Which front type would cause the air to rise up more quickly?

Cold Front Cold fronts can produce dramatic changes in the weather. They move fast, up to twice as fast as a warm front. As a cold front moves into an area, the heavier (more dense) cool air pushes under the lighter (less dense) warm air, causing it to rise up into the troposphere.

What happens when air mass moves rapidly upward?

On the other hand, when a cold air mass catches up with a warm air mass, the cold air slides under the warm air and pushes it upward. As it rises, the warm air cools rapidly. This configuration, called a cold front, gives rise to cumulonimbus clouds, often associated with heavy precipitation and storms.

What kind of air rises faster?

The cold air undercuts the warmer air in front of it, forcing the warm air to rise above it more vigorously than at a warm front. As the warm air rises much faster it may cool more rapidly and may form large cumulonimbus clouds.

What do we call a strong current of air that moves between polar and tropical air masses?

Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere. An air current is a flowing movement of air within a larger body of air.

What kind of air rises faster hot or cold?

Hot air rises because it is less dense than cold air, so air will rise above a heater and sink near a cold window. Forced convection refers to fluids being pushed around by outside forces. A fan or a pump are forms of forced convection, which is very useful for moving heat from one place to another.

What causes an air mass to have a high pressure?

High pressure areas are usually caused by air masses being cooled, either from below (for instance, the subtropical high pressure zones that form over relatively cool ocean waters to the west of Califormia, Africa, and South America), or from above as infrared cooling of winter air masses over land exceeds the warming …
