Most stuff
about radiative equilibrium and planetary temperatures can be found in introductory astronomy texts as well as climatology papers and texts.
Not exact matches
If you doubled CO2 and let the system come into
equilibrium, the imbalance you'd measure from space would be zero — but there would still be
about 4 W / m ** 2 of
radiative forcing from the change in CO2.
As for your question
about hurricanes, the argument given for the global mean hydrological cycle doesn't apply to the hurricane because the global mean argument assumes an
equilibrium between
radiative cooling and latent heat release.
Radiative equilibrium at small LW optical thickness occurs when the whole atmosphere has a temperature such that the Planck function is
about half of that of the surface (a skin temperature), whereas at larger LW optical thicknesses, the
equilibrium profile has a signficant drop in the Planck function through the atmosphere, approaching half the OLR value at TOA and approaching the surface value towards the surface — of course, convection near the surface will bring a closer match between surface and surface - air temperatures.
It might help Peter Huybers and his collegues if we understood more
about the temperature response of the albedo of the calcite belt, and other bioogically variable components of
radiative equilibrium that impact SST in both the southern ocean and the arctic seas
He found that convective
equilibrium holds in the lower part of the troposphere up to
about 10 Km, while
radiative holds
equilibrium above.
I should have probably written that explicitely in the post in order to avoid off topic discussions
about radiative transfer or
radiative equilibrium.
He cites Möller and Manabe (1961) for the statement that pure
radiative equilibrium yields a temperature of
about 350K.
Similarly, the climate scenarios were based on 2xCO2
equilibrium GCM projections from three models, where the
radiative forcing of climate was interpreted as the combined concentrations of CO2 (555 ppm) and other greenhouse gases (contributing
about 15 % of the change in forcing) equivalent to a doubling of CO2, assumed to occur in
about 2060.
It is not the infrared emission that cools the surface as in the so - called
radiative equilibrium models because the net
radiative heat transfer surface to air is
about nil, but the evaporation whose thermostatic effect can not be overstated: increasing the surface temperature by +1 °C increases the evaporation by 6 %; where evaporation is 100 W / m ², this removes an additional 6 W / m ² from the surface.
A 1 percentage point decrease in albedo (30 % to 29 %) would increase the black - body
radiative equilibrium temperature
about 1 °C,
about equal to a doubling of atmospheric CO2.
Radiative equilibrium takes place on very fast (microsecond or less) timescales, so what on earth are you talking
about?
An albedo decrease of only 1 %, bringing the Earth's albedo from 30 % to 29 %, would cause an increase in the black - body
radiative equilibrium temperature of
about 1 °C, a highly significant value, roughly equivalent to the direct
radiative effect of a doubling of the atmospheric CO2 concentration.
If an emissivity of
about 0.87 is assigned to that Earth, the
radiative -
equilibrium temperature increases to
about 288.7 K. Each of these base temperatures gives a different value for the zero - feedback sensitivity; 0.75 and 0.78, respectively.
