This is an air mass.
Air has mass. Mass is a property and does not have mass
warm air mass and cold air mass
Yes air has mass. It is the mass of the air above a point on earth that is responsible for the air pressure.
An Warm air mass
the cold air mass took the place of the large air mass
This air mass often originates as a different air mass in Siberia and is subsequently altered is cP. The air mass that originates over the ocean is the maritime air mass.
What happens is similar to when a warm air mass meets a cold air mass: the Cold Air Mass is forced to Subside beneath the Warm Air Mass. Thusly the warm air is uplifted, it cools and Rain is formed. When a Warm Air Mass meets a Cold Air Mass, the warm air is [again] forced to Rise above the Cold Air Mass, it cools and Rain is formed.
A cold air mass is a mass of air that has colder characteristics than the surrounding air.
This forms a front it can be a cold or warm front
the mass air flow sensor detects the flowing of mass air into the engine while the mass air flow meter detects the amount of mass air flowing into the ingine.
A warm air mass and a cold air mass holds the same amount water vapor but the air mass is smaller
