Abstract

Gravity waves (GWs) strongly influence dynamics in the mesosphere and lower thermosphere (MLT) and play a critical role in transporting momentum from the lower atmosphere to the middle and upper atmosphere. Momentum deposition due to gravity wave dissipation and breaking causes drag on zonal and mean winds within the MLT [1,2]. Breaking GWs are accompanied by multifaceted dynamics, causing local forcing on the background mean flow, and generating secondary GWs [3]. These dynamics are especially important for the broader understanding of momentum transport throughout the atmosphere and within the MLT.
