TRANSCRIPT

  • 1. Physical Geography
    Class 12
    Temperature, EMR, Insolation

2. Matter = Stuff
All matter is made of atoms
Atoms combine to form molecules
Energy acts upon, and changes matter
Matter and Energy
3. Energy is neither created nor destroyed
It just changes form
Kinetic Energy is a form of energy.
Kinetic Energy = movement energy = temperature
Kinetic Energy
4. Temperature Scales
5. Electromagnetic Spectrum
6. Electromagnetic Spectrum
7. Longer -------------Shorter
8. Infrared Radiation
9. 10. Ultraviolet
11. Incoming Solar Radiation
Constant at top of atmosphere (when averaged annually)
~1400 watts/m2
Insolation
12. Solar Constant
13. Fate of Insolation
14. 15. 16. 17. Refraction
18. Do all wavelengths of light refract at the same angle?
19. 20. What is causing the wavelengths to bend differently?
21. Whats happening here?
22. 23. Albedo
24. What happens to absorbed radiation?
25. 26. Radiation
27. Heat Transfer
28. What methods of heat transfer are occurring here?
29. Greenhouse Effect
30. Greenhouse Effect
31. 32. 33. 34. 35. 36. 37. Latent Heat
Sensible Heat
Two Types of Heat
38. Phase Changes in Water
39. CONTROLS ON TEMPERATURE
40. Latitude
41. Mt. Kilimanjaro
42. Urbanization
43. Cloud Cover
44. Effect of Clouds on Temperature
45. Death Valley
46. 47. Look at differences in temperature
48. Effects of Land vs. Water
On Temperature
49. Continentality vs. Marine Effect
Water has a moderating effect on temperature!
50. Inland vs. Coastal
51. Evaporation
52. 53. Land heats quicker and cools quicker than Water!!!!
54. Transparency
55. Specific Heat
56. Movement and Mixing
57. Currents/ Sea Surface Temperatures
58. Warm Ocean Current
59. France vs. Newfoundland, Canada
60. Portland, Oregon
Leeward vs. Windwardside of continent
61. Landscapes
62. Glacier National ParkEast vs. West Side
63. USGS
Particulates and Gases
64. Particulates
65. Carbon Dioxide
Methane
Water Vapor
Greenhouse Gases
66. Phase Changes in Water
67. Layers of the Atmosphere
68. 69. Normal Lapse Rate
70. 71. 72. Photosynthesis
73. Depends upon
% of cloud cover
Cloud type
Cloud height
Thickness (water content + density)
Impact of Clouds
74. Examine:
Incoming shortwave radiation
Vs.
Outgoing longwave radiation
To understand actual effects:
75. Cloud Height
76. What about Jet Contrails?
