Terms and Concepts to Know from the Lectures8 Global Energy Balance & Temperature Distribution8.1 Insolation in the AtmosphereSolar constant-how fast the energy reaches Earth’s surface from the sun. Can be 1,388 watts persquare meter.Energy balance: based on the amount of calories you intake, that’s your energy input. But theenergy out it is the number of calories you burn each day. Calories in and out equation,Insolation: aterm that refers to a population of animals. Or other genetic material with otherorganisms of the samespecie’s. It also is often the result of an accidentAbsorption:when solar radiation is caught and held by a substance it converts into heat energy.Usually inearth’satmosphere temperatures get no higher than 1800 degrees CelsiusScatteringthe process of scattering, when small particles of gas diffuse part of the incomingradiation. The move randomlybut don’t move the wavelength of the electromagnetic energy(Selective and Non-selective scattering Reflection):nonselective is scattering when the particlesdiameter in the atmosphere is bigger than the wavelength of the radiation. Nonselectivescattering is when all the radiation is even throughout the visible and infrared portion of thespectrum.Transmission: The ability of a medium to allow electromagnetic waves to pass through it.Direct & diffused radiation Albedo:direct is solar radiation received by the earths atmosphere.Only one that has not been alters by atmospheric scattering. Diffused is one that has beenmodifiedShortwave/longwave radiation Counter radiation:shortwave radiation contains a lot of energy.Longwave radiation contains less energy than a shortwave. Infrared rays form when long wavesemit energy8.2 Net RadiationEnergy balance:the process of redistributing energy int eh Earths systemNet radiation: occurring at the top of the atmosphere, this is the balance between incoming andoutgoing energyConduction: when heat moves from areas of more heat to areas of less heart and distributes tomake molecules vibrate rabidly and collide transferring energyConvection:convection produces wind and ocean current. This is the heating of earths surfaceand atmosphere.Latent heat:when water evaporate from land or water. Heat moves from the surface to theatmosphere. When condensation leavesSensible heat:moves heat from warm to cold objects by conduction when they are in directcontact. Can also carry heat energy away from a surface8.3 The Greenhouse EffectGreenhouse effect:when radiation from the sun reflection enters suns earth’s atmosphereremission is absorbed by the land and water. Some of its reflected back into the air. This causesheating of the earth9. Winds: Global & Local9.1 Global Pattern of Net RadiationGlobal variation in net radiationcalled net flux, a the tip of the atm. The balance of outgoing aswell as incoming energy.
