What is a weather front?
A weather front is the boundary between two
different types of air masses (different
temperatures and humidity)
Warm Fronts
If warm or more humid air presses forward and
colder or drier air draws back, the boundary is called
a warm front.
**Warm fronts bring clouds and precipitation**
Cold Fronts
If colder or drier air presses forward and warmer or
more humid air draws back, the boundary is called a
cold front.
**Cold fronts bring storms and large thunderclouds**
Stationary Fronts
When a cold air mass and a warm air mass meet but
are at a standstill, the boundary is called a stationary
front.
**Stationary fronts bring gray skies, rain, or snowy weather that may last a long time **
Occluded Fronts
Sometimes a warm air mass can get caught between
two cold fronts which can force the warm air up into
a wedge shape which is called an occluded front.
**Occluded fronts bring gray skies, rain, or snowy weather that may last a long time **
Warm Front
Cold Front
Stationary Front
Occluded Front
Warm, less-dense air rises gradually above cooler air
Rainy or snowy weather lasts a very long time at this front
Denser, colder air pushes in under warm air
Weather may be drizzly or snowy
Cold and warm air are next to each other, but are at a
standstill
Warm air is forced up in a wedge between two masses
of cold air
This kind of air mass usually brings thunderclouds and
storms
