4 The seasonal cycle of the heating of the atmosphere is divided into a component due to direct 5 solar absorption in the atmosphere, and a component due to the flux of energy from the 6 surface to the atmosphere via latent, sensible, and radiative heat fluxes. Both observations 7 and coupled climate models are analyzed. The vast majority of the seasonal heating of the 8 Northern extratropics (...
