This short Presentation will give you an Introduction to Fronts

1. Cold Front
• A Cold Front is usually known for creating
Thunderstorms. What it does is it takes over the
Warm Air Mass by pushing it. The Cold Front is
like a bulge, because of this it makes Warm Air
violently Rush up into the Atmosphere thus
creating Clouds then Instability, then Rain.
However sometimes there is a Dry Cold Front
which has no Moisture thus creating no Rain.
After a Cold Front passes Temperature are likely
to Cool Down! The Diagram next is a Perfect
example of a Cold Front!

3. Warm Front
• A Warm Front is like a Cold Front but the
Warm Air is Pushing the Cold Air. However a
Warm Front pushes the Warm Air up on a
Slope to the Atmosphere. Usually a few days
before a Warm Front you will see High Cirrus
Clouds then you will start to get thicker &
lower clouds as time passes by. Warm Fronts
are known for creating just rain events or just
Scattered Showers in Areas. The Diagram next
is a Perfect example of a Warm Front!

5. Stationary Fronts
• A Stationary Front is interesting because it is
the Front that creates a Low Pressure System.
You have Warm air moving to the East while
you have Cool air moving to the West. Due to
this it creates a Counter-Clockwise Rotation
creating a Surface or Upper Level Low which
creates Cold Front & Warm Fronts. It is the
main function in the Cycle of the Low Pressure
Systems. The Diagram next is a Perfect
example of a Stationary Front!

7. Occluded Front
• An Occluded Front shows Weakening in a Low
Pressure System. It is when a Cold Front
catches up to a Warm Front. Basically it is a
Cold Front & a Warm Front Combined! The
Diagram next is a Perfect example of a
Occluded Front!
