What are the different kinds of weather fronts?
- Cold Front. A cold front is the leading edge of a colder air mass. …
- Warm Front. Warm
fronts
tend to move slower than cold
fronts
and are the leading edge of warm air moving northward. … - Stationary Front. …
- Occluded Front.
What are the four types of weather fronts quizlet?
- Cold Fronts. When a rapidly moving cold air mass runs into a slowly moving warm air mass, the denser cold air slides under the lighter warm air. …
- Warm Front. A fast moving warm air mass overtakes a slow moving cold air mass. …
- Stationary Fronts. …
- Occluded Fronts.
What are warm and cold fronts?
A cold weather front is defined as the changeover region where a cold air mass is replacing a
warmer
air mass. Cold weather fronts usually move from northwest to southeast. A warm weather front is defined as the changeover region where a warm air mass is replacing a cold air mass. …
What are the 4 types of weather fronts and explain what they are?
Fronts are boundaries between air masses of different temperatures. … The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass. There are four types of fronts that will be described below:
cold front, warm front, stationary front, and occluded front
.
What do all fronts have in common?
At a front, the two air masses have different densities, based on temperature, and do not easily mix. 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.
Winds
are common at a front.
What type of front is still and not moving?
Stationary Front
: a front that is not moving. When a warm or cold front stops moving, it becomes a stationary front.
How does air move in general?
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. … When
the air cools, it drops back to the ground, flows back towards the Equator, and warm again
. The, now, warmed air rises again, and the pattern repeats. This pattern, known as convection, happens on a global scale.
What type of weather does a occluded front bring?
The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring
strong winds and heavy precipitation
. Occluded fronts usually form around mature low pressure areas.
What causes weather fronts?
The answer is “
moisture and differences in air pressure
.” A front represents a boundary between two different air masses, such as warm and cold air. If cold air is advancing into warm air, a cold front is present. On the other hand, if a cold air mass is retreating and warm air is advancing, a warm front exists.
When two air masses meet what happens?
When two different air masses come into contact,
they don’t mix
. 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. At high altitude it cools, and the water vapor it contains condenses.
What do warm fronts seem to have in common?
Warm fronts generally move from southwest to northeast and the air behind a warm front is
warmer and more moist than the air ahead of it
. When a warm front passes through, the air becomes noticeably warmer and more humid than it was before.
What type of weather does a cyclone bring?
While anti-cyclones are associated with periods of fair weather, cyclones are responsible for shorter periods of
foul weather
. This foul weather ranges from overcast skies and steady rains to thunderstorms and gusty winds.
What do cold fronts bring?
As the cold front passes,
winds become gusty
. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning. Atmospheric pressure changes from falling to rising at the front.
How can you tell if a front is warm or cold?
If cold air is advancing into warm air
, a cold front is present. On the other hand, if a cold air mass is retreating and warm air is advancing, a warm front exists. Otherwise, a stationary front is present if the cold air is neither advancing nor retreating from the warm air mass.
What clouds do cold fronts bring?
Cumulus clouds
are the most common cloud types that are produced by cold fronts. They often grow into cumulonimbus clouds, which produce thunderstorms. Cold fronts can also produce nimbostratus, stratocumulus, and stratus clouds.
