I call BULLSHIT! Here in the Chicago Area we're having one of our COLDEST Decembers on record. Average daily temperatures through December are on average 20 degrees below normal.
Currently it's 6 degrees. I'd sure like some of that "global warming" they're peddling!!!!
Over many decades glider pilots have learned, through multiple observations per flight, that thermals - the rising columns of air mentioned in the article - have a regular spacing. This horizontal spacing is usually 1.5 to 2.5 times the height of the thermal.
Translated into terms of the original article, lower thermals, and the clouds associated with them, are more frequent and closer spaced at low altitudes.
I wonder if their amazing computer models even allowed for multiple thermals over a given area, or just analyzed individual thermals with no relation to adjacent thermals?
