The weather folk had predicted bitter sub zero cold over night. Early this morning my kitchen thermometer read a chilly PLUS 11 degrees. Car started trouble free, and his thermometer dropped from the toasty PLUS 29 degrees in the garage to PLUS 11 degrees as I pulled onto Rt 18 (Three Mile Hill Road). I cruised down hill into Franconia some 1000 feet below my place at Mittersill. At the bottom of the hill in Franconia it was MINUS 5 degrees. We had a 16 degree temperature inversion in merely 4 miles. That's strong.
NOAA keeps temperature records over the whole world gong back to the 1600's when the thermometer was invented. By the 1980's they had some 14,000 stations reporting. Then in 1990 occurred the great purge, some 7000 stations were dropped. I have to wonder what dropping all those stations did to the world average temp, when we have a 16 degree temperature difference over a distance of only 4 miles.
