Hines和Tarasick(1987)关于重力波对气辉辐射影响的理论被扩展到考虑更复杂的气辉化学,包括多步和多步产生机制,淬火和其他损失过程。注意非稳态化学,因为参与OH* 生产的一些物种的时间常数与重力波周期相当。本文给出了亮度与温度波动之比η与发射化学的关系式,并将其推广到其它发射中。对于OH气辉的特殊情况,我们详细研究了Llewellyn等人(1978)和Lowe(1991)的猝灭率。淬火被发现是重要的η的预测所获得的结果进行了比较,在OH气辉中的重力波的有限的一组已发表的观测。虽然理论预测两组速率的η行为存在显著差异,但现有数据不足以得出确切的结论。
The theory of Hines and Tarasick (1987) for the effects of gravity waves on airglow emissions is extended to consider more complex airglow chemistries, including multiple and mutiple-step production mechanisms, quenching, and other loss processes. Attention is given to nonsteady state chemistry, since the time constants of some species involved in OH* production are comparable with gravity wave periods. Relations for the dependence of η, the ratio of brightness to temperature fluctuations, on emission chemistry are presented in a generalized form which is readily applicable to other emissions. The specific case of OH airglow is examined in detail for the quenching rates of Llewellyn et al. (1978) and for those of Lowe (1991). Quenching is found to be important to predictions of η The results obtained are compared with the limited set of published observations of gravity waves in OH airglow. Although the theory predicts significant differences in the behavior of η for the two sets of rates, the existing data are not adequate to draw firm conclusions.
