GHY 104 1st Edition Lecture 6Ch. 4 Atmosphere and Surface Energy BalancesEnergy Essentials- Energy Pathways and Principles- Shortwave energy in from the Sun H20, clouds, atmosphere, gases, dust intercept Energy patterns differ over deserts, oceans, mountaintops, plains, ice, etc. Presence or absence of clouds – 75% difference- Longwave energy out from Earth- Incoming and outgoing MUST balance- Transmission- passage of shortwave and longwave energy through the atmosphere or water- Our energy budget comprises shortwave radiation inputs and longwave radiation output that pass through atmosphere by transmission- Isolation- all incoming solar radiation- Isolation input - All radiation received at Earth’s surface – direct radiation and indirect radiation- Indirect radiation- diffuse radiation – scattering -changing direction of light’s movement, without altering its wavelength- Refraction- Change in speed and direction of light (light is bent)- Ex: “Rainbow” – example of refracted light Blue light has shortest wavelength and is therefore most easily scattered.- Albedo & Reflection These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Reflective quality, or intrinsic brightness of a surface = albedo- Clouds, aerosols, and the atmosphere’s albedo- Aerosols- suspension of fine solid particles or liquid droplets in gas. - Albedo- (Amount Reflection/Total Incoming) x 100, nothing more than a percentage- Dark colors absorb, light colors reflect- Absorption - Assimilation of energy into object’s molecules and conversion from one form to another.- If energy is not reflected, then it must be absorbed - Insolation that is not part of the 31% reflected from Earth’s surface and atmosphere is absorbedHeat Transfer- Sensible Heat- Heat that can be sensed and measured with a thermometer- Latent Heat- When energy is absorbed, held in storage, and later released (water vapor from boiling H2O)- Conduction- Molecule to molecule transfer of energy (hot pot handle)- Convention- Energy transferred primarily by Vertical movement (sun roof in car)- Advection- Energy transferred primarily by Horizontal movement (fog)- Radiation- Energy traveling through air or space.
