Polar, tropical, continental, and temperate
warm and wet
Tempature and humidity are almost always the 2 traits given, even if the terms are vague, such a as a warm moist air mass or a cold dry air mass. The terms are in reference to the air mass in an area before the new one being described.
Air masses are described by two basic characteristics. Temperature and moisture, or humidity, are the main characteristics that define an air mass.
Good air-mass source regions are dominated by high pressure where subsidence forces air towards the surface. These high pressures also enable air to move outward from the source region.
Same as any other mass. The mass is sometimes (informally) described as the "amount of substance" something has.Same as any other mass.

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.
the cold air mass took the place of the large air mass
An Warm 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.
