Weather Fronts
A weather front is the bound-ary
between two air masses.
When a front passes over an area,
temperature, wind speed, wind di-rections,
atmospheric pressure and
precipitation levels can change.
There are three types of fronts:
cold, warm and stationary.
A cold front is when cold air is
replacing warm air at the surface.
Cold fronts tend to move fast and
are associated with violent weather.
Cold fronts usually bring cooler
weather, clearing skies and a sharp
change in wind direction.
A warm front is when warm air
replaces cooler air at the surface.
Warm fronts tend to move slowly
and are likely to bring light to mod-erate
continuous rain.
Clear skies and humid air usually
follow warm fronts. photo taken from http://www.dreamworksfansite.com/
