A large mass of warm humid air from the North Atlantic is driving a wedge (ridge of the jet-stream) into the 24-hour darkness of the Arctic nearby the North Pole, in the dead-of-winter. Frigid Arctic temperatures are brought to above freezing, further stunting sea-ice growth. The low pressure “eyes” of these cyclones reach 951 mb; the same as the recent “weather bomb” of the east coast of the US. I show you the easy-to-use Earth Nullschool tool to track the jet-stream, polar vortex, temperatures, pressures, moisture and clouds.
