Very interesting read. The variability is fascinating stuff, even for a layman. Not sure if the weather I'm experiencing now would even be considered related to the variability. But last week at this time most of us were in the midst of a crippling blizzard, and today the high in my area was 57°F and all that snow is nothing but a memory. Granted it's common to hear someone in my area say "if you don't like the weather right now, stick around for five minutes," but this recent shift is just amazing.
