Sentences with phrase «radiant energy transfer»

Leaving no more than 40 % as Radiant Energy transfer, with 24 % of that 40 % as direct loss to Atmospheric Window.

However, if extra CO2 reduces the cooling rate of the Earth surface, and the rate of radiant energy transfer from Sun to Earth surface is little changed, then the Earth surface will warm (other things being equal) from what it was before the increase in CO2.

Not exact matches

PS when molecular collisions are frequent relative to photon emissions and absorptions (as is generally the case in most of the mass of the atmosphere), the radiant heat absorbed by any population of molecules is transfered to the heat of the whole population within some volume, and molecules that emit photons can then gain energy from other molecules.

It is the density, not the composition which gives more or less opportunities for such instances of energy transfer between molecules whilst the incoming and outgoing radiant energy is negotiating the atmosphere.

The radiant heat we feel from a fire is the fire's thermal energy, its heat energy — we can feel heat energy transferred by radiation (as well as by conduction and convection).

This is heat energy transferred by radiation, direct to us who feel the heat on our skin and absorb it deeply and feel it internally as this aka radiant heat heats up the water in us, heats our blood and flesh and bones..

No surface can emit energy any faster than energy can be transferred to the radiant surface.

If the average radiant layer were 288K @ 390Wm - 2 and you didn't have to consider other non-radiant means of energy transfer, that would be a fair estimate.

Terrestrial radiation absorbed by CO2 is immediately thermalized, i.e. the radiant energy absorbed by CO2 molecules is immediately (about 0.1 nanosecond) transferred (in a process similar to thermal conduction) to other atmospheric molecules which outnumber CO2 molecules 2500 to 1.

Radiant energy accounts for all of the outbound energy at the top of atmosphere, but only a fraction of the energy transfer at the surface.

The main issue is an understanding of the physical processes regarding density and the energy transfer along with the conversion of radiant energy to mechanical energy and the currents of the oceans.

The fundamental equation of radiative transfer at the emitting surface of an astronomical body, relating changes in radiant - energy flux to changes in temperature, is the Stefan - Boltzmann equation --

whereF is radiant - energy flux at the emitting surface; εis emissivity, set at 1 for a blackbody that absorbs and emits all irradiance reaching its emitting surface (by Kirchhoff's law of radiative transfer, absorption and emission are equal and simultaneous), 0 for a whitebody that reflects all irradiance, and (0, 1) for a graybody that partly absorbs / emits and partly reflects; and σ ≈ 5.67 x 10 — 8 is the Stefan - Boltzmann constant.

In the atmosphere, you do not have a closed system, so such thermal equilibrium can hardly be present, given that all manner of things, are driving radiant energy into any volume of atmosphere, as well as conductive, and mass transport (convective) energy transfers are taking place.
