What Happens When a Cold Front Meets a Warm Front? | Sciencing
Because cold air is heavier or more dense than warm air, the cold air mass moves by fair, clear weather, although some light precipitation may occur. I need to know what type of precipitation occurs when warm and cold air mass meet. The most common are cold fronts, warm fronts, and occluded fronts. What Happens When a Cold Front Meets a Warm Front? When warm and cold air masses meet and form a stationary boundary or front, there is no. When a moving cold air mass meets a warm air mass, that is lighter, it tends to Cold fronts form typically at our latitudes, when the cold dry air from the Polar.
This side of the mountain is called the windward side and typically hosts a great deal of cloud cover and precipitation. The other side of the mountain, the leeward side, is generally less lucky. The airflow loses much of its moisture in climbing the windward side. Many mountain ranges virtually squeeze incoming winds like a sponge and, as a result, their leeward sides are home to dry wastes and deserts.
When a warm air mass and a cold air mass collide, you get a front. Remember how low-pressure warm air rises and cold high-pressure air moves into its place? The same reaction happens here, except the two forces slam into each other.
The cold air forms a wedge underneath the warm air, allowing it to basically ride up into the troposphere on its back and generate rain clouds. There are four main kinds of fronts, classified by airflow momentum. In a warm front, a warm air mass moves into a cold air mass. In a cold front, the opposite occurs.

In a stationary front, neither air mass advances. Think of it as two fronts bumping into each other by accident. Deserts, plains, and oceans typically cover very wide areas with relatively few topographical variations.
A stable atmosphere, in which high winds are absent, is also necessary for the formation of an air mass.
Air masses are classified according to a two-letter system. The first letter, written in lower case, indicates whether the air mass Cold fronts are usually accompanied by cumulonimbus thunderstorm clouds.
Air masses and fronts
Reproduced by permission of National Center for Atmospheric Research. The two designations are c for continental land air mass and m for maritime water air mass. A second letter, written in upper case, indicates the approximate latitude and, therefore, temperature of the region: A for arctic; P for polar; E for equatorial; T for tropical.
The two letters are then combined to designate both humidity and temperature of an air mass. An air mass that developed in a source region over a large body of tropical water would be labeled mT water, warm. An air mass that developed in a source region over an arctic land-mass would be labeled cA land, cold.
Fronts Air masses create weather as they are moved by winds around the globe. Fronts develop at the boundary where two air masses with different temperatures—and, usually, different humidities—come into contact with each other.
Air Masses and Fronts - body, water, type, form, system, surface, Source regions
The term front was suggested by the Bjerkneses because the collision of two air masses reminded them of a battlefront during a military operation. Words to Know Continental: Referring to very large land masses.

Referring to the oceans. Referring to the surface features of an area. A cold front develops when a cold air mass moves into an area occupied by a warm air mass. Because cold air is heavier or more dense than warm air, the cold air mass moves under the warm air mass.
Cold fronts are usually accompanied by a decrease in air pressure and the development of large cumulus and cumulonimbus clouds that bring rain showers and thunderstorms. Rainfall and winds are most severe along the boundary between the two air masses.
