Sentences with phrase «radiative heating within»

The climate response depends not only upon the TOA forcing, but its difference with respect to the surface value, which represents radiative heating within the atmosphere.

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.

Not exact matches

To do so, they used an existing model that describes radiative heat transfer as electrical currents flowing within two objects.

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.

The lapse rate within the troposphere is largely determined by convection, which redistributes any changes in radiative heating or cooling within the troposphere + surface so that all levels tend to shift temperature similarly (with some regional / latitudinal, diurnal, and seasonal exceptions, and some exceptions for various transient weather events).

(Within a typical atmosphere, as on Earth, heat transport by conduction and molecular mass diffusion are relatively insignificant for bulk transport (there is some role in smaller - scale processes involving particles in the air), except when the net radiative flux and convective flux are very very small (not a condition generally found on Earth).

Water vapour is lighter than air once formed by the acquisition of the latent heat of evaporation so no additional radiative energy needs to be acquired to enable it to rise within the Earth's gravitational field.

This renders «conduction, convection, latent heat» etc. as secondary considerations whose behavior is confined within a bubble of possibilities determined by the radiative budget.

How much of the energy within the atmosphere is other then radiative, conducted from the surface to convection currents, and or latent heat moved via evaporation?

If one inserts a thin and stationary horizontal adiabatic wall (well... ok, «insulated wall») at any height L within a gas column at equilibrium (no net diffusive, radiative or convective heat flows within this column) then the pressure on both sides of the wall integrated over its surface match the weight of the column above.

Would it be wrong to think that the radiative mode of heat transfer is also going on within a solid or liquid or gas?

Two physical processes are involved with heat sinks and sources within the thermometer viewshed; mass transfer and radiative transfer.

Vincentrj # 28 you are unclear re the division of your opinions / inferences between the 3 basic sub-topics (1) heat is entering the oceans due to radiative imbalance due to humans burning carbon fuels (2) the heat rate coupled with its estimated duration (based on its cause) will make it within a few decades become unprecedented during the last several thousand years and same for the surface temperature rise that will be required to stop it (3) the effects on flora & fauna will be highly negative even within this century and more so for centuries and millenia thereafter, in particular the human species which has softened much and expects much more since the days when a mammoth tusk through the groin was met with «well Og's had it, press on».

@Pierre - Normand It's special because there is no convective or latent heat transport at all within it and so radiative fluxes through the tropopause must exactly match the TOA flux after the troposphere has adjusted to the instantaneous forcing.

It's special because there is no convective or latent heat transport at all within it and so radiative fluxes through the tropopause must exactly match the TOA flux after the troposphere has adjusted to the instantaneous forcing.

There would be some small changes in the radiative heat transfer within the atmosphere, but this would also have a very small effect, because the convection compensates the changes automatically in troposphere.

-LCB- 9.4, Box 9.2 -RCB- • The observed reduction in surface warming trend over the period 1998 to 2012 as compared to the period 1951 to 2012, is due in roughly equal measure to a reduced trend in radiative forcing and a cooling contribution from natural internal variability, which includes a possible redistribution of heat within the ocean (medium confidence).
