Abstract

A large-scale gravity wave (GW) was observed spanning the whole of Greenland. The GWs proposed in this paper come from a new jet-topography mechanism. The topography compresses the flow and triggers a change in u- and v-wind components. The jet becomes out of geostrophic balance and sheds energy in the form of GWs to restore the balance. This topography-jet interaction was not previously considered by the community, rendering the impact of the gravity waves largely unaccounted for.
