When a warm air mass and a cold air mass meet?
Likewise, when a warm air mass and a cold air mass meet and neither can move the other the result is an? Warm fronts move slowly and bring warm, humid air. A stationary front forms when cold and warm air masses meet but neither one has enough force to move the other. It maybring many days of clouds and precipitation.
What is air masses?
Science Earth Science Environmental Science Lesson 4 - Air Masses STUDY Flashcards Learn Write Spell Test PLAY Match Gravity Created by lk058 Water and Atmosphere - Chapter 4 - Weather Terms in this set (23) Air Mass A huge body of air that has similar temperature, humidity, and air pressure at a any given height
What type of air mass forms at 50 degrees north latitude?
A warm air mass that forms in the tropics and has low air pressure Polar Air Mass A cold air mass that forms north of 50 degrees north latitude or south of 50 degrees south latitude and has high air pressure Maritime Air Mass a humid air mass that forms over oceans
What is the difference between maritime air mass and continental air mass?
Maritime Air Mass a humid air mass that forms over oceans Continental Air Mass A dry air mass that forms over land Jet Stream bands of high-speed winds about 10 kilometers above Earth's surface Front The boundary where unlike air masses meet but do not mix Occulded Cut off, as in a front where a warm air mass is caught between two cooler air masses
What happens when warm air overtakes cold air?
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 happens to the warm air when it overtakes the cold air quizlet?
The warm air mass overtakes the cold air mass because the warm, less dense air moves over the cold air and gradually replaces it. It is clear and warm when it is gone. The cold, more dense air moves under the warm air mass and pushes it up. This moves fast and it brings thunderstorms, heavy rain, or snow.
What forms when a cool and warm air mass meet?
A stationary front forms when cold and warm air masses meet but neither one has enough force to move the other. It maybring many days of clouds and precipitation. An occluded front forms when a warm air mass is caught between two cooler air masses. The warm air mass is cut ofl or occluded' from the ground.
When a fast moving cold air mass overtakes a slower warm air mass?
Cold front: a fast-moving cold air mass overtakes a warm air mass; the warm air is pushed upward. Warm front: a warm air mass overtakes a slow-moving cold air mass; warm air moves over the cold air.
When a warm air mass and a cold air mass meet and neither can move the other?
stationary frontA stationary front forms when a cold front or warm front stops moving. This happens when two masses of air are pushing against each other, but neither is powerful enough to move the other.
Which front is formed when a cold air mass overtakes a warm air mass What kind of weather does this cause?
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 to the temperature when a warm air mass replaces a cold air mass?
When a warm front passes through, the air becomes noticeably warmer and more humid than it was before. Symbolically, a warm front is represented by a solid line with semicircles pointing towards the colder air and in the direction of movement.
What happens when a warm air mass is caught between two cooler air masses?
a warm air mass is caught between two cooler air masses. Cold air moves under the warm air causing the warm to rise. The temperature drops, clouds form and rain or snow may fall.
What happens when cold air moves under warm air?
forms when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow. After the front passes weather cools and skies become clear.
