At the mouth of Baffin Bay just off the West Coast of Greenland today hurricane force wind gusts are blowing in from the south.
This roaring invasion of warm air originates from the Central Atlantic along a latitude line south of the Azores. It climbs hundreds of miles north to where it is intensified between a grinding 975 mb low off Labrador and a massive 1042 mb high squatting over Central Greenland. Temperatures in this warm air mass range from near 50 degrees (F) over Southwestern Greenland to around 40 degrees (F) over the mouth of Baffin Bay. Or between 9 and 36 degrees (F) above normal for this time of year.
(Hurricane force wind gusts are driving a wedge of above freezing air into Baffin Bay and over Western Greenland at a time when these regions should be seeing well below freezing conditions. Image source: Earth Nullschool.)
