Weather patterns: air masses and fronts
See how cold and warm fronts, highs and lows bring the weather that comes with them.
Explore
Cold air wedges under warm air and lifts it fast.
Tall clouds build: heavy rain or thunderstorms, then cooler, drier air.
Assumptions
•
An air mass is a huge body of air with about the same temperature and humidity throughout.
•
A front is the boundary where two air masses meet.
•
Cold air is denser than warm air, so it stays low and pushes the warm air up.
