## What is the boundary between two air masses of different temperatures and humidity?

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 is a boundary between two air masses of different density?

Fronts: the boundaries between air masses. A front is defined as the transition zone between two air masses of different density.

#### What forms a boundary between two air masses?

front
Answer and Explanation: The boundary between air masses is called a front. A cold front replaces a warm air mass with a cooler air mass, while a warm front does the opposite.

Is the boundary between two air masses with different characteristics?

Front: The boundary between two air masses of different density. When it does not move, it’s called “stationary”; “warm” when warmer air replaces cooler air; “cold” when cooler air replaces warmer air.

What happens when air masses of different temperatures meet what happens when air masses of different temperatures meet?

When air masses with different temperatures meet, they don’t mix together. Instead a narrow boundary forms between them which is called a front. A front is a narrow boundary between two air masses. Usually when fronts occur one air mass is moving into an area while another is moving out.

## How is the location of an air mass related to its temperature and moisture characteristics?

Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Once formed, air masses migrate within the general circulation. ❑ Upon movement, air masses displace residual air over locations thus changing temperature and humidity characteristics.

### What happens when two different air masses meet?

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 type of weather boundary occurs between a dry air mass and a warm air mass?

What type of weather boundary occurs between a dry air mass and a warm air mass?

When a warm air mass is trapped between two cooler air masses, it is called a/an Occluded front
The boundary between cold and warm air masses is called a/an front

What governs the temperature and humidity of an air mass?

Fronts govern the temperature and humidity of an air mass. 6.

How do air masses affect the temperature of different regions of the earth?

When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. Equatorial air masses develop near the Equator, and are warm.

## When two air masses of different temperatures or moisture content collide One result of this air movement may be?

– The differential heating of air masses and the pressure difference between them causes the winds to blow. Where two air masses of different temperatures and humidity collide, a front is formed. Weather changes occur when two air masses meet along a front.

### How does density relate to cold and warm air masses?

How does density relate to cold and warm air masses? Warm is less dense and cold air is more dense. An air mass is a large body of air that has the same temperature and moisture level throughout.
