* Air Masses: Large bodies of air with relatively uniform temperature and humidity.

* Fronts: The boundary between two different air masses.

Types of Fronts:

* Cold Front: A cold air mass pushes into a warmer air mass. This can lead to:

* Rapid temperature drops

* Strong winds

* Heavy precipitation

* Thunderstorms

* Warm Front: A warm air mass moves over a colder air mass. This can cause:

* Gradual temperature increases

* Light to moderate precipitation

* Fog

* Stationary Front: Two air masses meet but neither is strong enough to displace the other. This can result in:

* Persistent precipitation

* Cloudy skies

* Occluded Front: A cold front overtakes a warm front, forcing the warm air aloft. This can lead to:

* Complex weather patterns

* Heavy precipitation

Important Notes:

* The interaction of air masses and fronts is a key factor in determining weather patterns.

* The specific weather associated with a front depends on the temperature difference between the air masses and other factors.

* Front movement and interactions are dynamic and constantly changing.
