Main Body

Processes of earth atmosphere system → heat balance

Mechanisms

① Albedo from Reflected surfaces → a) clouds (whiter) b) Ice caps & Glaciers

② Evaporation from Insolation (oceans/water bodies) 71%

③ Convection via heating mechanisms and Areal distribution.

④ Turbulence due to dynamic Terrestrial heating.

⑤ Absorption by higher clouds (Cirrus) (Infrared) then Re-emission.

⑥ Reflection & Refraction from Stratosphere.
