Flashcards
Cold Front
Cold Front
Forms when cold, dense air pushes under warm, lighter air, forcing the warm air to rise and often causing rain or thunderstorms.
Warm Front
Warm Front
Forms when a warm air mass pushes into a cooler air mass, often bringing stormy weather as the warm air rises and condenses.
Occluded Front
Occluded Front
A front formed when a warm air mass is caught between two cold air masses. The warm air rises as the cool air masses push and meet.

Study Notes
- Weather fronts are boundaries between air masses that can lead to various weather conditions.
Cold Fronts
- Occur when a cold, dense air mass pushes under a warm, lighter air mass.
- The warm air is forced to rise.
- The advancing cold air replaces the warm air at the surface.
- Rising moisture in the warm air mass cools and condenses, potentially forming rain and thunderstorms.
Warm Fronts
- Occur when a warm air mass pushes into a cooler air mass.
- Stormy weather can result as the warm air rises above the cool air mass, forming clouds and storms.
Occluded Fronts
- Occur when a warm air mass gets caught between two cold air masses.
- As the cold air masses push and meet, the warm air mass rises, becoming cut off from the ground (occluded).
- A temperature drop results.
Stationary Fronts
- Form when a cold or warm front stops moving usually when two air masses are pushing against each other, but neither is strong enough to move the other.
- Parallel winds can help them stay in place.
- They bring long-lasting precipitation.
- A boundary is created where two air masses (one warm, one cold) are in stalemate.
- Stagnation leads to persistent moisture convergence, cloud formation, and extended periods of rain, snow, or drizzle.
