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

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

Convergence: When two air masses of the same temperature collide and neither is willing to go back down, the only way to go is up. As the name implies, the two winds converge and rise together in an updraft that often leads to cloud formation.

How does air mass affect weather?

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. This can create a severe storm.

How does the pressure of air masses indicate certain types of weather?

Explanation: A low pressure system is a large mass of air that is rising due to warmer land or water below it. Low pressure systems tend to result in unsettled weather, and may present clouds, high winds, and precipitation. As the low pressure intensifies, storms or hurricanes can be formed.

How would an air mass that formed over the North Pole differ from an air mass that formed over a warm ocean?

An air mass can change as it moves into different environments. For example, if a continental polar air mass moves into warmer areas and over the ocean the air will warm and moisture may evaporate from the ocean surface into the air, adding humidity.

What happens when two air masses meet?

When two air masses meet together, the boundary between the two is called a weather front. 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. Fronts are the main cause of stormy weather.

What happens when two air masses collide and become distorted?

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 2 things that move air masses?


  • An air mass has roughly the same temperature and humidity.
  • Air masses form over regions where the air is stable for a long enough time. The air takes on the characteristics of the region.
  • Air masses move when they are pushed by high level winds.

Which air mass moves in from the ocean?

Air masses that form over the ocean, called maritime air masses, are more humid than those that form over land, called continental air masses.

What is the coldest air mass?

Arctic air masses

When two air masses meet they form a?

So, when two different air masses meet, a boundary is formed. The boundary between two air masses is called a front. Weather at a front is usually cloudy and stormy. There are four different fronts- Cold, Warm, Stationary, and Occluded.

What happens when an air mass moves over a new region?

When an air mass moves over a new region, it shares its temperature and humidity with that region. So the temperature and humidity of a particular location depends partly on the characteristics of the air mass that sits over it. Storms arise if the air mass and the region it moves over have different characteristics.

What contributes to the movement of air masses quizlet?

Air masses are formed by uneven heating and cooling of the Earth by the sun. This causes pressure differences in different areas of the globe. The movement of air masses is just the flow of high pressure air masses to low pressure areas. If the warm air is moist, clouds will form.

What causes air masses to move Brainly?

A change in air temperature creates air pressure differences in the atmosphere. Prevailing winds cause huge air masses, both warm and cool, to move.

What usually keeps two unlike air masses separate when they meet?

When two large air masses meet, the boundary that separates them is called a front, and the properties of air masses are determined by the the underlying surface properties where they originate.

Are high pressure centers of dry air?

Anticyclones are high-pressure centers of dry air. Theyare also called”highsi’Anticyclones lead to dry, clearweather. Because of the Coriolis effect, in the Northern Hemisphere winds spin in a counter- clockwise direction in a cyclone and in a clockrvise direction in an anticyclone.

When two cool air masses meet forces the warm air caught between them upward?

An occluded front develops when two masses of cold air meet. The cold air forces warmer air caught between the two fronts upwards. Cumulonimbus and stratocumulus clouds usually form. Strong winds and heavy rain or snow may result.

What air mass brings extremely cold temperatures and very little moisture?

Continental Arctic

What is the boundary between 2 air masses with different properties called?

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.
