Description
GLOBAL ENERGY/HEAT BALANCE HEAT: the total kinetic energy of all the atoms and molecules of an object or substance * Calorie = heat required to raise the T° of 1 gram of water by 1° C ** Heat Transfer: by 3 mechanisms Conduction: the transfer of energy through matter by molecular activity, the direct contact and transfer from one molecule to the next * heat flows from high T° to low T° * good & poor conductors of heat; metal (and ground) is a good conductor * insulators are poor conductors of heat,EX: air Convection: transfer of heat by mass movement within a substance. Most important mechanism for heat transfer in the atmosphere. * in the atmosphere, air is heated at the surface and then rises in mass * the sensible heat flux is one component of this, (the dry component) * evaporation/condensation, or latent heat flux, is the other component of convective heat transfer, (the wet component) ** latent heat: heat energy added to a substance without changing the T° of the substance, BUT changing the state (solid, liquid, gas) of the substance Radiation: wavelike transfer of energy EARTH'S HEAT BU
