Scattering Process by which small particles in the atmosphere deflect radiation from its path into different directions with some radiation escaping to space. Atmospheric Effects on Solar Radiation Worldwide average: 47% incoming solar radiation reaches the surface – returned to the atmosphere by radiation, conduction, convection, advection. 19% is retained in the atmosphere 34% is returned to space. Earth budget in equilibrium Characteristics of the atmosphere: c Water and Heat Energy c Water exists in 3 physical states: c solid, liquid, vapor – consider where heat energy comes from and where it goes. c Water exists in all 3 states of matter and can change phase.

Unformatted text preview: c Water changes state through: c Condensation c Freezing c Melting c Evaporation c Latent heat (hidden heat) c Water changes state c Condensation- water vapor changes to liquid water, molecules slow down and some energy is released to the environment. c Freezing – molecules move even more slowly, additional energy released to the environment c Melting – requires calories from surrounding environment, heat comes from surrounding environment. c Evaporation – requires more (uses ) calories from surrounding environment. c Sublimation – ice turns to vapor (ice cubes that shrink in your freezer without going through a liquid phase)...
