When a cold air mass catches up with a warm air mass the result is often a blank front apex?
A warm air mass pushes into a colder air mass (the warm front), and then another cold air mass pushes into the warm air mass (the cold front). Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front.
What happens when a cold air mass moves over a warm air mass?
Storms arise if the air mass and the region it moves over have different characteristics. For example, when a colder air mass moves over warmer ground, the bottom layer of air is heated. That air rises, forming clouds, rain, and sometimes thunderstorms.
What front occurs when a warm air mass catches up to a cold air mass and over takes?
occluded front
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 warm air mass meets a cold air mass and takes it over?
Warm fronts
Warm fronts If, on the contrary the warm air mass is moving towards the cold air mass, the warm air mass slowly slips over the cold one, and rises along a vast gently sloping surface: in this case we can speak of a warm front which also brings clouds and perturbation systems.
When a cold air mass replaces a warm air mass is called a front?
When a cold air mass replaces a warm air mass, this is called a cold front. Some characteristics of a called front before passing are winds coming from south or southwest area, warm temperature, falling pressure, and drizzles.
When a cold air mass replaces a warm air mass is called a blank front apex?
With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.
When does a warm air mass overtake a cold air mass it forms a N?
Occluded Front: Forms when a warm air mass gets trapped between two cold air masses. The warm air rises as the cold air masses push to meet in the middle. Weather they bring: The temperature drops as the warm air mass is cut off from the ground & pushed upward.
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.
Where do the polar air masses come from?
Continental polar air masses originate in the snow-covered interior of Canada, Alaska, and the Arctic in the colder months. Lower layers of the air become quite cold, dry, and stable. Much moisture from the air is condensed onto the snow surface.
