## When a cold air mass catches up with a warm air mass the result is often a blank front?

Occluded Fronts
Occluded Fronts An occluded front usually forms around a low pressure system. The occlusion starts when a cold front catches up to a warm front. The air masses, in order from front to back, are cold, warm, and then cold again. Coriolis Effect curves the boundary where the two fronts meet towards the pole.

### When a cold air mass catches up to a warm air mass is called a n?

Describe The Motion Of Air Masses : Example Question #1 Explanation: The answer is “a cold front.” A cold front moves faster than a warm air mass. An occluded front is a combination of two fronts that form when a cold front catches up and overtakes a warm front.

#### When a cold air mass catches up to a warm air mass is called a front apex?

Stationary fronts bring long rainy periods that stay in one spot. Cold fronts move faster than warm fronts, and sometimes a cold front catches up to a warm front. When this happens, it’s called an occluded 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.

What happens when warm air rises?

If warm moist air rises, it will expand and cool. As it cools, the relative humidity will increase and water will condense. It can then fall back to the earth as precipitation. As air rises, it expands because there is less atmospheric pressure at higher altitudes.

## What happens when warm air rises over cold air?

Warm fronts occur when light, warm air meets cold air. The warm air rises gradually over the cold air as they meet. As the warm air rises it cools and condenses to form clouds. As the warm air rises much faster it may cool more rapidly and may form large cumulonimbus clouds.

### What happens when a warm air mass replaces a cold air mass?

A warm weather front is defined as the changeover region where a warm air mass is replacing a cold air mass. Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.

#### What is cold air mass?

Arctic, Antarctic, and polar air masses are cold. The qualities of arctic air are developed over ice and snow-covered ground. Arctic air is deeply cold, colder than polar air masses.

Why does warm air rise over cold air?

As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.

Why does a warm air mass rise above a cold air mass?

Weather fronts are border zones where masses of air of different temperatures and humidity (moisture) levels meet and push into one another. Warm air is less dense, or lighter, than cold air, and so it rises above the cold air.

## What happens when a cold front catches up to a warm front?

An occluded front develops when a cold front catches a warm front. This forms an occluded front, which is the boundary that separates the new cold air mass (to the west) from the older cool air mass already in place north of the warm front.

### What is warm air mass?

[′wȯrm ¦er ′mas] (meteorology) An air mass that is warmer than the surrounding air; an implication that the air mass is warmer than the surface over which it is moving.

#### What happens when a warm air mass overtakes a cold air mass?

Warm fronts form when a large mass of warm air takes over a cooler air mass. It will cause THICK clouds and rain that may last one or two days. Click to see full answer. In this manner, when a warm air mass overtakes a cold air mass? Warm front Forms when a moist, warm air mass slides up and over a cold air mass.

When a cold front catches up to a warm front?

Occluded fronts form when a cold front catches up to a warm front because cold fronts move along much faster than warm fronts do. The cold front over takes the warm front and cold air moves into cooler air ahead of the warm front. When a warm air mass is trapped between two cooler air masses it is called?

What is the boundary between two warm air masses called?

When a warm air mass moves into an area of cooler air, the boundary between the air masses is called a warm front. The warmer, less-dense air slides up over the cooler, denser air in a wide, gentle slope.
