GEOG 111 1st Edition Lecture 6 Outline of Last Lecture I Earth Sun Geometry a Rotation b Revolution c Tilted axis d Solar declination e Solar elevation f Solar insolation Outline of Current Lecture I Energy Transfer a Radiation transfer b Heat transfer c Energy imbalances and energy transfer Current Lecture I Energy Transfer through radiation and heat transfers Q net radiation a Radiation transfer the net amount of radiation available i Local radiation budget Q K incoming K outgoing L incoming L outgoing ii K shortwave L longwave iii If Q 0 net energy gain and temperature rises If Q 0 net energy loss and temperature falls If Q 0 radiation balance and no temperature change iv Factors that control the values of the equation 1 Incoming shortwave seasonal diurnal cycle clouds particulates 2 Outgoing shortwave albedo light colored surfaces will reflect the incoming light 3 Incoming longwave coming from the atmosphere greenhouse gases the more the higher the temperature clouds 4 Outgoing longwave reflected back to the atmosphere These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute v How does local radiation budget plot change if the following conditions are observed 1 Cloudy skies Q isn t going to be nearly as high and the temperature isn t going to be as high the day s temperature range isn t as big clouds are very effective in absorbing longwave radiation 2 Dry conditions low concentration of water vapor in the atmosphere 3 Snow cover snow is a very effective emitter slightly cooler conditions at night because waves are emitted back to the atmosphere Q 0 Q 0 Q 0
