GEOG 1001 Lecture Notes - Lecture 6: Longwave, Cool Air, Shortwave Radiation
Document Summary
Scattering : changing direction of energy movement without altering its wavelength, 7% of earth"s reflectivity. Refraction : change in speed and direction of light. Reflection : energy bounces directly back out to space. Absorption : assimilation of energy by molecules and conversion to different wavelengths. Transmission : energy that passes through atmosphere or water without a change in wavelength. Light entering the atmosphere bends in which processes: refraction. What is the earth"s average albedo: 31%. Heterosphere : atmosphere layered by molecular weight and electric charge (about 100 ft. (thermosphere) up). Homosphere : composition of atmosphere is uniform (0-100ft. Given that the lapse rate is about 6. 4 c/km, mean sea level temperature is 20 degrees. C and everest is 8000 km above sea level, what is the rough temperature at the summit: about -31 degrees c. Convection : energy transferred by movement vertically, warmer air rises, cold air sinks. Advocation : horizontally dominant movement/ mixing, ex.
