What do you call two air masses that collide?
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 it called when a warm and cold fronts meet?
An occluded front forms when a cold front reaches a warm front, forcing all the warm air to rise to higher altitudes and the cold air is stratified near the ground.
What happens when two 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 happens when two wind fronts converge?
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.
What happens when two air masses collide quizlet?
What happens when two air masses meet? When two air masses meet, they form a front, which is a boundary that separates two air masses of different properties. How is a warm front produced? A warm front forms when warm air moves into an area formerly covered by cooler air.
What happens when two air masses meet quizlet?
What happens when two air masses meet? When two air masses meet, they form a front, which is a boundary that separates two air masses of different properties. How is a warm front produced? A warm front forms when warm air moves into an area formerly covered by cooler air.
What might happen when two air masses come together and form a warm front?
As the warm front approaches, there may be fog or increasing rainfall, and thunderstorms may form, as well. This is due to the (usually) higher humidity in the air of warm fronts compared to that of cold fronts.
What is a convergence of air?
Air moving in toward a center of low pressure or a trough is forced to rise, exhibiting a motion called convergence. Similarly, air moving outward from a ridge or center of high pressure descends, exhibiting divergence.
When two air masses meet they form a front which is a boundary that separates two air masses of different properties?
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 with different properties meet quizlet?
What happens when two air masses meet? When two air masses meet, they form a front, which is a boundary that separates two air masses of different properties.
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 is it called when winds meet from two directions resulting in air being forced upwards?
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.
What is mass convergence?
Mass convergence is found in areas where winds come together. As winds come together, mass builds up and therefore causes air to rise, creating an updraft. Convergence may occur due to topography or daytime heating, and can be especially strong along fronts and dry lines.
What is divergence and convergence?
Divergence generally means two things are moving apart while convergence implies that two forces are moving together. In the world of economics, finance, and trading, divergence and convergence are terms used to describe the directional relationship of two trends, prices, or indicators.
What forms when two air masses meet and creates weather?
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 is converging air?
Convergence in a horizontal wind field indicates that more air is entering a given area than is leaving at that level. To compensate for the resulting "excess," vertical motion may result: upward forcing if convergence is at low levels, or downward forcing (subsidence) if convergence is at high levels.
What is wind convergence?
As you know, a strong wind moving into a weak wind is convergence. Second, as height contours spread apart, a divergence of air occurs. The convergence due to stronger wind moving into weaker wind replenishes the mass lost due to the divergence in the diffluent flow.
What happens when two 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.
