​Do Now: Scenario:You are a meteorologist predicting the weather.
1. There is a cP air mass moving in from canada. What is the humidity and temperature of this air mass?
Humidity: ___________________
Temperature: ________________

2. There is another air mass moving in from the Gulf of Mexico. What would be the humidity and temperature and weather symbol for this air mass?
Humidity: ____________________
Temperature: _________________
Weather map symbol: __________

3. If these two air masses meet in the middle of the United States, predict what conditions might occur as a meteorologist.

Multiple Choice

Why don't different air masses mix easily?

1
Because they are all the same
2
Due to the lack of wind
3
Because they are too far apart
4
Different air masses have different densities, temperatures, and moisture content.

8

1.Why don’t different air masses easily mix? 

Different air masses don’t easily mix because they have different densities

2. Explain what happens along the edge of a front when the two air masses meet?


When two air masses meet at the front they don't mix so one has to rise. This leads to cloud formation, precipitation, possible thunderstorms and other severe weather



3. How does the strength of the temperature difference between air masses affects the winds at fronts? 

The stronger the temperature difference between the air masses, the stronger the winds will be.
