Consider a box willed with gas, under two conditions: (1) the first box is in equilibrium, at high temperature, and thus has a high energy content; (2) the second box has low energy content, but is out of equilibrium: it is stirred by turbulent convection, produced by heating from below and cooling from above.

At the heart of the story was a statement at the recent EGU meeting by Peter Wadhams from Cambridge University, that convection in a normally active area of the Greenland Sea was much reduced last winter.

UV absorbtion by O3 is irrelevant for this point (as is convection in the troposphere) although it is key in setting the actual temperature profile.

There may be a cap for convection, but latent heating in a growing cumulus cloud (forced locally by... whatever) may eventually allow it to mushroom.

Earlier I pointed out that it could / should be better to specifically block solar IR, or in particular those wavelengths absorbed by H2O vapor, other gases and clouds, in the troposphere, rather than block all solar wavelengths indiscriminately (because selective shading could reduce the effect on convection and precipitation — caveats about cloud and H2O distribution... etc.).

Observations of the humidity in the upper troposphere and its relation with sea surface temperature in areas of deep convection point to an overall positive climate feedback by water vapour in the upper troposphere, which is inconsistent with the Iris effect.

Primarily, they affect what's going on higher up in the atmosphere, which warms the whole troposphere (which is yoked together by convection so it tends to warm and cool as a unit).

The surface and troposphere are linked by convection so that they tend to warm up and cool down together in response to changes in either the greenhouse effect or in solar heating.

In full equilibrium, at any given level, there may be some net radiative heating at some frequencies compensated by some net radiative cooling at other frequencies, with convection balancing the full spectrum radiative cooling of the troposphere and heating of the surface.

Whether the activity of cumulus convection is determined by the variables averaged over the grid box of numerical models (100 km scale for typical GCMs, 20 km scale in the case of «high resolution» GCM of MRI).

(In the full 4 - dimensional climate, responses can also tend spread horizontally by convection (advection) and temporally by heat capacity, though «fingerprints» of horizontal and temporal variations in RF (externally imposed and feedback — snow and ice albedo, for example) can remain — this spreading is somewhat different as it relies in part on the circulation already present as well as circulation changeIn the full 4 - dimensional climate, responses can also tend spread horizontally by convection (advection) and temporally by heat capacity, though «fingerprints» of horizontal and temporal variations in RF (externally imposed and feedback — snow and ice albedo, for example) can remain — this spreading is somewhat different as it relies in part on the circulation already present as well as circulation changein RF (externally imposed and feedback — snow and ice albedo, for example) can remain — this spreading is somewhat different as it relies in part on the circulation already present as well as circulation changein part on the circulation already present as well as circulation changes)

Actually there can be convection from the surface that is balanced by some of the radiation from within the troposphere, but in the approximation of zero non-radiative transfer above the tropopause, all the flux into the stratosphere must be from below (absent solar heating).

In general, so long as there is some solar heating beneath some level, there must be a net LW + convective heat flux upward at that level to balance it in equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW flux requires either that the temperature declines with height on the scale of photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by increasing optical thickness above that leveIn general, so long as there is some solar heating beneath some level, there must be a net LW + convective heat flux upward at that level to balance it in equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW flux requires either that the temperature declines with height on the scale of photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by increasing optical thickness above that levein equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW flux requires either that the temperature declines with height on the scale of photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by increasing optical thickness above that level.

Slowing such overturning by reducing the horizontal differential heating could tend to allow heat to build up at lower levels until the lapse rate is more favorable to localized vertical overturning (LVO)(The two forms of overturning are not always completely distinct or separate; for example, the Hadley cell, Walker, and monsoon circulations, as well as extratropical storm track activity (developing from baroclinic instability (Rossby wave phenomena)-RRB- are driven and organized in part by horizontal differential heating, but in the ascending portions of these circulations, cumulus - type convection can occur).
