Orographically induced spontaneous imbalance within the jet causing a large-scale gravity wave event
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...
