ens When a Cold Front Meets a Warm Front?

Most people understand the basics of cold and warm fronts: Passage of a cold front cools things down, and passage of a warm front warms things up. But warm fronts and cold fronts don’t simply follow one another in orderly procession. They can also merge in what’s known as an occluded front, an important stage in the development of many of the great weather-making low-pressure systems known as midlatitude cyclones.

TL;DR (Too Long; Didn’t Read)

When a cold front overtakes a warm front, it creates what’s called an occluded front that forces warm air above a frontal boundary of cooler air masses.

Frontal Action of the Midlatitude Cyclone

Midlatitude (or extratropical) cyclones – which shouldn’t be confused with tropical cyclones or hurricanes – form along weather fronts, which are boundaries between air masses of different temperatures and associated conditions. A wave along the front creates a low-pressure disturbance, which draws in winds that – because of the rotation of the Earth – spiral around the low. The leading edge of the warm air mass, where it rises over denser cold air, creates a warm front; that of the cold air mass behind, which shoves under the warm sector behind the warm front, creates a cold front.

Formation of an Occluded Front

In an occluded front, the trailing cold front overtakes the preceding warm front. This is conventionally described as the cold front “catching up” to the warm front. However, while it’s true that cold fronts tend to move faster than warm fronts, recent research suggests more underlying cyclonic processes cause the frontal mashup. Regardless, an occluded front involves the warm air behind the warm front behind forced aloft, the low-pressure center of the cyclone moving away from the frontal boundary, and the cold front coming into contact with the cold air mass originally downwind (so to speak) of the warm front.

Warm-type vs. Cold-type Occlusions

Two types of occluded front exist: the warm-type and the cold-type. They’re distinguished by the relative temperatures of the air mass ahead of the occlusion – in other words, the air mass ahead of the original warm front – and the air mass behind the cold front. If the air behind the cold front is colder than the air ahead of the occlusion, it shoves beneath that air (because it’s denser) to form a cold-type occluded front. If the air behind the cold front is warmer than the air ahead, it rides over it to form a warm-type occluded front – which appears to be the more common case. In either situation, the lighter warm air representing the air mass originally between the warm and cold fronts sits above the boundary between the two cooler air masses.

Weather Map Symbols

Colored weather maps represent cold fronts with blue lines studded with blue triangles pointing in the direction of the front’s movement. Warm fronts appear as red lines marked with red half-circles that also point toward the direction of frontal movement. An occluded front shows on the map as a combination of these symbols: a purple line alternating with purple triangles and half-circles.

Weather Along the Occluded Front

A forward-moving front, whether warm or cold, causes one air mass to lift above another; by forcing the air mass to its condensation level, this creates clouds and often precipitation. Weather along an occluded front can take many forms, but some combination of cold-front and warm-front effects often takes place, with anything from light to heavy precipitation often diminishing to clear skies after the front’s passage.

Frequently Asked Questions About what type of front occurs when an active cold front overtakes a warm front?

If you have questions that need to be answered about the topic what type of front occurs when an active cold front overtakes a warm front?, then this section may help you solve it.

What happens in a middle latitude cyclone when a cold front passes over a warm front?

The boundary separating the fresh cold air mass (to the west) from the more seasoned cool air mass already present north of the warm front is formed by the cold front rotating around the storm and catching the warm front.

What occurs when a warm front collides with a cold front?

At our latitudes, over the Atlantic, cyclonic areas form continuously; these are fed by the Azores anticyclone and the Polar anticyclone. An occluded front forms when a cold front approaches a warm front, forcing all the warm air to rise to higher altitudes and the cold air to stratify near the ground.

What is the phenomenon known as when a cold front overtakes a warm front?

Affected Fronts

When a warm air mass passes over a cold air mass, what kind of front results?

Colliding air masses can create four different types of fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts. A warm air mass overtakes a slowly moving cold air mass.

What occurs when a front is obscured?

A warm air mass caught between two cold air masses rises as the two collide in the middle, the temperature falls as the warm air mass is occluded, or “cut off,” from the ground, and is pushed upward, and this is how an occluded front forms.

The polar front occurs where?

The polar front, which can be found in both hemispheres around 60° latitude, is the boundary between the polar cell and the ferrel cell in meteorology.

when a warm thing is forced to become cold?

When a cold front overtakes and catches up to a warm front, two fronts come together to form an occluded front.

What kind of front forms when warm and cool air collide?

A cold front develops when cold air moves in the direction of warm air, undercutting the warmer air in front of it and forcing it to rise above it more quickly than at a warm front, where it may cool more quickly and form large cumulonimbus clouds.

Quiz: What happens when a cold front overtakes a warm front?

When a cold front overtakes a warm front, an occluded front develops.

Quiz: What do you call it when the cold front overtakes the warm front?

When a cold front overtakes and catches up to a warm front, two fronts come together to form an occluded front.

What happens when cold air is replaced by warm air?

A warm front is formed by the warm air mass’ leading edge rising over colder air that is denser; a cold front is formed by the cold air mass’ trailing edge pushing beneath the warm sector of the warm front.

Occluded fronts are either warm or cold.

A cold occlusion, which behaves similarly to a cold front in that the colder air behind the front undercuts and pushes up the air ahead of it, occurs when the air behind the occluded front is colder than the air ahead of it. The warm occlusion is the other type of occluded front.

What does “occluded front” mean exactly?

Occluded fronts, which typically form with mature low pressure areas and behave like both warm and cold fronts, get their name from the fact that when the cold air pushes underneath the warm air, it lifts the warm air up from the ground, making it hidden or occluded.

What are stationary and occluded fronts?

Occluded Front: A composite of two fronts formed as a cold front passes over a warm or quasi-stationary front. Stationary Front: A front between warm and cold air masses that is moving very slowly or not at all.
