Not exact matches

These include atomic constituents such as electrons, protons, and neutrons (protons and neutrons are actually composite particles, made up of quarks), particles produced by radiative and scattering processes, such as photons, neutrinos, and muons, as well as a wide range of exotic particles.

Semiconductors emit light when bound pairs of electrons and holes, known as excitons, recombine in a process called radiative decay.

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.

He then uses what information is available to quantify (in Watts per square meter) what radiative terms drive that temperature change (for the LGM this is primarily increased surface albedo from more ice / snow cover, and also changes in greenhouse gases... the former is treated as a forcing, not a feedback; also, the orbital variations which technically drive the process are rather small in the global mean).

When you understand this process and note the overwhelming evidence supporting its existence then, and only then, will you have a correct understanding as to why the radiative greenhouse is nothing but fiction.

Gerald Marsh offered this opinion in «A Global Warming Primer» (page 4 - excerpt) «Radiative forcing is defined as the change in net downward radiative flux at the tropopause resulting from any process that acts as an external agent to the climate system; it is generally measured iRadiative forcing is defined as the change in net downward radiative flux at the tropopause resulting from any process that acts as an external agent to the climate system; it is generally measured iradiative flux at the tropopause resulting from any process that acts as an external agent to the climate system; it is generally measured in W / m2.

Convection tends to occur where radiative processes alone would make the temperature drop with height faster than the rate that air cools as it rises (the greenhouse effect is important for that, too).

The effect is a continuum of different absorption spectra that all have the same band - widenning per doubling and same effects at the center at various stages between no effect and saturation, though they are at different stages in that process for any given amount of CO2; the radiative forcing is a weighted average of the effects of each of those absorption spectra; once the center of the band is saturated for all of the spectra, the band widenning effect is the same for each and thus the forcing from the band widenning is the same as it is in the original simplified picture.

(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).

Yup, but by definition as we add greenhouse gasses, we depart from equilibrium, so the processes do not cancel and there is a net flow of energy from radiative to kinetic.

So far as I am aware, the process of condensation of water vapor, to form liquid water, is a purely thermal process; not a radiative process.

Introduction of nondimensional variables w ≡ Wρ / β and p = P / (q Oβ) results in the nondimensional equation which depends on two parameters only: The dimensionless net radiative influx r ≡ R · ɛαρ2 / (C pβ2) and a measure for the relative role of latent and advective heat transport Large l corresponds to a strong influence of moisture advection (scaling as Lq Oβp) on the continental heat budget compared with heat advection by large - scale and synoptic processes (scaling as C pβ2 w 2 / (αɛρ2)-RRB-.

The climate system includes a variety of physical processes, such as cloud processes, radiative processes and boundary - layer processes, which interact with each other on many temporal and spatial scales.

The same notation as in the text is used for wind W, precipitation P, net radiative influx R, vertical scale H and horizontal scale L. Arrows in the feedback loop indicate the amplification of one physical processes by another.

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.

As the researchers point out, the findings reinforce the need for climate models to include fully coupled stratospheric dynamical - radiative - chemical processes.

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.

A comparison of the radiative equilibrium temperatures with the observed temperatures has indicated the extent to which the other atmospheric processes, such as convection, large - scale circulation, and condensation processes, influence the thermal energy balance of the system.

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.

«Our climate simulations, using a simplified three - dimensional climate model to solve the fundamental equations for conservation of water, atmospheric mass, energy, momentum and the ideal gas law, but stripped to basic radiative, convective and dynamical processes, finds upturns in climate sensitivity at the same forcings as found with a more complex global climate model»

The radiative process described in the first model work as stated... with one caveat... W / m2 is not temperature, but is rather a consequence of temperature.

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.»

Our climate simulations, using a simplified three - dimensional climate model to solve the fundamental equations for conservation of water, atmospheric mass, energy, momentum and the ideal gas law, but stripped to basic radiative, convective and dynamical processes, finds upturns in climate sensitivity at the same forcings as found with a more complex global climate model [66].

2) Failing to acknowledge that natural variations in the effective radiating height of the atmosphere occur all the time as a result of the ever changing balance between different non radiative processes within the atmosphere.

Indeed, it is physically impossible from usual known radiative processes for any opaque body to have a surface albedo (reflectivity) as high as 0.30 yet have an emissivity of 1.

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.
