The major energy input to the climate system is radiation, not either convection or conduction, and since the latter two depend on temperature differences initially induced by radiation, they wouldn't be there on their own.

Also, why not to simply say that: Unlike major gases of the atmosphere, GHG (mainly water vapor) are heated by IR radiations and cool by IR emission and / or by convection.

In this way, the response of LW fluxes (PR) and convection (CR) tend to spread the temperature response vertically from where forcings occur — not generally eliminating the effect of RF distribution over height, although in the case with convection driven by differential radiative heating within a layer, CR can to a first approximation evenly distribute a temperature response over such a layer.

The inversion also means that air from the troposphere has difficulty entering the stratosphere so heat is not easily transported between the two by convection or conduction.

The troposphere is not everywhere at all times locally vertically coupled by convection; in particular, at night and at high latitudes, especially in winter, and where there is warm air advection aloft, some layer of air can become stable to localized convection.

In other words, Lindzen's comments are only true for a system dominated by conduction, not for one in which atmospheric convection and ocean currents play such a large role.

The only way heat can escape to space is via radiation because space is a void and therefore heat can not be transmitted by convection or conduction.

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).

However, over land, where there is not very much moist convection, which is not dominated by the tropics and where one expects surface trends to be greater than for the oceans, there was no amplification at all!

Re 40 simon abingdon — there is very little mass loss to space (can be significant for evolution of conditions over geologic time or in more extreme conditions, but not for Earth like conditions over the timescales over which climatic equilibrium is determined), and latent and sensible heat are transported by conduction and convection and mass diffusion, which can't significantly extend outside the atmosphere.

Although the Oxygen, Nitrogen and Argon components are warmed by conduction and convection they do not absorb the long wave radiation emitted by the surface and by the atmosphere as a whole.

(actually not wrong — just incomplete by not addressing ALL the convection implications - according to my current theory.)

If we call the deep ocean the bottom 3 km, then, were it not for convection carrying the heat to the surface, the total geothermal heat flux of about 20TW would raise the temperature of the deep ocean by 1K every 4000 years or so.

ie When you heatup the air by the valid GHG radiative absorbtion process, does this higher temperature create a natural increase (ie CHANGE) in convection or Not?

I do not understand how you can deny (impicitly) that an increase in ground / air temp by the GHG radiative effects (ie add 3 + degrees to the ground temp) will cause the convection / air velocity to increase.

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.

... that is almost OK... but I know if I am standing at the top of a mountain then the wind is usually very strong... thus the wind chill factor kicks in (which I assume is adding heat loss by convection) and I feel colder and may not notice the sun coming out from behind a cloud... and if I am sweating after a long climb up the mountain then I will feel very cold very quickly — regardless of the sun.

The only process that one could argue is minimally effected by CO2 is — the RATE of heat transfer from the Earth's surface — but with convective / conductive energy / mass transfer as the controlling mechanism — it would be immediately acted on by increased convection anyway — because Earth isn't surrounded by a glass bowl now is it — NO — just the cold depths of space!

The tropospheric temperature is tied to the surface temperature by convection which governs the lapse rate, so it is not possible to change one without the other.

Energy can not travel by conduction or convection through a vacuum.

Any extra warmth generated in the atmosphere by CO2 or any other trace gas will quickly be neutralised by the hugely greater effect of the oceans in so far as it has not already been dispersed by increased radiation to space, evaporation, convection, condensation and rainfall.

The atmosphere is warmed primarily by conduction and convection at the Earth's surface, not by radiation — standard school physics.

Your hypothesis assumes that increased absorption of energy in the troposphere will be transmitted to the surface by convection, since radiative transfer doesn't change if the temperature remains constant, and the radiative imbalance at the TOA wouldn't change.

This is one of the more challenging aspects of modeling of the climate system because precipitation involves not only large - scale processes that are well - resolved by models but also small - scale process, such as convection, that must be parameterized in the current generation of global and regional climate models.

The lower troposphere is heated primarily by moist convection, not radiation.

This is not simply a question of «turbulent diffusion» by the atmosphere but also of wave - like «teleconnections» propagating away from regions of tropical convection that are altered by the pattern of tropical warming.

Convection is not necessary for the autonomous thermal gradient which is the equilibrium state in a gravitational field as required by the Second Law of Thermodynamics.

There are other processes like evaporative cooling and diffusion followed by convection which can not be affected by backradiation, and which will tend to compensate for any slowing of the radiation.

Why isn't surplus energy just radiated away as easily as it was absorbed, and in addition, some could move away from the surface by convection.

14), addresses the mechanisms of atmospheric heat transfer not only via radiation but also by convection, which is not mentioned once in the IPCC's scientific reports (Ref.

As to the absorption of long - wave radiation from the earth's surface, while it may be true that carbon dioxide and water together do absorb certain frequency ranges of that radiation, I don't think that that matters a whole lot because most of the heat from the surface is transported to the top of the troposphere by conduction, convection and latent heat of vaporization of water during the day.

The air next to the ground at night will cool by conduction but a reverse convection will not take place (the ground cools by radiation loss).

As the heat transfer in the troposphere occurs mostly by convection, accumulation of CO2 in the troposphere intensifies the convective processes of heat and mass transfer, because of the intense absorption of infrared radiation, and leads to subsequent cooling and not warming as believed.

If almost all of the heat transfer from surface to upper atmosphere is by convection, then you can change anything you want about the radiation system, more GHG, less, it won't matter.

An atmosphere that is perfectly transparent to incoming and outgoing radiation can not radiate and all its heat content comes from conduction from the surface and is transported through the atmosphere solely by convection with no loss of energy to space except for the tiny fraction of atoms at the top of the atmosphere that exceed escape velocity.

36, to use your words, convection - limited would mean «It would be constrained by convective activity to keep in step with ground - level temperature, not by radiation.»
