Document Summary
Daily energy: processes of energy absorption create a lag in the daily energy regime, when is the coolest time of day, no more incoming and after re-radiation of saved energy from the surface. Annual temperature lags: maximum insolation on june 21st in the northern hemisphere, surplus of energy continue for a few weeks/months depending on the location. Latitudinal imblances: at the poles, net loss and gain at the equator. Surface absorption: areas near the equator, can absorb a lot of sh energy (longer days, higher night-time temperature, northern locations, little to no energy input (sw) into the soil column, therefore have cool night temperatures (lw) Increased dust and pollution in a city helps to trap heat Temperature indices: wind chill, an index of atmospheric conditions. It is defined as a combination of wind speed and air temperature and the combined effect that it has on exposed skin.
