What does occlusion mean in weather?

Occluded Front: when a cold front overtakes a warm front. . Occluded Front when a cold front overtakes a warm front. A developing cyclone typically has a preceding warm front (the leading edge of a warm moist air mass) and a faster moving cold front (the leading edge of a colder drier air mass wrapping around the storm …

What are the two types of occluded front?

Occluded fronts usually form around mature low pressure areas. There are two types of occlusion, warm and cold: In a cold occlusion, the cold air mass overtaking the warm front is colder than the cool air ahead of the warm front, and plows under both air masses.

What is occlusion geography?

n. (Physical Geography) meteorol the line or plane occurring where the cold front of a depression has overtaken the warm front, raising the warm sector from ground level. Also called: occlusion.

What does a occluded symbol look like?

The symbol for an occluded front is a purple line with alternating triangles and semi-circles (also purple) pointing in the direction the front is moving. Sometimes a cold front will “catch up” to a warm front and overtake both it and the cooler air out ahead of it.

When does an occluded front form in the weather?

In meteorology, an occluded front is a weather front formed during the process of cyclogenesis when a cold front overtakes a warm front.

What’s the difference between warm and cold occlusion?

There are two types of occlusion, warm and cold: In a cold occlusion, the cold air mass overtaking the warm front is colder than the cool air ahead of the warm front, and plows under both air masses. In a warm occlusion, the cold air mass overtaking the warm front is warmer than the cool air ahead of the warm front,…

What is the medical definition of ostial defects?

Where does the occluded front meet in a cyclone?

Occluded front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth ‘s surface. The point where the warm front and the occluded front meet (and consequently the nearest location of warm air to the center of the cyclone) is called the triple point.
