  • This presentation is intended to introduce or
    review material. The student will identify each
    type of front on a weather map using their
    symbols, determine which way the front is moving,
    and predict relative temperature using a weather
    map.

3
Air Mass
  • A large body of air with similar temperature and
    moisture.
  • Air masses form over large land or water masses.

4
Frontal Boundaries
  • Where air masses interact also know as a front.
  • 4 kinds of fronts
  • Cold front
  • Warm front
  • Occluded front
  • Stationary front

5
Cold Front
Back to activity
  • A cold air mass is replacing a warmer air mass.
  • Shown on a weather map by a blue line with
    triangles pointing the direction the cool air is
    moving.

6
Warm Front
Back to activity
  • Warm air mass replacing a cooler air mass.
  • Shown on a weather map by a red line with half
    circles pointing the direction the warm air is
    moving.

7
Comparing Warm and Cold Fronts
  • Cold fronts move faster than warm fronts.
  • The weather activity in a cold front is often
    violent and happens directly at the front.
  • Cold fronts have sudden gusty winds high in the
    air creating turbulence.
  • The weather activity in a warm front generally
    happens before the front passes.
  • In a warm front the cloud formation is very low
    often creating situations of poor visibility.

8
Occluded Fronts
  • When a warm front is trapped by 2 cold fronts.
  • Shown on a weather map by a purple line with
    alternating triangles and semicircles pointing
    the direction the front is moving.

Back to activity
9
Stationary Fronts
Back to activity
  • A front that stops moving or is moving very
    slowly.
  • Shown on a weather map with alternating red
    semicircles pointing away from the warm air and
    blue triangles pointing away from the cold air.

Be a Weather Forecaster
You are planning to travel to Alabama in 2 days.
The high temperature there for today is 68º F.
Use the map to help you predict whether the
temperature in Alabama will increase, decrease,
or stay the same. Explain why you think so.
16
Be a Weather Forecaster
There is a cold front approaching. The
temperatures will probably be cooler behind the
front.
17
Be a Weather Forecaster
  • Of course, meteorologists (weather forecasters)
    use much more data than fronts and air masses to
    help them forecast the weather more accurately.
    But any forecast is just a prediction of what
    might happen. Even with the best data, weather
    forecasts can be wrong.
