What Is An Arctic Blast. What is an arctic blast? This occurs fairly regularly during. This is extremely cold air that moves southward from northern canada and alaska. An arctic blast is defined by the us national weather service as when “very cold air masses that typically originate in the siberian region of asia, cross over the north pole into canada and push south and east into the lower united states”. Many times during winter in the northern hemisphere, the polar vortex will expand, sending cold air southward with the jet stream (see graphic above). The arctic polar vortex is a band of strong westerly winds that forms in the stratosphere between about 10 and 30 miles. Usually, there's a barrier keeping that arctic air at the north pole — the jet stream, a river of strong winds that often travels west to east across the u.s., following boundaries between cold and hot air. A mass of cold air flowing from the polar regions to lower latitudes can generate an abrupt and dramatic. This arctic outbreak resulted from a late december through early january sudden stratospheric warming event, which occurs when temperatures in the polar region's stratosphere rise dramatically.
