## What is the boundary between 2 air masses called?

Fronts
Fronts are boundaries between air masses. Depending on the air masses involved and which way the fronts move, fronts can be either warm, cold, stationary, or occluded. In the case of a cold front, a colder, denser air mass lifts the warm, moist air ahead of it.

### What happens when the boundary between two air masses stalls?

Boundary between two air masses stalls, the front is called a stationary front. Weather events that cause a damage like hurricanes, tornados, thunderstorms, and blizzards. have warm temperatures, moisture, and rising air maybe supplied by low pressure system and also known as electrical storms.

What causes air masses to move?

Winds and air currents cause air masses to move. Moving air masses cause changes in the weather. A front forms at the boundary between two air masses. Types of fronts include cold, warm, occluded, and stationary fronts.

Do air masses cool as they rise?

The warmer air mass is less dense than the colder air mass. In other words, the warmer air mass is forced to rise over the colder air mass. As air from the warm air mass rises, it cools, leading to the development of clouds and maybe precipitation. Large areas of clouds and precipitation are common near weather fronts.

## What happens when air masses interact?

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 are the 4 types of air masses?

There are four categories for air masses: arctic, tropical, polar and equatorial. Arctic air masses form in the Arctic region and are very cold. Tropical air masses form in low-latitude areas and are moderately warm. Polar air masses take shape in high-latitude regions and are cold.

Why do air masses cool as they rise?

Lifting Along Frontal Boundaries The warmer air mass is less dense than the colder air mass. In other words, the warmer air mass is forced to rise over the colder air mass. As air from the warm air mass rises, it cools, leading to the development of clouds and maybe precipitation.

What causes air masses to rise?

Air masses build when the air stagnates over a region for several days/weeks. To move these huge regions of air, the weather pattern needs to change to allow the air mass to move. One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream.

## What causes air masses to move around?

### What happens when two air masses with large differences in pressure meet?

When two large air masses meet, the boundary that separates them is called a front. Since warm air is less dense and creates less air pressure, it will rise; cold air is denser and creates greater air pressure, and so it will sink.

What are the characteristics of the four main air masses?

Air masses are commonly classified according to four basic source regions with respect to latitude. These are Polar (cold), Arctic (very cold), Equatorial (warm and very moist), and Tropical (warm).

What are the 5 major air masses?

The air masses in and around North America include the continental arctic (cA), maritime polar (mP), maritime tropical (mT), continental tropical (cT), and continental polar (cP) air masses.

## What is the border between two air masses called?

The border between two air masses at the Earth’s surface is called weather front. Air masses are given a two-part name that describes the humidity and temperature characteristics of the region where they form. The first part of an air mass’ name describes its humidity.

### What is the transition zone between two different air masses?

A weather front is a transition zone between two different air masses at the Earth’s surface. Each air mass has unique temperature and humidity characteristics. Often there is turbulence at a front, which is the borderline where two different air masses come together. The turbulence can cause clouds and storms.

What is the meeting place between two air masses?

The Atlas Mountains are the meeting place of two different kinds of air masses—the humid and cold polar air masses that come from the north and the hot and dry tropical air masses that move up from the south. To the influences of altitude and latitude must be added that of aspect or exposure.

What are the boundaries between air masses called?

Fronts the boundaries between air masses. A front is defined as the transition zone between two air masses of different density. Fronts extend not only in the horizontal direction, but in the vertical as well. Therefore, when referring to the frontal surface (or frontal zone), we referring to both the horizontal and vertical components of the front.
