GEOG 101 Lecture Notes - Lecture 6: Heat Flux, Sensible Heat, Energy Flux
Document Summary
To consider these other forms of energy, we use the energy balance (also called the heat budget): Rn (source) = h + g + le (all 3 variables = sink) The heat sources at night are not solar radiation. Sensible heat becomes the source of heat. H + g + le = rn. Lots of latent energy = lots of evaporation. Rn + f = - h + g + le. Rn = - h + g + le f. F is advection horizontal flow of heat energy. Rn = h + g + le + f + p. When heat is being drawn to take part in photosynthesis. Burning plants giving off heat to the surface of the earth. All terms can be positive or negative depending on whether or not they are sinks or sources. Official temperatures at weather stations come from instruments held within a stevenson screen (alternative device shown below)
