Polar jet circulation changes bring Sahara dust to Arctic, increasing temperatures, melting ice

A new atmospheric mechanism by which dust travels from the Sahara Desert across the eastern side of the North Atlantic Ocean towards the Arctic has been discovered. The dust emission was generated by a Saharan cyclone that was triggered by the intrusion of a trough emanating from the polar jet. The poleward transport of warm dust was caused by a meandering polar jet stream.
