Convection: o The transfer of energy by a strong vertical movement o When air heats up it becomes lighter o Light air rises o As the air rises, it cools and becomes denser o Denser air falls Convection: The transfer of heat by the mass movement of a fluid such as water and air . Advection: o The transfer of energy by horizontal movements o Winds o Ocean Currents o Both help transfer energy horizontally between the equatorial and polar regions, thus maintaining the energy balance in the E-A system. Latitudinal variation in the energy budget. Some locations have a surplus of incoming solar radiation, over outgoing energy loss, others have a deficit. The main causes of these variations are differences in latitude and

Unformatted text preview: seasonal fluctuations. Low latitudes receive more insolation than they lose by reradiation and have an energy surplus. High latitudes receive less energy than they lose, and have an energy deficit. If we did not have a heat transfer within the atmosphere or oceans, tropics would get hotter, poles colder. Heat form of energy: the total kinetic energy (KE)(motion)of all the atoms that make up a substance. Temperature o A measure of the average speed of atoms and molecules (average KE). o Higher temperatures correspond to faster average speeds. o Warm air less dense o Cold air more dense...
