Dear Tom, You have mentioned that the dry adiabatic lapse rate was 5.4 degrees per thousand feet. While flying in the Navy, we used the figure 3.4 degrees, which usually was observed as the outside… ...

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 ...

Dear Tom, What is the “lapse rate”? I have seen that term occasionally. — Fred Manse Dear Fred, When the pressure of dry air changes, its temperature also changes (by “dry air,” the ...

Dear Tom, You have mentioned that the dry adiabatic lapse rate was 5.4 degrees per thousand feet. While flying in the Navy, we used the figure 3.4 degrees, which usually was observed as the ...

Adiabatic cooling is the process that causes the temperature ... If the air is dry, the temperature cools at a rate of 5.5 degrees Fahrenheit ... This is called the dry/moist adiabatic lapse rate.

Dear Tom, What is the “lapse rate”? I have seen that term occasionally. — Fred Manse Dear Fred, When the pressure of dry air changes, its temperature also changes (by “dry air,” the ...

But under dry conditions, the dry adiabatic lapse rate comes into play. This is a meteorological principle that states in a dry atmosphere, air warms at a rate of 5.5 degrees Fahrenheit for every ...

Then, the dry adiabatic lapse rates and moist adiabatic lapse rates run at a different angles. Dry adiabats show the rate at which unsaturated air cools as it rises, while moist adiabats show the ...

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 ...
