What happens when a warm air mass passes over a cold 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.
What happens to the warm air when it overtakes the cold air?
When a warm air mass meets and overrides a cold air mass, a warm front forms. The warm air moves up and over the cold and generally brings drizzly precipitation. If a fast-moving cold air mass overtakes a slower-moving warm front and then continues advancing and catches another cold front, an occluded front forms.
When a cold dry air mass overtakes a warm humid air mass?
Cold front: a fast-moving cold air mass overtakes a warm air mass; the warm air is pushed upward. Warm front: a warm air mass overtakes a slow-moving cold air mass; warm air moves over the cold air.
What happens when one air mass overtakes another air mass What does this do to the weather?
One air mass is lifted above the other, creating a low pressure zone. If the lifted air is moist, there will be condensation and precipitation. The greater the temperature difference between the two air masses, the stronger the winds will be. Fronts are the main cause of stormy weather.
How does density relate to cold and warm air masses?
How does density relate to cold and warm air masses? Warm is less dense and cold air is more dense. An air mass is a large body of air that has the same temperature and moisture level throughout.
What happens when a cold air mass meets a warm air mass?
What Happens When a Cold Air Mass Meets a Warm Air Mass? When a cold air mass meets a warm air mass, a front is formed; if the cold air is replacing the warm air, it is known as a cold front. Cold fronts frequently cause rain showers or thunderstorms because they force air in a steep upward direction at the front’s edge.
When does a warm front form what happens?
Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.
When do two air masses come together it is called a front?
Where two or more air masses come together, the boundary between them may be quite distinct; it is called a front. Frontal zones, where lighter air masses are forced over denser air masses, are regions of considerable weather activity.
What kind of air masses originate over land?
Cold and dry air masses that originate over landmass are called continental polar mass. Cold and moist air masses that originate over water are called maritime polar mass.
