Latitude Note that in this representation Annual incoming radiation depends on the latitude whereas the annual outgoing radiation doesn’t – how to explain the apparent paradox?

NOAA Radiation Budget monthly mean (December 2010) (W/m2): Tropical regions get more shortwave radiation than extratropical regions (high latitudes) Absorbed solar radiation is the difference between the incoming solar radiation at the top of the atmosphere and the outgoing reflected flux at the top of the atmosphere

Annual mean Outgoing Longwave Radiation Measured by satellite: in fact, less OLR is emitted in high latitudes: cold emits less

Consequences… Net radiation budgets vary with latitude Variations in sun angle and day length Positive in the tropics, negative in polar regions Particularly strong gradient in winter Temperature variations with latitude
