GEOG 101 Lecture Notes - Lecture 5: Stevenson Screen, Advection, Solar Irradiance
Document Summary
More incoming than outgoing may over warm surface. Positive latent heat flux = energy being drawn from the surface. Negative latent heat flux = energy being added to the surface. Rn + f = -h + g + le + Or rn = -h + g + le f + . F is advection (horizontal flow of heat energy) Rn = h + g + le + f+ p. Rn = h g le f p. Each of the terms can be positive or negative depending on whether they are energy sinks or sources. Principle temperature controls within a stevenson screen. Official temperatures at weather stations come from instruments held. High latitudes have lower annual average temperatures. High latitudes have greater annual range of temperatures. High altitude has lower annual average temperature. High altitude has greater daily range of temperature. Effect of above: marine vs. continental climate. Used to heat the air + soil.
