GEOG 2050 Chapter : Atmosphere And Surface CH4
Document Summary
Energy essentials: shortwave energy from sun, longwave energy from earth. Insolation input: all radiation received at earth"s surface. Scattering: changing direction of light"s movement, without altering wavelengths: shortest wavelengths scatter the most, rayleigh scattering: relates wavelength to the size of the molecules or particles that, direct. Indirect cause scattering: shorter wavelengths f visible light (blue and violets) scatter the most, when the sun is at low-altitude, rays travel further through atmosphere, leaving only orange and reds. Absorption: anything that absorbs something and changes its state: reflect it you get cooler, absorb is you get warmer, 31% reflected radiation. Heat transfer: conduction: molecule to molecule transfer, convection: energy transferred by vertical movement, advection: horizontally dominant movement (wind, radiation: energy traveling through air or space. Latent heat: energy in phase changes of water. Heat: heat that we can feel: back and forth transfer between air and surface.
