What is a cold front?

• front when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow)

• The temperature at which condensation begins

• very cold, very dry stable air mass

• A boundary between air masses that don't move possibly causing rain for several days

What is a stationary Front?

• unstable cold, moist air mass that forms over cold oceans--

  Winter and Summer- cold and humid

• very cold, very dry stable air mass

• unstable, warm, dry air mass that forms over land

  Winter - warm and dry

  Summer - Hot and dry

• A boundary between air masses that don't move possibly causing rain for several days

What is an occluded front?

• brings cool temperatures

• a front where a warm air mass is caught between two colder air masses

• Brings clear weather

• brings drizzly rain

• brings large amounts of rain and snow

What is an air mass?

• When any two air masses meet. The four major types are cold fronts, warm fronts, stationary fronts, and occluded fronts.

• A huge body of air that has similar temperature, humidity, and air pressure at any given height
