提出了一个理论来解释潮汐引起的振荡的OH夜光的发射强度I和旋转温度T。该理论包括H，O，O3，OH和HO2之间的光化学反应，以及等温均匀旋转大气中潮汐的完整动力学。比值是指扰动量，上杠表示平均值）取决于基本状态大气结构、次要成分标度高度，特别是O的标度高度和OH排放高度。对于半日和周日迁移模式，η的振幅约为1 - 2.5，相位约为10 °-30 °。
A theory is presented to explain tidally induced oscillations in the emission intensity I and rotational temperature T of the OH nightglow. The theory includes photochemical reactions among H, O, O3, OH, and HO2 and the complete dynamics of tides in an isothermal, uniformly rotating atmosphere. The ratio refers to a perturbation quantity and the overbar signifies an average) depends on basic state atmospheric structure, minor constituent scale heights, especially that of O, and altitude of OH emission. For both semidiurnal and diurnal migrating modes, η has an amplitude in the approximate range 1–2.5 and a phase between about 10° and 30°.
