Sentences with phrase «radiative transfer processes»

Greenhouse gases cause radiative transfer processes to change.

In brief, the temperature profile of the atmosphere is set by convection & latent - heat considerations (= > adiabatic lapse rate); based upon that temperature profile, the radiative transfer processes give rise to the radiative forcing which is the GHE.

Water itself effectively absorbs all incident infrared solar radiation (e.g., Morel and Antoine, 1994), and this direct radiative transfer process provides roughly half of the heat to the ocean surface waters.

But you will agree that this radiative transfer process will not impact the change in the number of molecules that occurred upon condensation.

Not exact matches

We will also discuss the theory of planetary physical processes (e.g. circulation, dynamics, thermodynamics, radiative transfer, cloud microphysics) and review the current status of the modelling of planetary atmospheres in order to calculate observables such as light curves.

Since many of these processes result in non-symmetric time, location and temperature dependant feedbacks (eg water vapor, clouds, CO2 washout, condensation, ice formation, radiative and convective heat transfer etc) then how can a model that uses yearly average values for the forcings accurately reflect the results?

Concluding: not only radiative process contribute to the transfer of energy from the surface to outer space.

but it also means that the GHG impact is simply a transfer of some of the transport process from radiative to convective.

The LBLRTM is based on the FASCODE line - by - line model, wherein the radiative transfer aspect of the code has been substantially rewritten to support operation on vector processing platforms.

The exact balance of the energy transferred from the surface via radiative and convective processes seems not to be accurately known (as far as I have read to date), but non-radiative processes dominate.

Waquet, 2015: OSOAA: A vector radiative transfer model of coupled atmosphere - ocean system for a rough sea surface application to the estimates of the directional variations of the water leaving reflectance to better process multi-angular satellite sensors data over the ocean.

About 40 years ago, using electrical heating of horizontal plates of hot - rolled steel and aluminium to separate natural convective and radiative heat transfer, I measured the former and deduced the latter by difference as a function of local GHG composition and temperature to design large process plant.

When oceans are carrying heat deeper below the surface, then the atmospheric heat is removed by transference processes of wind, current and radiative transfer.

The reason is that for a macroscopic object such as an ordinary mercury thermometer or a spacecraft, radiative heating and cooling processes will dominate (by orders of magnitude) over convective heat transfer with the thin thermosphere.

Energy transfer dominated by radiative processes is minimally affected by convection and conduction if the matter temperature is much smaller than the radiation temperature.

Because of the high beam temperature, radiative transfer dominates over the other, more destructive and undesirable heat transfer processes of convection and conduction, making lasers effective tools for surgery.»

Your model appears correct for a solely radiative heat transfer process occurring in a vacuum.

Furthermore, a model that could realistically simulate the impact of increasing atmospheric particle concentration on climate must eventually include the simultaneous coupled effects of all the important atmospheric processes, such as fluid motions and cloud microphysics, in addition to the radiative transfer effects.»

Unfortunately radiative heat transfer plays a relatively small role in the heat transfer processes occurring between a sphere and a relatively dense, gaseous atmosphere under the influence of a gravitational field.

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

These processes include arctic clouds and their radiative impacts, sea - ice albedo changes, surface energy fluxes, vertical momentum transfer, and ocean vertical heat transport.

I am not saying that: What I am saying is that the spontaneous process of radiative heat transfer between two objects consists of two sub-processes: radiation from the hot object passing to the cold object and radiation from the cold object passing to the hot object.

We can not measure total radiative forcing, with or without temperature feedbacks, because radiative and non-radiative atmospheric transfer processes combined with seasonal, latitudinal, and altitudinal variabilities defeat all attempts at reliable measurement.

I made the suggestion that the NET radiative flux should be compared with other heat transfer processes; you think otherwise.

But a reminder, you are doing V&V on the dynamic core, the bottom boundary conditions (like orography), each individual parameterization (e.g. radiative transfer, convection, boundary layer, clouds, etc), and in the case of coupled models the ocean module, the sea ice module, the land process module, the aerosol module (and in future the ice sheet module), in stand alone mode as well as when coupled in the climate model.

As you point out, there are many different combinations of heat transfer processes and states of the atmosphere and surface that can provide that same value of tropopause radiative fluxes.

For a comprehensive GCM I can count oceans, land, atmosphere, ice, biological processes, organic and inorganic chemical processes, human - made sources and other effects, radiative energy transport, conduction and convective heat transfer, phase change, clouds and aerosols, as some of the important system components, phenomena, and processes.
