3. APK - Activate Prior knowledge
On Nearpod, list two resources you could use to find out about today’s weather forecast.

4. EQ: How do air masses produce weather systems?
Read the EQ silently.
Read the EQ aloud to a neighbor.
Read the EQ to the ceiling.
Read the EQ to the floor.
What will you know at the end of class?

5. Lesson importance…WHY?
Why do you need to know how air masses produce weather systems?
Think…
Share with you neighbors.
Type your answer on Nearpod.

6. Air masses HUGE bodies of air
Can form over water (wet) or land(dry) and in tropical or polar regions.
The air mass takes on the characteristics of the area under it.

7. What is an air mass? A.) rain, sleet, snow, freezing rain, hail
B.) tornado, thunderstorm, hurricane
C.) cumulus, stratus, cirrus
D.) HUGE bodies of air

10. 4 Types of air masses
1.) Maritime Tropical (maritime=over water & tropical=warm)
Occurs with warm H20 over Gulf of Mexico area
Brings hot, humid weather & thunderstorms in summer
Brings heavy snow or rain in the winter

11. STOP and tapple Time
What does Maritime Tropical mean?

12. 2. Maritime Polar Air Mass
Maritime Polar (maritime=water & polar = cold)
Occurs with cold H20 in West Coast of US
Brings cool temperatures with fog & rain

13. STOP
Which of the following is the BEST explanation of Maritime Polar Air Mass?
A.) Maritime Polar (maritime = water & polar = cold)
B.) Maritime Polar (maritime = water & polar = cold with cold H2O In the West Coast of US)
C.) Maritime Polar (maritime=water & polar = cold) occurs with cold H20 in West Coast of US & Brings cool temperatures with fog & rain)

14. 3) Continental Tropical Air Mass
Continental= over land, Tropical=warm
Only occurs in summer in SW USA & Northern Mexico
Brings Hot, dry weather

15. STOP!
On Nearpod fill in..
When a Continental Tropical Air Mass can occur
Where is occurs
What weather it brings

16. STOP!
On Nearpod fill in..
When a Continental Tropical Air Mass can occur
Where is occurs
What weather it brings …
Continental= over land, Tropical=warm
Only occurs in summer in SW USA & Northern Mexico
Brings Hot, dry weather

17. 4) Continental Polar Air Mass
Continental=over land, polar= cold
Occurs in Central & North Canada & Alaska
Clear, cold, dry air comes to North America

18. Humidity notes Humidity: amount of H20 vapor in the air.
Temperature is important to humidity b/c the warmer the air, the more H20 vapor it can hold.
Air is saturated when no more water vapor can enter the air.

19. stop
What is humidity?
**Pulling sticks

20. stop What is humidity? **Pulling sticks
Humidity: amount of H20 vapor in the air.

21. Relative Humidity
The amount of H20 vapor in the air COMPARED to the amount of H20 vapor needed to saturate the air at a given time.
Measured with a sling psychrometer or Hygrometer……Recorded as a %
