Predicting the WeatherFronts
Fronts
What do you think a Front is? How do you think Fronts form and how do they affect the weather?
TURN AND TALK to discuss, then share answers as a class.
Fronts
Weather maps not only show air masses but they show fronts as well.
A front is a place where two different air masses meet.
Fronts - draw the pictures in your notebook
Triangles show a cold front
Half circles show a warm front
The triangles and half circles point in the direction in which the front is moving.
Fronts
At a cold front, a cold air mass bumps against a warm air mass. Strong storms happen at cold fronts.Thunderstorms are likely in warm weather. In winter, snowstorms are likely.When a cold front passes over an area, the temperature drops.
Fronts
At a warm front, a warm air mass meets a colder air mass and slowly rises over it. Stratus clouds form at warm fronts. They often bring rain.
After a warm front passes over an area, the temperature rises.
Fronts
A stationary front forms when two air masses meet and stop moving.
Stationary fronts bring clouds and precipitation, sometimes lasting for several days.
