FRONTS
1. An Air Mass is:
a. A ______________________________________ that has similar
_________________________________________ and
___________________________________________ throughout.
b. An air mass gets its temperature and moisture from
_____________________________________________________________
(For example: any air mass that develops over the Gulf of Mexico will be
warm and wet because the Gulf of Mexico is warm and wet).
2. A Front is:
a. Air masses with different temperatures do not usually
________________________________.
b. Therefore, when two different air masses meet, a
____________________________________________ forms between them
3. There are four main types of fronts: (List)
4. Cold Front:
a. _____________________________________________
a warm air mass (moves under the warm
air, pushing it up).
b. Cold fronts can move fast, producing
_____________________________________________
__________________________________. Cooler
weather usually follows a cold front
because the warm air is pushed away from the Earth’s surface.
5. Warm Front:
a. ___________________________________________
______________________ a cold air mass (warm
air moves over cold air and replaces it).
b. Warm fronts generally bring
___________________________________________.
After the front passes, weather conditions are __________________________________.
6. Occluded Front:
a. A _________________________________________
overtakes a slower-moving warm air
mass and forces the warm air up. The
cold air keeps moving until it meets
another cold air mass. Leads to cool
temperatures and lots of precipitation.
7. Stationary Front:
a. A cold air mass meets a warm air mass, but
_________________________________. Usually
__________________________________________________
are found.
