What happens when a cold air mass moves under a warm air mass?

What happens when a cold air mass moves under a warm air mass?

This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain. On the other hand, when a cold air mass catches up with a warm air mass, the cold air slides under the warm air and pushes it upward. As it rises, the warm air cools rapidly.

When a cold air mass moves underneath a warm air mass A is formed?

Cold Fronts
Cold Fronts When a cold air mass takes the place of a warm air mass, there is a cold front (Figure below). The cold air mass is dense so it slides beneath the warm air mass and pushes it up. Imagine that you are standing in one spot as a cold front approaches.

What is the movement of warm and cold air masses?

The Movement of Air Masses: transporting warm air northward and colder air southward. Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses.

What type of air mass is moving in a cold front?

A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.

What is it called when a warm air mass is caught between two cold air masses?

An Occluded Front forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward.

What is the movement of air called?

Air is constantly moving around the earth. This moving air is called wind. Winds are created when there are differences in air pressure from one area to another. In areas of high-pressure (sinking air), air at ground level spreads out, moving away from the high pressure. This is what makes air move, creating the wind.

What is mP air mass?

In air mass. Maritime Polar (mP) air masses develop over the polar areas of both the Northern and the Southern hemispheres. They generally contain considerably more moisture than the cP air masses. As they move inland in middle and high latitudes, heavy precipitation may occur when the air is forced…

What is it called when hot and cold air meet?

The boundary between the two is called a FRONT. Warm fronts occur when light, warm air meets cold air. The warm air rises gradually over the cold air as they meet. As the warm air rises it cools and condenses to form clouds.

What is it called when air moves fast and strong?

When the air moves fast, It is called wind.
