When the cold front comes, the air mass gets lighter and thinner.
A cold front develops when a cold air mass advances, lifting the air in a warm air mass.
No. The warm air mass always rises above the cold air mass. And if the cold air is advancing, that makes it a cold front.
When a cold FRONT catches up to a warm FRONT it is called an occluded front.When a cold AIR MASS displaces a warmer AIR MASS it is a cold front.Occluded front
cold and warm
A cold front is the transition zone were a cold air mass replaces a warm air mass. A warm front is a transition zone were a warm air mass replaces a cold air mass.
Air masses that are cold and forms over polar regions is polar. A cold front occurs when a cold air mass meets and displaces a warm air mass. A front that forms when a warm air mass is trapped between cold air masses and forced to rise is called a occluded front.
If the cold air is advancing, that makes it a cold front.
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.
