The topography of Greenland is very striking in that as a plateau that is over 3 km high at some points. As such it presents a very significant barrier to atmospheric flow in the North Atlantic. Not coincidentally, the Icelandic Low sits off of the eastern side of the island, and provides a steering mechanism for storms moving off the coast of Newfoundland and Labrador across the North Atlantic. Deep synoptic scale cyclones can often be seen to actually impinge on the southern tip of Greenland, known as Cape Farewell. Subsequently, high wind speed events downstream of Cape Farewell over the Irminger Sea, known as tip jets, often occur. Some of these events have been simulated with the Penn State – NCAR Mesoscale Model version 5 (MM5) and the mesoscale structure of the high wind speed events has been examined. These simulations will be presented along with an investigation of the formation of the tip jet, and its fine structure.
