Sentences with phrase «of radiative exchange»

Violation of the radiative exchange equilibrium law.

The concept of radiative exchange was the discovery of Prevost [17].

Vis.: www.garfield.library.upenn.edu/classics1981/A1981LQ21800001.pdf Even more to the point, he goes on to state that [quote] «The regions of validity of the linear, square root, and nonoverlapping approximations were considered in this article...» [endquote] and notes that the summary of the [quote] «various models and approximations for band absorption» [endquote] given in that article had apparently been useful in many later studies requiring [quote] «mathematical calculation» [endquote] of the radiative exchange by infrared bands.

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

For those who want to check out the physics, read up the statistical thermodynamics which leads to Kirchhoff; s law of radiation and realise that «Prevost exchange energy» is needed to connect the IR density of states in the two objects in radiative equilibrium and maintain absorptivity = emissivity.

Convection is based on the VERY near surface temperature whereas SB is based on the temperature of the larger air mass in radiative exchange with the surface.

However, the second law is not violated by the greenhouse effect, of course, since, during the radiative exchange, in both directions the net energy flows from the warmth to the cold.»

i) The total exchange of radiation between Space and the TOA and between surface and the TOA is sufficiently large that an increase in the radiative capabilities of an atmospheric constituent that amounts to 0.04 % of the atmosphere would appear unlikely to have any significant effect.

Given the vast pool of very cold water in the deep ocean, even modest changes in the rate it exchanges heat with the surface can produce large changes in temperature without any change in the planetary radiative balance.

The example is not meant to be an example of only one half of a radiative energy exchange.

It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.

The rationales for coupling are to investigate potentially significant feedbacks (e.g., radiative properties for different airborne crystalline ice structures, changes in air and water inertia due to suspended dust and sediments, and water and other material exchanges with plants and biome evolution) and to achieve ever fuller depictions of Earth's fluid envelope.

Lateral expansion and carbon exchange of a boreal peatland in Finland resulting in 7000 years of positive radiative forcing.

It is through these neglected mechanisms that a nearly null - net radiative exchange between surface and the bulk constituents of the atmosphere, including clouds, is maintained.

Radiative exchange between two objects of same or different temperatures works the same way.

However, six out of the 19 references in the paper are to Miskolczi himself and the fundamental equations brought up for energy balance (where radiative exchange is referenced) rely on his more lengthy 2007 paper, Greenhouse effect in semi-transparent planetary atmospheres.

With respect, Dr Spencer, it is not reasonable, indeed it verges on the mischievous, to write an allegation that Miskolczi means that radiative exchange is independent of temperature.

It will be convenient here to define the term radiative exchange equilibrium between two specified regions of space (or bodies) as meaning that for the two regions (or bodies) A and B, the rate of flow of radiation emitted by A and absorbed by B is equal to the rate of flow the other way, regardless of other forms of transport that may be occurring.

Kirchhoff showed this radiative exchange must be equal under the restrictive condition of thermal equilibrium.

``... the greenhouse models are all based on simplistic pictures of radiative transfer and their obscure relation to thermodynamics, disregarding the other forms of heat transfer such as thermal conductivity, convection, latent heat exchange et cetera.

Radiative equilibrium implies that temperatures have reached equilibrium via exchange of radiation only.

Of course radiative exchange depends on temperature, and of course Miskolczi is fully aware of thaOf course radiative exchange depends on temperature, and of course Miskolczi is fully aware of thaof course Miskolczi is fully aware of thaof that.

This and my previous posting in this series address ONLY the radiative exchange of energy.

When discussing radiative thermal energy exchange between two objects, it may very well be more appropriate to talk about the heat between objects and not mention the rate thermal energy leaves each object in the direction of the other object.

But again, this thread was started with the intention of looking at basic radiative exchanges.

That the Green House Effect works by radiative exchanges in an atmospheric column of decreasing temperatures should also be common knowledge.
