GLOBAL ENERGY/HEAT BALANCE HEAT: a form of energy that flows from one system or object to another because the 2 are at diff temps Temperature- the average kinetic energy of individual molecules in matter * calorie: ** Heat Transfer : by 3 mechanisms Conduction: the molecule-to-molecule transfer of heat energy as it diffuses through a substance Convection: the physical mixing involves strong upward movement ** 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: EARTH'S HEAT BUDGET : * * Q* = net radiation = incoming minus outgoing Q* = Q G + Q H + Q LE ground sensible latent heat heat heat flux flux flux (conduction) (convection) (evaporation/condensation) ** Heat Budget varies temporally & spatially
