What is the transition between two air masses called?
Fronts 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.
What is it called when two air masses meet and stop moving?
Stationary Fronts Sometimes two air masses stop moving when they meet. These stalled air masses create a stationary front. Such a front may bring clouds and precipitation to the same area for many days.
What forms when two air masses meet and creates weather?
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 2 fronts collide?
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 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 fronts 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 is Frontogenesis and frontolysis?
Frontogenesis refers to the initial formation of a surface front or frontal zone, while frontolysis is the dissipation or weakening of a front.
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 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 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 weather fronts meet?
Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together.
What happens when 2 air masses collide?
When two different air masses collide, they don't mix. They push against each other along a line called air front. When a warm air mass meets a cold air mass, the warm air rises as it is lighter and the water vapour in it condenses at higher altitudes.
What is the meaning of frontolysis?
Definition of frontolysis : a process tending to destroy a meteorological front.
What is frontolysis in geography?
Frontolysis in meteorology, is the dissipation or weakening of an atmospheric front. In contrary to areas of "Frontogenesis", the areas where air masses diverge are called areas of frontolysis.
What occurs at a front when two air masses meet?
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 happens when two air masses meet the warm air will?
When a moving cold air mass meets a warm air mass, that is lighter, it tends to wedge below the latter, thus giving origin to a cold front. The warm air is forced upwards and its ascent causes the formation of clouds.
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 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 is Frontogenesis and Frontolysis?
Frontogenesis refers to the initial formation of a surface front or frontal zone, while frontolysis is the dissipation or weakening of a front.
What occluded front?
An Occluded Front forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward.
What is frontogenesis and Frontolysis?
Frontogenesis refers to the initial formation of a surface front or frontal zone, while frontolysis is the dissipation or weakening of a front.
What is occlusion in geography?
In meteorology, an occluded front is a type of weather front formed during cyclogenesis. The classical and usual view of an occluded front is that it initiates when a cold front overtakes a warm front near a cyclone, such that the warm air is separated (occluded) from the cyclone center at the surface.
What happens when 2 low pressure systems collide?
This collision course creates increased wind and fronts and as the pressure systems overlap, clouds will begin to form and potentially rain will fall.
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 a triple point in weather?
Triple Point The intersection point between two boundaries (dry line, outflow boundary, cold front, etc.), often a focus for thunderstorm development.
What is an Occulation?
An occlusion is a complete or partial blockage of a blood vessel. While occlusions can happen in both veins and arteries, the more serious ones occur in the arteries. An occlusion can reduce or even stop the flow of oxygen-rich blood to downstream vital tissues like the heart, brain, or extremities.
Why is it called Fujiwhara effect?
The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one.
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.
Can water exist in all three states at the same time?
At low pressure, steam, water and ice can all occupy the same container simultaneously. The combination of temperature and pressure is called the "triple point" of a substance. In this state, all three forms of water are in thermodynamic equilibrium — the amounts of each phase remain unchanged.
