An air mass is a large body of air that has relatively uniform temperature and humidity characteristics. The regions where air masses form are referred to as air mass source regions. If air remains over a source region long enough, it will acquire the properties of the surface below. Ideal source regions are regions that are generally flat and of uniform composition. Examples include central Canada, Siberia, the northern and southern oceans and large deserts.
When a cool air mass and a warm air mass meet, a stationary front is formed. This occurs when the boundaries between the two air masses do not move, leading to relatively stable weather conditions in the region.
When a warm air mass moves into an area where a cold air mass is located, it is called a warm front. At a warm front, the warm air mass rises over the cold air mass, leading to gradual temperature increases and cloud formation.

Stationary front
An air mass is a body of air. It has similar characteristics to the land on top of which it forms. Fronts are the boundaries in between two different, or same air masses. (e.g: a cold front is when a cold air mass hits a warm air mass and quickly pushes the warm air mass upward.)
The boundaries between air masses are called front. The types of air mass and movements involved determine the type of front. Warm front: a warm air mass plows into a cold air mass. Cold front: a cold air mass plows into a warm air mass. Stationary front: The warm and cold air masses move little relative to one another. Occluded front: A cold front catches up with a warm front, sending the warm air mass aloft. Dry line: a dry air mass plows into a moist air mass.
When a cool air mass and a warm air mass meet, a stationary front is formed. This occurs when the boundaries between the two air masses do not move, leading to relatively stable weather conditions in the region.
The leading edge of a mass of air with certain, uniform moisture and temperature characteristics is called a front. i.e. The leading edge of a relatively warm air mass is called a warm front. The leading edge of a cooler air mass is called a cold front.

A large body of air with relatively uniform properties is called an air mass. Air masses are characterized by their temperature and moisture content, which is influenced by the region over which they form. When an air mass moves over a different area, it can bring its unique weather conditions to that region.
