RUI: Wave-Induced Nonlinear Response of Chemically Active Species and Associated Airglow Emissions in a Shear Flow

研究了中层-低热层(MLT)区次生物质对重力波中切变流动的非线性响应。作为这种非线性响应的结果的气辉特征被隔离，以便解释现有和未来的测量。一个以前用于成功研究重力波对周围MLT区域的动力学影响的非线性模型被扩展到包括化学活性物质对绝对流动的响应。为了解释气辉测量，确定了相关数量的后续响应，如振动或旋转激发物种的种群和这些物种的能级种群。

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.
