中文摘要
扩展了量化重力波(特别是传导重力波)稳态传播的模型,以研究波传播的时间依赖性以及这些波对中间层气辉的影响。 这项研究预计将首次建立一个连贯的理论,用于创建“墙事件”,有时在 OH 气辉图像中看到大振幅、明显的气辉亮度梯度。 所使用的模型是已建立的频谱全波模型,适用于处理时域中的瞬态波现象。
英文摘要
A model to quantify the stead-state propagation of gravity waves, in particular ducted gravity waves, is expanded to investigate the time dependence of wave propagation and the impact of these waves on airglow in the mesosphere. The research is expected to establish, for the first time, a coherent theory for the creation of "Wall Events" sometimes seen in OH airglow images as large amplitude, distinct, airglow brightness gradients. The model to be used is an established Spectral Full-Wave model, which is adapted to treat transient wave phenomena in the time domain.
