1. Begin working on the winds worksheet from the quiz day.
I will put 15 minutes on the timer and that is the time you have to finish this.
I will collect what you have completed after the 15 minutes.
Work INDEPENDENTLY and get this done. The readings will give you the answers to the worksheet.

2. TOC – Pg. 33 Air Movement

3. The greater the difference, the faster the wind moves
Air Movement
Wind is the movement of air caused by differences in air temperature and pressure.
The greater the difference, the faster the wind moves

4. Hot vs. Cold
Rises
Hot air
Cold air
Sinks

5. Coriolis Effect Circulation of the Atmosphere
Solar Radiation - initial source of energy to the Earth.
Radiation can be absorbed, reflected and reradiated.
The redistribution of this energy controls the structure and dynamics of the Atmosphere and Oceans.

6. The air in the atmosphere moves in response to uneven solar heating and Earth’s rotation. Solar energy is absorbed into Earth’s surface. This absorbed energy is converted into heat or infrared radiation.

7. The Solar Heating of Earth Varies with Latitude
At high latitudes solar radiation travels a longer path through the atmosphere and is less direct.
What factors govern the global circulation of air?
Uneven solar heating
The Coriolis effect

9. Re-distribution of heat
Heat is gained at Equatorial latitudes and heat is lost at higher latitudes
Winds and ocean currents redistribute heat around the Earth
Warm equatorial water flows to higher latitudes
Cool Polar water flow to lower latitudes

10. Earth’s Uneven Solar Heating Results in Large-Scale Thermal Cell type of Atmospheric Circulation. These large scale cells are created through the energy transfer Convection.
A convection current forms in a room when air flows from a hot radiator to a cold window and back.
Air warms, expands, becomes less dense, and rises over the radiator. Air cools, contracts, becomes more dense, and falls near the cold glass window.
A convection cell is driven by density differences

11. Differences in air pressure are caused by the uneven heating of Earth
Uneven heating produces pressure belts which occur every 30° latitude

12. Think about where heat is found on our Earth.
Where are the hottest areas???

13. Where is the hottest areas on the globe?

14. Think about where cold is found on our Earth.
Where are the coldest areas???

15. Where is the coldest areas on the globe?
