Front name
AND
Symbol
Description of the front
The type of
weather caused by
the front
Cold Front
Cold air moves quickly
underneath warm air,
forcing the warm air to
rise.
This forms a narrow
band of violent
storms.
Warm Front
Warm air slides over
cool air that is leaving.
This forms feathery
clouds.
There may also be
light showers.
Occluded Front
Two cool air masses
meet and push up
warmer air.
This causes strong
winds and heavy
precipitation.
Stationary Front
A cool air mass and a
warm air mass meet
and stop moving
(neither one advances).
This causes a few
days of light
rain(drizzle) and
windy weather.
