Its usually associated with some type of frontal uplift.
Hope this helped!
The pressure if the air around you and if it is High, it causes fair weather.
High pressure usually leads to clam, clear weather.
Stable weather.
Cold air aloft is associated with a surface low pressure system. The reverse is true for warm air aloft. In a baroclinic low pressure system, the upper-level low/trough is usually situated over the cold air, while upper level highs/ridges are around warm air aloft.
A layer of warm air above a layer of cooler air at high altitude.
Not really. Warm air usually has a higher volume than cold air, so its density is usually smaller than that of cold air.
The boundaries between air masses are called front. The types of air mass and movements involved determine the type of front. Warm front: a warm air mass plows into a cold air mass. Cold front: a cold air mass plows into a warm air mass. Stationary front: The warm and cold air masses move little relative to one another. Occluded front: A cold front catches up with a warm front, sending the warm air mass aloft. Dry line: a dry air mass plows into a moist air mass.
When a warm air mass pushes into a cold air mass the result is a warm front, which usually results in rain showers.

When fronts meet from the opposite and collide, it is called an occluded front. A cold occluded front is cold air shoving under cool air at the Earth's surface thus the name 'cold occlusion'. The cold warm air boundary aloft is often west of the surface front. A warm occlusion is when cool air rises over cold air at the surface thus the name 'warm occlusion'. The warm-cold air boundary aloft is often east of the surface front. By Lisa Gardiner

The warm air usually originates from a tropical or subtropical latitude, usually from over a warm body of water such as the Gulf of Mexico.
If the flowing air is warm it heat the air mass and cause this air mass to raise, and if it is cool it makes the air mass cold so it become denser then it descend.michael D.K
A warm front occurs when cooler air retreats and warmer air advances. A cold front occurs when cooler air advances, pushing warmer air away. An occluded front occurs when a cold front catches up with a warm front, sending the warmer air aloft. A stationary front occurs when warm and cold air meet, but neither air mass advances.
When two fronts collide that have about the same temperature, wind might develop. When two fronts collide that have different temperatures, it can lead to a rain storm and sometimes tornadoes.

The warm, moist air involved in tornado formation usually comes from a warm body of water. For the United States it is usually the Gulf of Mexico.
usually in hot or warm temperatures because, hot air expands and cold does not.
