Solar energy, Uneven Heating of Earth, Wind, and Ocean Currents

  1. 1. Solar Energy Uneven Heating of Earth CAUSES… Movement of Air Masses
  2. 2. Sea Breeze Radiation = the transfer of energy though space by electromagnetic waves. Solar (Radiation) Energy
  3. 3. Sea Breeze What do you notice about the temperatures? Warm Land Cool Water
  4. 4. Sea Breeze Hot air rises Cool Water Warm Land
  5. 5. Sea Breeze Hot air rises Cool Water Warm Land
  6. 6. Sea Breeze Warm air begins to cool as it rises Cool Water Warm Land
  7. 7. Sea Breeze Warm Air flows to cooler air Cool Water Warm Land
  8. 8. Sea Breeze Cooled air Sinks b/c it is more dense Cool Water Warm Land
  9. 9. Sea Breeze Cooled air sinks Hot air rises Wind blows from Cool water to warm land Cool Water Warm Land
  10. 10. Sea Breeze Cool Water Warm Land
  11. 11. Land Breeze – At Night
  12. 12. Land Breeze Now… what's different about the temperatures?
  13. 13. Land Breeze Now… what's different about the temperatures? When the sun is down, we have cooler LAND and warmer WATER. Warm Water Cool Land
  14. 14. Land Breeze Warm Water Cool Land
  15. 15. Land Breeze Heat can be transferred in 3 ways… Conduction, Radiation, Convection The sun provides heat energy called RADIATION and it creates CONVECTION Currents in our atmosphere.
  16. 16. Label the SEA BREEZE and LAND BREEZE
  17. 17. Sun’s Rays “Uneven Heating of the Earth due to the curvature of Earth”
  18. 18. 90° 45° • Larger Angle = More intense heat (hotter) • Acute Angle = less intense heat (cooler) EARTH
  19. 19. Curved Earth = Sun rays hit Earth at angles 90° Direct Angle = Very intense heat (HOT)
  20. 20. Curved Earth = Sun rays hit Earth at angles 45° Acute Angle = less intense heat (cooler) 90° 45° Acute Angle = less intense heat (cooler)
  21. 21. Curved Earth = Sun rays hit Earth at angles Coldest at the Poles 30° 45° Equator is hottest Cooler at angles 90° 45°
  22. 22. Wind Movement of air from high pressure to low pressure
  23. 23. Wind moves from High Pressure  Low Pressure • Cold Temperature – Molecules closer together – “packed tightly” – More dense = more pressure • Warmer Temperatures – Molecules further apart – “unpacked” – Less Dense = Less Pressure Molecules want to spread out, yet… still same amount!
  24. 24. Wind blows from cold to warm
  25. 25. Earth’s Rotation • Earth rotates (spins) on its axis (very fast). • This rotation “pulls” the air as the Earth turns. • This is called the Coriolis Effect!
  26. 26. Jet Stream – upper level winds • The jet stream is located in the Stratosphere!
  27. 27. Global Wind Patterns (mid level) “Trade Winds”
  28. 28. Global Wind Patterns (mid level) “Westerlies” • From which direction are the trade winds blowing in the US? • Which direction are they heading?
  29. 29. Oceans What effect do they have on Weather?
  30. 30. Keeps the area around the water cooler (water does not change temperature)
  31. 31. Ocean Currents move warm water… North England
