When a fast moving cold air mass collides into a warm air mass.
Occluded Front
A stationery front. A cold front is where cold air gains over warm air. Warm front is where warm air gains over cold air. An Occluded front is where warm air is pushed up and cold aair over takes at lower levels.
Occluded front
It is cold.
Stationary Front
As warm air is lifted over advancing cold air, itself cooled as its pushed away from gravity's pull at the Earth's surface, the water will begin to condense into clouds and precipitation will form, usually of the "showers and thunderstorms" variety.
Yes, because the warm air is always less dense, so it rises over the cold front.

That's called an 'occluded' front.

Air masses that are cold and forms over polar regions is polar. A cold front occurs when a cold air mass meets and displaces a warm air mass. A front that forms when a warm air mass is trapped between cold air masses and forced to rise is called a occluded front.
