Now back to the original issue, to get a surface temperature differential of 32 Deg.

Not exact matches

This pressure gradient in turn produces a temperature differential on the surface, which prompts production of a tiny electrical current.

The diagnostics, which are used to compare model - simulated and observed changes, are often simple temperature indices such as the global mean surface temperature and ocean mean warming (Knutti et al., 2002, 2003) or the differential warming between the SH and NH (together with the global mean; Andronova and Schlesinger, 2001).

If the atmosphere consisted of Oxygen / Nitrogen only, its thermal conductivity would be very low, solar heating would be much the same, and the insulation effect (and the gravitational lapse rate) would produce a substantial temperature differential from the surface to the top of the atmosphere without any radiative absorption.

I do not know how much the radiative effect will add to the surface temperature, but it is certainly not responsible for the whole 33 degrees differential attributed to the presence of the atmosphere.

Vegetation responses to climate and rising CO2 are often cited as causal factors for differential temperature increase near the surface.

The atmosphere's temperature can and will respond much faster to changes in the temperature differential with the ocean surface.

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentiTemperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentitemperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

The differential heating imposed on the troposphere + surface layer is sufficient that LW emissions from within the layer are not able to establish pure radiative equilibrium without having the temperature profile become unstable to convection.

Sufficiently vigorous convection will tend to maintain an adiabatic (dry or moist, depending) lapse rate; near the surface there can be a superadiabatic lapse rate when the differential radiant heating is strong enough, so the temperature profile diverges from the convective lapse rate; however, the surface temperature still generally tends to follow changes in the troposphere — see 63.

the differential cloud change (dcc) of each day is equal to daily average cloud change (x), minus an averaging period of three days which begins five days prior to each date,... «-RRB-, linked to a transient decrease in cosmic rays, is associated with a transient increase of surface level air temperature.

It seems obvious to me that one has also increased the temperature differential between ocean surface and the atmosphere.

The critical thing, however is that this heat engine depends on the temperature differential between the surface of the ocean and the atmosphere above to provide the vertical convective loop.

The process of such evaporation and then condensation together with those other weather processes is an express route to get heat energy from ocean to surface to atmosphere to space and the bigger the temperature differential between ocean surface, atmosphere and space the faster they must all work to move the atmosphere back towards a temperature equilibrium.

It is just a delaying effect whereby the surface temperature increases until the increase in surface / space temperature differential in turn increases the rate of radiation to space and a new but higher temperature equilibrium is reached.

e) That a warmer ocean surface increases the surface / space temperature differential yet does not give rise to a significant increase in loss of energy to space.

A rotating uneven spherical planet with only non GHGs would radiate very freely from the surface on the night side setting up large temperature differentials and strong winds.

The point may seem minor, but it transforms «adiabatic lapse» from a sort of «miracle heating» that starts from an outside boundary condition and heats to the surface via lapse into a consequence of forced convection due to the differential delivery of heat to the surface, a dynamic process and not a static one, one that goes away if you stop actively maintaining the surface and some part of the atmosphere overhead at different temperatures.

An increase in latitudinal temperature differentials as a result of surface phenomena is not enough because it is that increase in surface differentials that prevents an ocean bulk effect from the extra DLR cause.

The oceans control the background rate of energy flow from ocean to air via The Hot Water Bottle Effect and it is the energy flow from ocean to air (supplemented to a miniscule extent by the greenhouse effect) that drives the rate of evaporation by creating varying temperature differentials between sea surface and air at the surface.

As regards a warming of the ocean skin, evaporation is a continuous process caused by temperaure, density and pressure (not just temperature) differentials between water and air so that the rate of evaporation accelerates when a water surface is warmed such as from the warming effect of extra greenhouse gases (especially if the air is dry).

The air circulation systems in both hemispheres move poleward and the ITCZ moves further north of the equator as the speed of the hydrological cycle increases due to the cooler stratosphere increasing the temperature differential between stratosphere and surface.

The air circulation systems in both hemispheres move back equatorward and the ITCZ moves nearer the equator as the speed of the hydrological cycle decreases due to the warming stratosphere reducing the temperature differential between stratosphere and surface.

There are even rare cases when the clouds are actually warmer than the surface and then the clouds are radiating downward to the surface and also to space but as you should see, this condition is short lived since it has cooler on both sides unless continually replenished with warmth to maintain the temperature differential.

Pumping power is derived from the solar energy stored in the ocean surface by means of a heat engine that uses the temperature differential between the surface water and the upwelled water.

# 18 — «The GHE only works if there is a temperature differential between the surface and the atmospheric emitter.

Specifically, for a differential area of the surface of a blackbody at a single temperature, the law gives the spectral distribution and the amount of energy radiated from that differential area into a differential solid angle.

This develops a higher temperature differential across that gap, resulting in a hotter Earth's surface even though the radiating surface did not change temperature (in a suitably averaged sense).

Part of the explanation is probably due to the fact that temperatures are more stable in the Southern hemisphere (since land heats and cools faster than ocean, and there is much more ocean in the southern half of the globe), but the surface temperature records do not show such a north - south differential.
