Hot Alaska, Cold Georgia: The Shifted Polar Vortex Turned Winter Upside-Down reports Ryan Koronowski at Climate Progress. The jet stream morphed from a gently sinuous circulation of circumpolar winds to a dramatically loopy one. The western, “downhill” side of such a loop over North America brought polar cold deep into the southern US. Simultaneously, the dramatic “uphill” side preceding it (further west )brought air from an unusually warm Pacific up to Alaska, delivering dramatically warm weather. Both events disrupted life north and south. Such jet stream “mood swings” are predicted to occur more often under continuing global heating – so get ready for even more interesting times!
Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
