As this ScienCentral News report explains, scientists are finding that the jet stream, that river of air that pushes storms across the country, is moving towards the north and south poles.

She and co-author Ken Calderia, also with the Carnegie Institution combed 23 years of records to find that, on average, the jet streams are shifting at the rate of 1.25 miles a year, something they believe is connected to global warming. Archer says they were not surprised by the discovery, noting that other studies have found that the atmosphere in the subtropical regions near the equator is heating up and expanding. As the tropical air region expands, Archer notes, “The jet streams are pushed towards... the poles as well.”

Archer adds that means weather patterns will also shift. She says, “Changes to the jets mean changes to the storms, and changes to the storms means changes in precipitation, changes in how much rain and how much snow we can count on.”
