Okay, today’s word(s) of the day are “polar vortex”. It’s the terminology that all of our local weather stations are using to describe what caused this sudden dip in temperatures. So being the good research librarian that I am (and since I’m off today), I did a little digging around. First I re-read a couple of recent articles I posted last month in “The arctic ice stirs the world“.
Then I did some more digging and came upon this article entitled “Melting Arctic Ice May Lead to Severe Weather Changes” at SciTechDaily. It goes into great detail how the weakening polar vortex up in the arctic affects the jet stream which then allows the colder air to dip so far south.
Brrrrrrrr!
