When cold air moves toward warm air, it pushes the warm air upward because cold air is denser and therefore heavier than warm air. This creates a lifting mechanism known as cold air advection, which can lead to the formation of clouds and precipitation.

When warm air pushes into cold air the result is a warm front.

A cold front forms when a cold air mass moves into and displaces a warm air mass. As the dense cold air pushes the warm air up, it creates a boundary known as a cold front. This usually leads to showers and thunderstorms along the front.
This is typically a cold front. As the cold air mass moves under the warm air mass, it pushes the warm air upwards, where it condensates and creates precipitation.
Precipitation usually occurs along and just ahead of a cold front due to the lifting of warm, moist air. As the cold front moves in, it pushes the warm air up, causing it to cool and condense into precipitation.
Cold fronts typically move faster than warm fronts because cold air is denser and pushes warm air more quickly. Cold fronts can bring quick changes in weather conditions, such as thunderstorms, whereas warm fronts bring more gradual weather changes like prolonged periods of precipitation.
A cold front forms when a cold air mass advances and replaces a warmer air mass. As the cold air moves into an area previously occupied by warm air, it pushes the warm air upward, creating instability and potentially leading to the development of thunderstorms and other severe weather.
