3. How do Warm and Cold Fronts Work?
A Cold Front occurs when colder air advances toward warm air. The cold air goes
under the warm. As the warm air is lifted, The cool water vapor condenses and
this forms clouds. When cold fronts and warm fronts combine, thunderstorms
h
even tornados may happen.

5. How Warm Fronts Affect The Weather
During a warm front, the temperature
starts to get warm very quickly, after
staying warm for a while the warm front
levels out. When the front passes, it will
lightly drizzle but not much else, once it
has passed, it either continues or stops.
The clouds that come with warm fronts
are usually stratus, and after the warm
front passes or it scatters then the warm
front clears. While the front is in an area it
is not windy, but when its gone, the wind
blows north to northwest and south to
southwest.

6. How Cold Fronts Affect The Weather
When a cold front passes the
temperature will drop. After a cold front
passes the temperature levels out. The
wind has the same pattern of a warm
front, it usually blows west to east. A cold
front can cause rain or storms and after it
passes precipitation clears.

7. Why Fronts Move West to East in the
United States
The reason that fronts in the USA move
from west to east is because the fronts are being
pushed by the jet stream, a upper level air current that
blows across the country and carries the fronts and
other weather west to east.
