1. Ocean’s affect on Weather
Sea Breezes & Hurricanes

2. Sea Breezes

3. Cause: The Sun’s energy heats the Earth unevenly.
Land heats up faster than the water in the ocean.

4. Cause:
The warmth of the land heats the air above it causing the warmed air to rise.
Cooler air above the ocean moves in over the land to take the place of the warmed air that rose upward.

6. Cause: As the warm air rises it begins to cool.
The water vapor in the warm air condenses to form clouds.
The cooled air sinks back towards the Earth.

7. Sea Breeze

8. Effect:
A convection current is created in the atmosphere over the ocean and land.
This creates a sea breeze or wind blowing in towards the land from the ocean.
Water vapor in the air condenses forming clouds.

9. Hurricanes

10. Cause: #1 - Ocean provides warm, moist air that rises.
#2 - Winds coming toward each other spiral & force the air upward.

11. Cause:
#3 - Winds at the top flow outward above the storm allowing air from below to rise
#4 - Humid air rises & makes the storm clouds
#5 - Light winds outside the hurricane steer it and let it grow

12. Convection Current

13. Effect: Convection currents within the storm
Hurricanes start off of the west coast of Africa
They move counter clockwise towards the Gulf of Mexico or the east coast of America

14. North
America
Africa
