re: re:Interesting
I found another record on the internet.

The greatest temperature change in 24 hours occurred in Loma on January 15, 1972. The temperature rose exactly 103 degrees, from 54 degrees below zero to 49 degrees above zero. This is the world record for a 24—hour temperature change.
I wonder how the barometric pressure changed during that time.
According to the laws of physics, the colder air has greater density, therefore greater weight, so the barometric pressure should have gone down during the time that the air was getting warmer.
It is interesting the way temperature and pressure are interlinked in the atmosphere, if the air heats up it becomes less dense and lighter, if the pressure decreases without the introduction of more heat, then the air becomes cooler.
That just goes to show the constant in Bernoulli’s principle.
v2 + gh + w = constant.
