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.
