It is also funny to think that this "advected" energy flux is of the same order of magnitude as the global average of the incoming radiation (1361W/m²/4 = 340.25 W/m²) and that this energy is extracted from entry of "cool" air in the upper part of the atmosphere and output of much warmer air in the lower part of the atmosphere. The -15 W/m² energy should be delivered by the compression of the air mass during its subsidence. could someone confirm it is realistic?
