Warm Humid Air Penetrates Arctic Cold Dome: 2 of 4 // Published on Feb 26, 2018

Above the Arctic sea-ice sits a dome of cold, dry, heavy air.  Arctic temperature amplification results in very wavy, pronounced crests and troughs in the jet stream, so warm moist air moves rapidly northward in atmospheric river fingers that often slice through the dome causing above freezing temperatures at the ice surface, and also deflect upwards at the dome surface.

With fast enough wind speeds they can penetrate up high into the atmosphere and slice the polar vortex into multiple loops, and feed back to further break the jet streams.
