Abstract

Airglow imaging observations using Utah State University Mesospheric Temperature Mapper (MTM) have been analyzed to investigate short-period gravity waves and their horizontal parameters and propagation characteristics in the mesopause region over Maui, Hawaii (20.7° N, 156.3° W). Typical average wave parameters are horizontal wavelength of ~25 km, phase speed of ~43 m/s and observed period of ~10 min.

Here we present the example of momentum fluxes carried by a vertically propagating short-period gravity wave observed in both OH and O₂ airglow emissions. Utilizing measurements of the local background wind field provided by the collocated University Illinois meteor radar, the ground-relative and intrinsic wave parameters and hence the propagation nature of the wave were derived.
