，如人口的振动或旋转激发的物种和能级人口的那些，被确定为解释气辉测量的表达的目的。
