Antiphase OH and OI airglow emissions induced by a short-period ducted gravity wave

摘要

Numerical simulation of a ducted gravity wave event suggests that OH (8,3) and O(S-1) 557.7 nm airglow emissions layers may exhibit opposite-phase intensities when perturbed by a short-period wave undergoing vertical reflection. This effect arises due to the time and temperature dependance of the OH excitation reaction, coupled with the linear polarization properties of vertically-standing waves.
