GEOG September 23, 2013 9:01 PM ENERGY BUDGET BY LATITUDE More incoming radiation than outgoing. We're gaining more than what we're losing, we have a surplus amount of energy. This contributes to lack of climate control and higher temperatures than expected. In higher latitudes, we lose more than we gain. Deficit amount of energy, or radiation. Consequences for areas farther from the area are cooler. Earth however,must maintain it's equilibrium. It must balance. Imbalance in energy resolved by: - Atmospheric circulations (wind, creating the hetero mix of air to be evenly distributed) ch.6 - Oceanic circulations (created by wind in the atmosphere)ch.6 - Dynamic weather systems(storms, natural disasters or uncommoncatastrophes)ch.8 If Earth was completelybalanced, we would have no wind, ocean currents, or storms.Meaning we would have no weather. Weather is what the Earth does to resolve the energy imbalance. Boundary Layer Climate K - shortwave L - longwave THESE ARE KEY TO MEMORIZE K (down) - only one: the sun is the only shortwave radiation coming down to Earth. (solar radiation) K (up) - shortwaveradiation going back up (reflected solar radiation) L (down) - longwaveradiation coming to Earth from space. Atmospheric longwave (anything in the atmospherecoming back to us on Earth) L (up) - Earth's longwave (anything we send back into the atmosphere) Arrows tell us the direction of the radiation. Radiation is coming down to the surface of Earth, or coming up from the Earth into the surface of the atmosphere. Albedo: the reflectivityof an object. A (for albedo) equals K (down) divided by K (up) Kext = the amount of energy received by the top of the atmosphere Then scattering, absorption, etc, and comesto Earth (as K down, solar radiation) (then K up, any reflected solar radiation) Then L up as Earth's longwave Then L down as Earth's atmospheric longwave Q* (Net radiation = K down + L down) which is total
