The last 10 years has seen a resurgence of interest in the role that Greenland plays as an obstacle to flow in the Northern Hemisphere. In particular, a number of intense mesoscale wind systems have been identified that arise out of interactions of extra-tropical cyclones with the topography of southern Greenland . These include: tip jets- narrow jets of westerly wind extending eastwards from the Cape Farewell region; reverse tip jets - narrow jets of easterly wind extending westward from the Cape Farewell and barrier flow- topographically confined northeasterly flow along the east coast of Greenland . In this talk, Professor Moore will describe these wind systems and the physics behind their origin as well as their role in driving ocean currents and forcing deep ocean convection in the Irminger and Labrador Seas . He will also describe an experiment, the Greenland Flow Distortion Experiment (GFDex), which will take place this coming winter. GFDex will provide the first in-situ observations of these wind systems and the air-sea interaction associated with them.
