Adiabatic, Air Mass, Air Flow

Adiabatic temperature change

As pressure decreases, the temperature of the gas decreases.

Dry adiabatic rate

Air Pressure decreases as the air drops in temperature, at a rate of 5.50 degrees Fahrenheit for each 100 feet.

Wet adiabatic rate

Heat condensation is added to the air and slow the change of temperature, at a rate of 5.50 degrees Fahrenheit to 3.5 degrees Fahrenheit for each 1000 feet.

Air mass

A large body of air that has (about) the same conditions throughout.

Air mass can have either…

Cold dry air or warm moist air.

Characteristics of air mass

Depends on where it formed and it must stay long enough to pick them up.

Formation of air mass

Mostly forms over polar or tropical regions.

Air mass forms over continets

Continental air masses.

Air mass forms over oceans

Maritime air mass.

Air mass may change a regions area’s…

Temperature and humidity based on the characteristics of that air mass.

Moving air mass causes a change in the…

Weather when they contact different conditions.

Air mass move from…

Winds and jet streams, pushing them along.

Cold air mass moves towards…

The equator.

Warm air mass moves towards…

The poles.

Air always flows from…

High to low pressure.
