What happens when a cold front meets a warm front?
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 to the warm air when it overtakes the cold air in a warm front?
At a warm front, a fast-moving warm air mass overtakes a slowly moving cold air mass. Because cold air is denser than warm air, the warm air moves over the cold air. If the warm air is humid, light rain or snow falls along the front. If the warm air is dry, scattered clouds form.
Which type of front occurs when a cold front overtakes a warm front and traps warm air above cold air?
Occluded Fronts The cold occluded front forms when a cold front overtakes a warm front. The warm front rises over the colder, which slowly creeps along the ground surface.
What happens when a cold front meets a warm front quizlet?
When a cold front meets a warm front, and goes under it, the fronts are occluding.
What happens when cold and warm air meet?
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. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.

What type of front results when a fast moving cold air mass overtakes a warm air mass?
Occluded Front 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 warm air collides with cold air and is forced to rise over the cold dome?
An example of lift is warm air colliding with cold air and being forced to rise over the cold dome. The boundary between the warm and cold air masses is called a front. Another example of lift is air flowing up a mountainside.
In which type of front does a warm air mass overtakes a cold air mass?
A warm front moves slower than a cold air mass. The warm raises steadily above the cooler air mass and causes gentle rain showers for longer periods of time. An occluded front is a combination of two fronts that form when a cold front catches up and overtakes a warm front.
What is it called when warm air and cold air 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. This type of front is called a warm front.
When a cold front is approaching what happens quizlet?
Once the front half past, temperatures drop and wind shifts. The weather behind a cold front is dominated by a cold air mass. Weather clears soon after a cold front passes. When a cold front moves over one area low cumulus or stratocumulus clouds may form behind the front.
What kind of front forms when a cold air mass overtakes a warm air mass?
cold front A cold front forms when a cold air mass pushes into a warmer air mass. Cold fronts can produce dramatic changes in the weather. They move fast, up to twice as fast as a warm front.
What kind of extreme weather happens when cold air and warm air collide creating a funnel of air?
Answer and Explanation: The extreme weather that happens when cold air and warm air collide, creating a funnel of air is called a tornado.
What happens after a warm front?
After the warm front passes conditions completely reverse. The atmospheric pressure rises slightly before falling. The temperatures are warmer then they level off. The winds in the northern hemisphere blow south-southwest in the northern hemisphere and north-northwest in the southern hemisphere.
What heat transfer is warm and cold air meeting?
Convection Convection – When warm, moist air near the surface rises to be above the heavier cool, dry air this is a form of heat transfer or convection. The rising motion typically cools the air. As the air cools, it reaches the dewpoint and all of the moisture in the air condenses– forming clouds.
When a cold air mass overtakes a warm air mass?
A cold front forms when a cold air mass pushes into a warmer air mass. Cold fronts can produce dramatic changes in the weather. They move fast, up to twice as fast as a warm front.

What is the result when a warm front is squeezed upward between two cold fronts producing complex precipitation patterns?
What is the result when a warm front is squeezed upward between two cold fronts, producing complex precipitation patterns? The result is a warm front.
What will happen when cold air and warm air meet?
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. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.
Which of the following could result when warm moist air meets cold dry air over land?
As warm moist air mixes with cold dry air. The relative humidity will increase and water will condense. The boundaries between warm moist air and cold dry air is where storms frequently occur.
What happens when a cold front passes?
As the cold front passes in your area, a sudden drop in temperature will occur, with the winds building and shifting. The rain will increase and may contain a mixture of hail, lightening and thunder. Cumulonimbus clouds are common in a passing cold front, with the large clouds extending high into the sky.
What happens after a cold front?
Changing Precipitation The cold front shoves the warmer air ahead of it upward, and as it cools the air discharges its moisture. The upheaval of warm air and the development of cumulonimbus clouds signals thunderstorms with heavy rains, and some strong cells capable of producing heavy downpours.
What type of heat transfer is described as warm air rises and the cold air sinks?
This is called a convection current. Convection currents are defined as room air rising and cold air sinking by the Children's Museum of Houston, on CDM.org.
Is convection heat transferred?
Convection is a very efficient way of heat transfer because it maintains a steep temperature gradient between the body and surrounding air or water. Evolutionary adaptations that prevent or enhance heat convection are important constituents of the mechanisms of thermoregulation.
Which type of front forms when a cold air mass overtakes a warm air mass?
occluded front An occluded front is a combination of two fronts that form when a cold front catches up and overtakes a warm front. The result is a mix of rain showers and thunderstorms. A stationary front is the boundary between two air masses when neither is moving.
What happens at a warm front?
A warm front is defined as the transition zone where a warm air mass is replacing a cold air mass. 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.
What happens when warm front passes?
When a warm front passes, the air becomes noticeably warmer and more humid than it was before. On a weather forecast map, a warm front is represented by a solid line with red semicircles pointing towards the colder air and in the direction of movement.
What happens when a warm front forms?
Light to moderate precipitation in the form of rain, sleet, snow, or drizzle often occurs, along with poor visibility. Since warm air is less dense than cold air, the barometric pressure first falls, rises slightly, and then continues to fall until the warm front passes completely.
