Document Summary
4 - atmosphere and surface energy balances: key concepts, mirage, reflection, albedo, absorption pg. Refraction: occurs when insolation (light) passes from one medium to another, air to water, density changes. 3: temperature differences, pink floyd symbol: visible light through prism, changes speed and direction, rainbows, atmosphere acts as a glass prism to break up white light rainbow, changes speed and direction. Latent heat: specific heat, albedo or brightness, earth"s albedo is 31% Aerosols effect: volcanic eruptions reduces temp, pinatubo (volcano erupted) reduced global tem 0. 5oc, pollutants, increased reflectivity, global dimming, remove all pollution from atmosphere temp would be warmer, pollutants decrease global warming. Insolation at earth"s surface: desert regions higher insolation, direct energy to earth"s surface more insolation. Conduction: molecule to molecule transfer, thermal energy from high temp to low temp (temp gradient, equalize temp differences, takes place in matter (solids, liquids, gases, conductivity of material, ceramics low conductivity.
