cold and warm
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
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.
When the cold front comes, the air mass gets lighter and thinner.
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.
