Now that we know WHERE the
fronts are, how do we know what
KIND they are?
• It depends on which direction the line you
just drew is moving…
• If colder air is coming in, it is a cold front.
• If warmer air is coming in, it is a warm
So how do I know which way the
front is moving?
• Look at the winds on both sides of the front.
• On one side, the winds will be “pushing”
• On the other side, the winds will be
retreating from the front.
• A pressure center (Low or High) is located
at the “corner” of these two fronts.
• What kind of pressure center is it?
How do you know if it is a cold
or warm front?
• Put yourself in front of the front.
• Ask yourself: “Self, what kind of air am I in
now: warm or cold?”
• Then ask yourself: “Self, what kind of air
will I be in after the front passes?”
• If it got cooler, it is a cold front.
• If it got warmer, it is a warm front.
