Occlusion
A frontal system which forms when a cold front overtakes a warm front. When the air behind the front is cooler than the air ahead, it is called a cold occlusion, when the air ahead is milder, it is a warm occlusion.

occlusion"1. (Or frontal occlusion.) In meteorology, the process of formation of an occluded front.
occlusion—Same as occluded front.
occluded front (commonly called occlusion, also called frontal occlusion)—A composite of two fronts as a cold front overtakes a warm front or quasi-stationary front.

A frontal zone formed when a cold front overtakes a warm front and, finding colder air ahead of the warm front, leaves the ground and rises up and over this denser air.
Warm Occlusion
A frontal zone formed when a cold front overtakes a warm front and, finding colder air ahead of the warm front, leaves the ground and rises up and over this denser air. Compare with cold occlusion.

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.
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.
Occlusion
The end result of a cold front overtaking a warm front. It marks the dying stages in the life of a low.

OCCLUSION - The overunning of one weather system over another. May also be called STACKING when used with low pressure systems at different altitudes. More commonly used when two weather fronts meet and one front rides up and over the other.

Warm Core Weather Systems: Weather systems with the air at their center warmer than the surrounding air.
Warm Front: When warm air replaces cold air.

Cold-type occlusion A front formed when a cold front overtakes a warm front and the air behind the front is colder than the air ahead of the 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 (Occlusion) A composite of two fronts formed as a cold front overtakes a warm front. A cold occlusion results when the coldest air is behind the cold front.
Two types of occlusions can form depending on the relative coldness of the air behind the cold front to the air ahead of the warm or stationary front.
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.
The subsequent occlusion will usually carry the letter previously ascribed to the warm front (in this case 'A').
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. The type of frontal boundary they create depends on the manner in which they meet.
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.
We have superimposed inflow and RFD outflow arrows on these two slides, again to emphasize the advance of the RFD and the eventual occlusion of the gust front.

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.

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.
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. The amalgamation of the cold and warm fronts produce the Occlusion or Occluded front ...
