Probably jet exhaust aimed at the thermometer :-)
I remember when record highs and lows were sort of neat and just part of the normal cycle of weather events. Now they are portrayed as omens of doom.
Coming Next.. ban all beans. Beans cause flatulance.
True enough, because they are pushing global warming. Every weather event is said to be evidence of global warming.
MOST temps are actually recorded at airports...Do NOT know why.
As to registering temp at airports — that is why all temp measurements are crappola. Have been for years.
A couple of years ago a study was published about the thermometers used to measure temp for use in this sort of stuff. There were (& are) rules on where the thermometers can be placed. They include:
*300 yards from anything that could block free flow of air — like buildings and lines of trees
* not in amongst buildings that trap/generate heat.
Basically, these thermometers are supposed to measure temp of air moving across the planet — not stagnated air trapped in an alleyway.
96% of thermometers were inappropriately placed. So much so that almost all measure temps heavily biased towards high readings — like several degrees. This was pointed out years ago and there has been no effort to fix.
Wanna bet why?
