1. Wind: Sea Breeze and Land Breeze

2. EnergyTransfer in the Atmosphere Energy moves through the atmosphere in three different ways-conduction, convection and radiation Convection is the main way that air circulates in the atmosphere

3. What is convection? Energy transfer due to differences in density Occurs in liquids and gases Warm air rises Cool air sinks Forms a convection cell

4. Specific Heat The amount of energy required to raise the temperature of a substance 1degree celsius measured in joules see esrt for more information

5. Which substance has a higher specific heat?

6. Which substance will have a higher specific heat? Land or Water? Why?

7. Water will have a higher specific heat because it will reflect the sun’s incoming solar radiation....

8. Therefore...water will take a longer time to heat up, but will retain this heat for longer...so...

9. A sea breeze will form... Sea Breeze: wind moves from ocean to land The atmospheric pressure is higher over the ocean then over the land because the air is cooler during the day At night the air is cooler over the land, so a land breeze forms

11. At night a land breeze develops...

12. Wrap UP:

13. 1.Why does the ocean heat up more slowly than the land? 2.Which substance has a higher specific heat-lead or ice? 3.Why do thunderstorms usually happen at the end of a hot summer day? 4.Why do people like to sit near the ocean on a hot summer day?
