Presentation transcript:

Air Mass (visual organizer) large body of air where temperature and moisture are similar throughout moist (m=maritime) or dry (c=continental) warm (T=tropical) or cold (P=polar) 4 types of air masses: mT, mP, cT, cP

4 types of air masses

4 types of FRONTS —where 2 air masses meet (do not mix well due to different densities) cold front cold air moves under warm air and pushes the warm air up can move quickly and bring thunderstorms brings cooler air warm front warm air moves over colder/denser air usually brings drizzle followed by warm temperatures

4 types of FRONTS —continued occluded front warm air mass trapped between 2 colder air masses brings cooler temperatures and lots of precip stationary front often brings many days of cloudy, wet weather could lead to floods

Math Skills A cold front is moving toward the town of La Porte at 35 km/h. The front is 200 km away from La Porte. How long will it take the front to get to La Porte? 5.7 hours Meteorologists compare a new weather map with one that is 24 hours old.
