Transmission
The passage of shortwave and longwave energy through either the atmosphere or water.
Four main outcomes to incoming energy
Scattering
Refraction
Reflection
Absorption
The molecules change the direction of the insolation without changing the wavelength
Scattering
The downward component of scattered light
Diffuse radiation
The shorter the wavelength, the greater the scattering
Rayleigh scattering general rule
Light is bent
Refraction
Energy hitting Earth and bouncing back into space, without being absorbed or performing work
Reflection
The reflective quality of a surface measured in percent
Albedo
Controls the amount of absorption for a surface
Albedo
Assimilation (take in) of radiation by molecules of matter and its conversion from on form of energy to another
Absorption
Any insolation that is not part of the 31% reflected back to space is…
Absorbed
Four modes of heat transfer on Earth
Conduction
Convection
Advection
Radiation
Molecule-to-molecule
Conduction
Physical mixing of gas or liquid in a vertical motion (ocean circulations)
Convection
Physical mixing of gas or liquid in a horizontal motion (wind)
Advection
Transfer using electromagnetic waves
Radiation
Incoming shortwave energy passes through the atmosphere
The Greenhouse Effect
Outgoing longwave energy is absorbed by the atmosphere and emitted back to Earth
The Greenhouse Effect
+SW-SW+LW-LW=
NET R
The energy stored in water vapor as water evaporates
Latent heat of evaporation
Back-and-forth transfer between air and surface through convection and conduction
Sensible heat
Things that can influence NET R
Daylength
Cloudiness
Latitude
& many other things…
