What happens when a cold air mass moves toward a warm air mass?
They push against each other along a line called a front. When a warm air mass meets a cold air mass, the warm air rises since it is lighter. 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 warm air mass moves into an area where a cold air mass is located?
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.
How do the air masses move in a cold front?
Cold Front They move fast, up to twice as fast as a warm front. As a cold front moves into an area, the heavier (more dense) cool air pushes under the lighter (less dense) warm air, causing it to rise up into the troposphere.
When a cold air mass moves into a warm air mass it will get colder and we will have severe weather?

|---|---|
| When a cold air mass moves into a warm air mass, it will get colder and we will have severe weather. What type of front is this? | cold front |
| When a warm air masses gently slides on top of a cold air mass, and you have drizzly rain and then beautiful sunny weather, what front is it? | warm front |
When a cold front catches up to a warm front the result is a?
An occluded front develops when a cold front catches a warm front. For a maturing cyclone, a warm front is progressing northward ahead of the storm center while a cold front is sweeping southeastward. The cool air mass north of the warm front is already in place.
When a warm air mass and a cold air mass meet and stalls the result is a?
When a warm and cold air mass meet, the resulting front generally brings precipitation in some form, bad weather for a short period of time, then moves on. Sometimes, however, fronts stall. This is called a stationary front. Stationary fronts occur when neither air mass has the power to overtake the other.
What happens when two different air masses meet?
•Where two different air masses meet, it is called a front. There are different types of fronts: ◦Warm front – When a warm air mass overrides a cold area, it rises slowly, creating nimbostratus, altostratus, or cirrostratus clouds.
What kind of air masses form over water?
Air masses can be cold (polar) or warm (tropical). They can form over water (maritime) or land (continental). Combining these two dimensions produces four categories: maritime tropical, maritime polar, continental tropical, and continental polar.
Where does warm tropical air meet cold polar air?
It occurs high in the atmosphere where warm, tropical air meets cold, polar air. •Climate zones and their features are also related to the amount of solar radiation an area receives. For example, near the equator where the Sun’s rays are most concentrated, it is always hot, humid, and raining.
What kind of weather is a cold front?
Cold fronts often produce thunderstorms and very bad weather. ◦Stationary front – When a cold air mass and warm air mass flow side-by-side, and neither mass invades the other, weather can be unpredictable.
