Air Mass

• An area of cooler air that causes happy high-pressure weather

• An area of warmer air that causes lousy low-pressure weather

• Strong, rapid air currents that form high in the atmosphere

• A large body of air that has uniform properties, such as a consistent temperature or humidity, based on the region the air mass forms in

Occluded Front

• Moves slowly because neither the cold nor warm front has enough power to push the other out of the way. These fronts bring many days of cloudy, wet weather

•  Moves quickly and brings thunderstorms, heavy rain, or snow followed by cooler and drier weather

• Moves slowly and brings many days of drizzly rain followed by clear and warm weather

• When a faster-moving cold front overtakes a slower-moving warm front with enough force, it will cause severe weather and large amounts of precipitation
