between wind and waves?

(the stronger the wind,
the bigger the waves)

4. Is air rising or sinking Is air rising or sinking
at the equator?
Is air rising or sinking
at 30°N?

5. An air mass is a large body of air with similar characteristics
Air Masses and Fronts
An air mass is a large body of air with similar characteristics
throughout

6. Air masses are classified based on their
and amount of
temperature
moisture
Air masses get their properties based on
Where they form

7. The abbreviations used to classify air masses
use the following letters: c, m, T, P, and A.
For each letter, describe its property:
Word
Means c m T P A
continental
dry
maritime
moist
Tropical
warm
Polar
cold
Arctic
very cold

8. What would their characteristics be?mT cP
warm and moist
cold and dry

9. Complete the isotherm map in your study guide
What type of air mass
would form over each
area? Please label. cA mP mP cP mT cT mT mT

12. The Rule:
triangles and bumps
always point in the
direction the front
is moving

13. a cold front moving south
an occluded front
a stationary front with warm air on the south side
a warm front moving north
a stationary front with cold air on the south side

19. Footage Click on for video clips!
Hurricanes are intense LOW pressure that spiral counter-clockwise
Hurricanes are also known as cyclones and typhoons. They form over warm waters.

20. Tornado Footage
Tornadoes are also known as twisters. They form over land and can spiral up to 300 mph. Their strength is measured by the Fujita scale of F1 to F 5.

21. Weather Summary 1. Warm, Moist Air = Low Pressure Weather Poor
Cool, Dry Air = High Pressure Weather Good
2. Warm moist air cools by expansion
Temperature Drops
Dew point is reached
Condensation nuclei form
Clouds form PRECIPITATION?
3. As the difference between dew point and air temperature decreases chance of precipitation increases.
