When dry air (meaning no clouds) changes pressure, it also changes temperature. If you have ever filled a bicycle tire, you may have noticed the more air you pump into the tire, the warmer the valve ...

A note from a viewer in Moline asks about the adiabatic rate of temperature change. It turns out that when dry air (meaning no clouds) changes pressure the temperature also changes. You've had the ...

Have you ever been hiking and noticed that the air gets cooler as you ascend? Or mountain bike down a mountain and realize the temperature is much warmer at the bottom? This is adiabatic cooling. The ...
