    • Air Masses and Weather Fronts
    • Air Masses
      • EQ: How do meteorologists use air masses and weather fronts to predict our weather?
    • Warm Up
      • Think back to the recent snow storm we had where we were out of school for one week.
      • Which type of air mass do you think caused the snow and why do you think this way?
      • http://www.weatherquestions.com/What_is_an_air_mass.htm
      An air mass is a large body of air with similar temperature, pressure, and humidity levels throughout.
    • Air Masses
      • Get their properties from spending many days, even weeks, over the same area.
        • Example: If an air mass sits over an ocean for awhile, it becomes humid .
        • If an air mass sits over land , it becomes dry.
    • Air Masses
      • Four types of air masses
        • Maritime
        • Continental
        • Polar
        • Tropical
    • Air Masses
      • Continental
      • Maritime
      • Form over land and are dry
      • Form over water and are moist
    • Air Masses
      • Tropical
      • Form over the tropics (low latitudes)
      • Warm/Hot
      • Polar
      • Form at the polar regions of Earth (high latitudes)
      • Cool/Cold
    • Air masses
      • Why does our weather change?
      • Air masses move!
      • How?
      • Global winds push air masses around the Earth!
    • Air Masses Reflect
      • M- Describe the four types of air masses.
      • I- If you could become an air mass, which would you be and why?
      • U- Look back at the warm up question. Do you agree with your answer? Support your answer with details.
      • S- Create a flag for an air mass and explain why you chose that air mass.
    • Fronts
      • A front is a place where two different air masses meet
      • Three main types
      • A “battle” between air masses
      Continental Polar Maritime Tropical FRONT
    • Cold Fronts
      • Click for Animation
    • Cold Front
      • Moves quickly and can produce thunderstorms
      • After it moves through, skies will be clear and temperatures will be cooler
    • Cold Front Reflect
      • M- Explain the types of weather associated with a cold front.
      • I- Act out a cold front with a partner.
      • U- A cold front passed through last night. Predict what the weather is like now?
      • S- Create a metaphor: A cold front is
      • like a _______________________. Explain.
    • Warm Front
      • Click for Animation
    • Warm Front
      • Moves slower than cold fronts
      • Brings humid weather and sometimes rains for days
      • After it moves through, temperatures are warmer
    • Warm Front Reflect
      • M- Restate the cause of a warm front.
      • I- Which type of front do you feel is the best and why?
      • U- Compare and contrast warm fronts and cold fronts.
      • S- What would it be like to be a warm front?
    • Stationary Front
      • Click for Animation
    • Stationary Fronts
      • Two air masses next to each other, but neither moves.
      • Weather remains the same for days
    • Stationary Front Reflect
      • M- Summarize the three types of fronts.
      • I- You are charged with studying the effects of air masses and fronts. How would you do it?
      • U-Which type of front do you think is the most destructive and why?
      • S- Imagine you live in a world with only two types of air masses. How would that effect fronts?
    • Become the meteorologist!
      • Use the weather map given to you and what you have learned about air masses and fronts and predict the weather for _______, _______,________,_______. Be sure to include an appropriate temperature and sky conditions (cloudy, sunny, raining, snowing, etc.)
