Document Summary
Energy from the sun: weather: short-term state of atmosphere temperature, moisture, wind, barometric pressure, climate: average long-term weather conditions for a region of earth temperature, precipitation (dictated by latitude, tilt, energy supply is from the sun. Earth"s greenhouse: strength controls warmth of bodies of water and atmosphere. In-coming uv radiation passes through the atmosphere more readily than infrared: carbon dioxide, methane increasing most rapidly, reflect infrared radiation back towards earth. Energy from impacts: meteoroids, asteroids, comet impacts. Chapter 10: the physics and chemistry of water and air. This leads us, finally, into a consideration of winds: produced by variations in pressure in the atmosphere (high low) Isobars show gradient of pressure lines (close = faster airflow) Wind will initially tend to follow the pressure cells we noted earlier: air flow spirals outwards from a high-pressure area (ferrell cells, hadley cells, etc). Ocean near antarctica: upwelling brings water back to the surface winds, coriolis effect.
