What front usually happens and is over quickly?

What front usually happens and is over quickly?

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.

When two different large air masses meet what is formed?

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 is a boundary that separates two different air masses called?

Front: The boundary between two air masses of different density. When it does not move, it’s called “stationary”; “warm” when warmer air replaces cooler air; “cold” when cooler air replaces warmer air.

What are the symbols for different fronts?

Symbols are used on surface weather maps to indicate the characteristics or type of front.

• A stationary front line is indicated by blue triangles on one side of the line alternating with red semi-circles on the opposite side of the line.
• A cold front is a front that is moving in the direction of the warmer air.

What direction does a cold front move?

Cold Front: transition zone from warm air to cold air. A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.

What weather does an occluded front bring?

An Occluded Front forms when a warm air mass gets caught between two cold air masses. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation. Occluded fronts usually form around mature low pressure areas.
