## What is a boundary between two air masses that is not moving?

There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move. The motion of air masses also affects where a good portion of precipitation occurs. The air of cold air masses is more dense than warmer air masses.

## What is a non moving boundary between two air masses called?

A stationary front is a non-moving (or stalled) boundary between two air masses, neither of which is strong enough to replace the other.

## What are the boundaries between air masses?

Fronts are boundaries between air masses. Depending on the air masses involved and which way the fronts move, fronts can be either warm, cold, stationary, or occluded. In the case of a cold front, a colder, denser air mass lifts the warm, moist air ahead of it.

## What is the boundary line when neither air mass is moving?

Stationary Front: the boundary between a cold airmass and a warm airmass, where neither airmass is moving, but the temperature difference across the boundary remains (the airmasses don’t mix to reach equilibrium).

## What are the three main air mass boundaries?

Tropical air masses form in low-latitude areas and are moderately warm. Polar air masses take shape in high-latitude regions and are cold. Equatorial air masses develop near the Equator, and are warm.

## What is the boundary between two different air masses which stays over tropical waters?

Air masses over water are called maritime air masses, while air masses over land are called continental air masses. The borderline between two air masses is called a front. There are various types of fronts, including cold, warm, occluded and stationary fronts.

## What are the definite boundaries of air masses of different temperatures?

When air masses collide and clash together air mass boundaries form called fronts. Fronts are identified by the change of temperature based on motion. Now there are a few different types of fronts, but the most common, which we are familiar with here are warm and cold fronts.

## What is the boundary between warm and cool air?

Warm Front – a transition zone between a mass of warm air and the cold air it is replacing. Stationary Front – a front between warm and cold air masses that is moving very slowly or not at all. Occluded Front – a composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front.
