At high regions in the atmosphere, known as the mesosphere and lower thermosphere, gravity waves (buoyancy waves) move and break depositing large amounts of momentum and energy into the background atmospheric state. Because of how quickly these waves change, it's difficult to model the regular patterns seen in their behavior and the local atmospheric environment. This is particularly true at under-observed high-latitudes. To fill this gap, we present an analysis of hydroxyl airglow (faint infrared light emission) images taken over multiple years in a polar environment, highlighting potential relationships between gravity waves and phenomenon such as the polar vortex and atmospheric tides.
