Occluded Front when a cold front overtakes a warm front
As the storm intensifies, the cold front rotates around the storm and catches the warm front.
occluded front"(Commonly called occlusion; also called frontal occlusion.) A front that forms as a cyclone moves deeper into colder air. This front will separate air behind the cold front from air ahead of the warm front.
Occluded Front
A composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front.

A composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front.
Occluded Front (Occlusion): A complex frontal system that ideally forms when a cold front overtakes a warm front. When the air is colder than the air ahead of it, the front is called a Cold Occlusion.
Occluded Front - the front formed by a cold front overtaking a warm or stationary front and lifting the warm air above the earth's surface ...
OCCLUDED FRONT
Also known as an occlusion, it is a complex front formed when a cold front overtakes a warm front. It develops when three thermally different air masses conflict.
Occluded Front
An area where warm air is pushed upwards as a cold front overtakes a warm front and pushes underneath it

occluded front: when a cold front overtakes a warm front, and three air masses with different temperatures conflict. The resulting frontal boundary type will depend on how they meet.
orographic: weather phenomena caused by mountains.
OCCLUDED FRONT- The lifting of one front by another.
OMEGA FORCING- This is in reference to Q-G theory (Quasi-Geostrophic theory). The omega equation states vertical motion is a function of differential vorticity advection and thermal advection.
Occluded front A front formed when a cold front overtakes and merges with a warm front; represents the final stage in the life cycle of a midlatitude cyclone.
Orographic lifting The forced rising of air up the slopes of a hill or mountain.
Occluded Front - A combination of two fronts that forms when a cold front catches up to and overtakes a warm front.
Occluded Fronts
1. There are 2 types of Occluded Fronts. Cold Air Occlusion and Warm Air Occlusion.
2. Occluded means to close or come together.
Occluded front - a situation where a cold front rams a warm front from behind, as cold fronts are faster.
Trowal - Trough of Warm Air Aloft. An occluded front where cold air is on both sides and the warm air has been completely lifted.
OCCLUDED FRONT: A composite of two fronts that usually occurs when a cold front overtakes a warm front.
OVERCAST: Sky condition when greater than 9/10 of the sky is covered by clouds.
Occluded Front- A boundary between cold and warm air masses that acts like a cold front in some areas and a warm front in others.
Orographic Lifting- The upward flowing of air caused by rising terrain, such as a mountain range.
Occluded Front
Formed in the latter stages of the life of a depression. The cold front associated with the depression moves more quickly than the preceding warming front and after catching it up lifts the warm air above the surface.
Occlusion or Occluded Front: Situation in which the cold front reaches the warm front. Subsequently, the warm sector rises above the surface of the Earth.
Cold-Type Occluded Front - A front that forms when the air behind the cold front is colder than the air underlying the warm front it is overtaking.

COLD HIGH
A high pressure system that has its coldest temperatures at or near the center of circulation, and horizontally, is thermally barotropic.
The basic frontal types are cold fronts, warm fronts and occluded fronts.FrostThe formation of thin ice crystals on the ground or other surfaces.
See occluded front and cold front. WARM HIGH A high pressure system that has its warmest temperatures at or near the center of circulation. Contrast with a cold high. Examples include a cut-off high and an omega block.
Occluded fronts: are formed where a slower moving warm front is followed by a more rapidly moving cold front. The wedge shaped cold front eventually overtakes the warm front and pushes it aloft.
Cold occlusion See Occluded front.
Cold wave A rapid fall in temperature within 24 hours that often requires increased protection for agriculture, industry, commerce, and human activities.
cold front - Any nonoccluded front, or portion thereof, that moves so that the colder air replaces the warmer air; that is, the leading edge of a relatively cold air mass. Compare cold type occlusion.
This sometimes happens when a cold front overtakes a warm front (forming an occluded front), lifting the warmer air away from the surface. It is usually relatively short-lived, but shows up as an unusual layer of warm air on an upper air soundiing.
Warm Front
Any non-occluded front which moves in such a way that warm air replaces cold air.
Water Spout
A spout occurring over water; this behavior is characterized by a tendency to dissipate upon reaching shore.
Cold front Any non-occluded front that moves in such a way so that colder air replaces warmer air; the "leading edge" of a relatively cold air mass.
It is most often used to refer to the point of occlusion of an extratropical cyclone where the cold, warm, and occluded fronts meet. Cyclogenesis may occur at a triple point.
When the cold front moves faster than the warm front, and as it overtakes the warm front, the warm sector is closed and a combine front forms. This process is called occlusion.
The front formed in this way is called an occluded front.

or transition zone between two air masses of different density, and thus (usually) of different temperature. A moving front is named according to the advancing air mass, e.g., cold front if colder air is advancing. See cold front, occluded front, ...
