What atmosphere level is cooler in the lower levels and warmer in the higher levels? Jet planes fly here. A. Exosphere B. Troposphere C. Stratosphere D. Thermosphere

2. Global and Local Winds https://www.youtube.com/watch?v=uBqohRu2RRk
SPI Interpret meteorological data to make predictions about the weather.

3. Air Movement  
SPI Interpret meteorological data to make predictions about the weather.
Wind is the movement of air caused by differences in air pressure
Wind ALWAYS moves from areas of high air pressure to areas of low air pressure.
The greater the difference, the faster the wind moves

4. Differences in air pressure are caused by the uneven heating of Earth
SPI Interpret meteorological data to make predictions about the weather.
Differences in air pressure are caused by the uneven heating of Earth
Uneven heating produces pressure belts which occur every 30° latitude

6. As warm air rises at the equator and moves toward the poles, it cools
Pressure Belts 
SPI Interpret meteorological data to make predictions about the weather.
As warm air rises at the equator and moves toward the poles, it cools
As it cools, some of the air sinks around 30° north and south of the equator

7. At the poles, cold air sinks and moves towards the equator
Pressure Belts 
SPI Interpret meteorological data to make predictions about the weather.
At the poles, cold air sinks and moves towards the equator
Around 60° north and south, the air begins to heat up and rise

8. These are polar easterlies, westerlies, and trade winds
Global Winds 
SPI Interpret meteorological data to make predictions about the weather.
The combination of pressure belts and the rotation of the Earth cause global winds
These are polar easterlies, westerlies, and trade winds

10. Wind belts that extend from the poles to 60° latitude
Polar Easterlies 
SPI Interpret meteorological data to make predictions about the weather.
Wind belts that extend from the poles to 60° latitude
Formed from cold sinking air moving from the poles creating cold temperatures

12. Exit Ticket  SPI 0607.8.4 Interpret meteorological data to make predictions about the weather
Answer these 3 questions on the exit ticket sticky: 1. What causes the global winds? 2. What is a pressure belt? 3. What are the polar easterlies?

13. Wind belts found between 30° and 60° latitude
Westerlies SPI Interpret meteorological data to make predictions about the weather.
Wind belts found between 30° and 60° latitude
Flow towards the poles from west to east carrying moist air over the Unites States

15. Winds that blow from 30° almost to the equator
Trade Winds SPI Interpret meteorological data to make predictions about the weather.
Winds that blow from 30° almost to the equator
Called the trade winds because of their use by early sailors

17. Doldrums SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.
Located along the equator where no winds blow because the warm rising air creates an area of low pressure

18. Most deserts on the Earth are located here because of the dry air
Horse Latitudes SPI Interpret meteorological data to make predictions about the weather.
Occur at about 30° north and south of the equator where the winds are very weak
Most deserts on the Earth are located here because of the dry air

19. Separates warm air from cold air
Jet Stream SPI Interpret meteorological data to make predictions about the weather.
The jet streams are narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere
Separates warm air from cold air

21. Generally move short distances and can blow in any direction
Local Winds SPI Interpret meteorological data to make predictions about the weather.
Generally move short distances and can blow in any direction
Caused by geographic features that produce temperature differences

22. Air moves from the ocean to the land creating a sea breeze
Sea Breezes SPI Interpret meteorological data to make predictions about the weather.
High pressure is created over the ocean during the day and low pressure over land due to uneven heating
Air moves from the ocean to the land creating a sea breeze

24. Land Breezes SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.
Low pressure occurs over the ocean during the night and high pressure over land due to the uneven heating of earth
This causes wind to move from the land to the ocean creating a land breeze

26. Question 1SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.
What causes winds?

27. Answer SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.
Winds are caused by the uneven heating of Earth’s surface, which causes pressure differences

28. What are the three types of global winds?
Question 2 SPI Interpret meteorological data to make predictions about the weather.
What are the three types of global winds?

29. Polar Easterlies Westerlies Trade Winds
Answer SPI Interpret meteorological data to make predictions about the weather.
Polar Easterlies
Westerlies
Trade Winds

30. What is the difference between a land breeze and a sea breeze?
Question 3  SPI Interpret meteorological data to make predictions about the weather.
What is the difference between a land breeze and a sea breeze?

31. Answer SPI 0607.8.4 Interpret meteorological data to make predictions about the weather.
Sea breezes occur during the day when the land is warmer than water and a land breeze occurs at night when the water is warmer than land
