A Dynamical-Chemical Model of Wave-Driven Fluctuations in the Sodium Nightglow

在中层顶高度（85km）重力波和潮汐对大气排放的扰动进行建模，可以深入了解该地区化学和动力学之间的耦合。如果没有理论模型作为指导，对引力波和潮汐的夜光观测的解释将存在模糊性。Na-D夜光从未在重力波强迫方面被模拟过。正如所揭示的那样，在激光雷达测量中，重力波对钠层的影响的建模到目前为止只包括动力学，而没有考虑化学。我们建议通过开发一个结合动力学和化学的模型来模拟钠夜光中重力波驱动的波动。这个新模型将使用最新的钠化学自洽模型，包括涉及中性物质、离子和簇离子的反应。动力学将以线性重力波理论为基础，但将包括涡流扩散率的广义效应。利用全天相机系统测量的Na和OH夜光将为我们提供两种夜光的水平波长、周期、传播方位角和相对强度变化，以便与Na夜光波动模型和OH夜光进行比较。

Modeling of the perturbations of atmospheric emissions due to gravity waves and tides at mesopause altitudes (85km) provides insight into the coupling between chemistry and dynamics in this region. Without theoretical models to serve as a guide, ambiguities will exist in the interpretation of nightglow observations of gravity waves and tides. The Na-D nightglow has never been modeled in terms of gravity wave forcing. The modeling of the effects of gravity waves on the Na layer, as revealed, in lidar measurements have until now only included dynamics and not considered chemistry. We propose to model gravity wave-driven fluctuations in the sodium nightglow by developing a model that incorporates both dynamics and chemistry. This new model will use the most recent self-consistent model of the sodium chemistry, including reactions involving neutral species, ions and cluster-ions. The dynamics will be based on linear gravity wave theory but will include the generalized effects of eddy diffusivities. Na and OH nightglow measured with an all-sky camera system will provide us with the horizontal wavelength and period, and azimuth of propagation and the relative intensity variations of the two nightglows for comparison with the Na nightglow fluctuation models and OH nightglow.
