To explain this finding, the study also showed that while the amount of energy available for
convection increases in a warmer and moister climate, the energy inhibiting convection also increases.

Warm summers could weaken ocean circulation: Long - term observations reveal the influence of
increased surface freshening on
convection in the subpolar North Atlantic.»
«This effect could add up
in future
warm periods and thus weaken the
convection — especially with regard to the rising temperatures and
increased melting,» the oceanographer concludes.

If
convection and evaporation were not present, I could see the argument being made that a slight
increase in Radiation having some
warming effect, however
convection and evaporation do exist within the Troposphere and the rate of cooling the two exhibit
increases as surface temps
increase.
Second even if we ignore
convection (and assume all
warming of the atmosphere is from below, ie no incoming solar radiation is absorbed
in the atmosphere) it is not the case that the atmosphere temperatures will «pivot» around some fixed level (
increasing below it and falling above it).
Consenquently, the associated SST pattern is slightly cooler
in the deep
convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler
in the nearest deep
convection source region of the South Atlantic near Africa and the Equator,
warm over the bulk of the North Atlantic, strongly
warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with
increased transport of cold water from the north whenever the Gulf Stream is running quickly.
One possible way to fix this model failure is to account for the
increased vertical flow of
convection and conduction caused by the radiative GHG induced global
warming, which apparently was, I assume, not adequately included
in the GCMs.
The point isn't a «perpetual
increase in atmospheric pressure» — that's a misnomer — if you consider the MASS of the atmosphere that is continuously «pumped» from cold air to hot air to cold air again, high up
in the atmosphere — that creates «potential energy» from the kinetic energy of the
convection — adiabatic expansion of the atmosphere is the result — the adiabatic compression occurs on the return trip of the previously
warmed (from radiative energy) air as it completes the «cycle» as it comes back down!
Increased penetrating
convection to the upper troposphere and the intensified residual circulation
in the tropical pper tropospher / lower stratosphere appear to be the most robust of these results, with a magnitude that depends upon the degree of tropical
warming.
This shift is caused by global climatic
warming that leads to higher energy
in the general circulation: The Intertropical Convergence Zone (ITCZ)-- known more commonly as monsoon —
increases in strength due to
increased convection and convergence.
Do you deny that
increasing the mass, by coupling to sub-surface material by conduction, or a (transparent) atmosphere by
convection, would reduce the rate of change of temperature, both during the cooling phase, and
in the
warming phase when the illumination is switched on again?
Take a look at Trenberth and Smith The basic idea is that
increased moist
convection lifts a lot of
warm water vapor
in the tropics (T&S) up into the troposphere at levels where the MSU are sensitive to it (Eli's ansatz).
Convection - Vertical motion driven by buoyancy forces arising from static instability, usually caused by near - surface cooling or
increases in salinity
in the case of the ocean and near - surface
warming in the case of the atmosphere.
If
convection and evaporation were not present, I could see the argument being made that a slight
increase in Radiation having some
warming effect, however
convection and evaporation do exist within the Troposphere and the rate of cooling the two exhibit

It says nothing about deep - sea temperatures, although it does reference
increased warm water and
convection (i.e. tropical cyclones)
in the Indian Ocean, which might,
in turn, be involved with the 0 - 2000 meter trend
in the Indian Ocean mentioned above (originally from Bob Tisdale).
