What happens when two air masses of different temperatures 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. As air masses move, pushed by winds, they directly influence the weather in the regions over which they pass.
What take place when air masses of two extremely different temperatures come together?
When two air masses come together, but neither displaces the other, the boundary between them is referred to as a stationary front. These fronts bring precipitation for several days. This causes the cold air mass to move under the warm air mass if they meet. Cold air is heavier than warm air.
What would happen if there was a large temperature difference between the two air masses?
If the lifted air is moist, there will be condensation and precipitation. Winds are common at a front. The greater the temperature difference between the two air masses, the stronger the winds will be. Fronts are the main cause of stormy weather.
What causes air masses to have different temperatures?
Air masses are slowly pushed along by high-level winds. 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.
What happens when two air masses meet quizlet?
When two air masses meet, they form a front, which is a boundary that separates two air masses of different properties. When a cold front overtakes a warm front, an occluded front forms.
What happens when two winds collide?
In a warm front, a warm air mass moves into a cold air mass. 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 air masses of different temperatures meet quizlet?
What happens when air masses of different temperatures meet? Surface winds move counterclockwise. The entire cyclone moves from west to east. The cold front advances faster than the center of the storm, and the warm front advances more slowly than the center.
When two air masses collide air is forced upward?
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 to the warm air when it overtakes the cold air?
When a warm air mass meets and overrides a cold air mass, a warm front forms. The warm air moves up and over the cold and generally brings drizzly precipitation. If a fast-moving cold air mass overtakes a slower-moving warm front and then continues advancing and catches another cold front, an occluded front forms.
What happens when a cold air mass meets a warm air mass quizlet?
the two air masses move under the warm front pushing it up. cool temperatures and large amounts of rain or snow. forms when a cold air mass meets a warm air mass. as the air in the center of the cyclone rises, it cools and forms clouds and rain.
What happens when warm front passes?
Warm fronts generally move from southwest to northeast and the air behind a warm front is warmer and more moist than the air ahead of it. When a warm front passes through, the air becomes noticeably warmer and more humid than it was before.
What happens when there are extreme differences in air pressure and temperature?
When there are extreme differences in air pressure and temperatures, violent storms often occur, including hailstorms and tornadoes. Tornadoes form when warm moist air is lifted, causing an updraft. Moisture condenses into clouds and forms a thunderstorm.
