Sentences with phrase «with radiation flux»

It seems to me that the two papers use at least a similar approach — and one that seems very sensible to me — correlating surface temperature with radiation fluxes at the top of the atmosphere.

Refraction, specifically the real component of refraction n (describes bending of rays, wavelength changes relative to a vacuum, affects blackbody fluxes and intensities — as opposed to the imaginary component, which is related to absorption and emission) is relatively unimportant to shaping radiant fluxes through the atmosphere on Earth (except on the small scale processes where it (along with difraction, reflection) gives rise to scattering, particularly of solar radiation — in that case, the effect on the larger scale can be described by scattering properties, the emergent behavior).

Finally, going back to Bryan's remark, he is certainly correct that the physical heat flow generated at ridges etc is tiny with respect to the flux of SW radiation.

ocean system is associated with an amplified increase in arctic surface air temperature, downward longwave radiation, and net heat flux.

So actually the local radiation field is much simpler that what you're trying to describe: in the transparent windows, it's just the emitted intensity from the source (sun + ground), and in the opaque lines, it is nearly isotropic with the excitation temperature of the molecules close to the local kinetic temperature if collisions are numerous enough, with a small anisotropy linked to the net radiation flux.

If it is in an isothermal layer, it will radiate upward as much as downward; it will decrease the baseline TRPP net flux and increase the baseline TOA flux by the same amount, but it will decrease the baseline TOA flux by a greater amount if it is absorbing radiation with a higher brightness temperature from below (the baseline upward flux at TRPP), so it will increase the amount by which the baseline net flux at TRPP is greater than that at TOA.

The calculations estimate the reduction in the energy flux density with distance away from the sun (Gauss» theorem) and the black body radiation describing the rate of planetary heat loss.

Within a convecting layer, convective fluxes can also be part of the response, but where convection is bounded within a layer, the layer as a whole must respond with radiation to radiative forcings and feedbacks.)

Our observational studies (Gray and Schwartz, 2010 and 2011) of the variations of outward radiation (IR + albedo) energy flux to space (ISCCP data) vs. tropical and global precipitation increase (from NCEP reanalysis data) indicates that there is not a reduction of global net radiation (IR + Albedo) to space which is associated with increased global or tropical - regional rainfall.

Over land, you have a surface energy balance that includes downwelling IR, upwelling IR (Stefan Boltzmann), downwelling solar radiation minus what is reflected back from the surface, latent heat flux and sensible heat flux (these are turbulent fluxes associated with exchange with the atmosphere), and conductive flux from the ground (below the surface).

A SOM is much cheaper and simpler to run compared to a full ocean model, but still reacts to things happening in the atmosphere, like changes in downwelling radiation or fluxes associated with surface wind.

Sea ice with its strong seasonal and interannual variability (Fig. 1) is a very critical component of the Arctic system that responds sensitively to changes in atmospheric circulation, incoming radiation, atmospheric and oceanic heat fluxes, as well as the hydrological cycle1, 2.

Bill Gray has a favorite diagram, taken from a 1985 climate model, showing little nodules in the center with such labels as «thermal inertia» and «net energy balance» and «latent heat flux» and «subsurface heat storage» and «absorbed heat radiation» and so on, and they are emitting arrows that curve and loop in all directions, bumping into yet more jargon, like «soil moisture» and «surface roughness» and «vertical wind» and «meltwater» and «volcanoes.»

We checked this assumption by comparing TEC obtained at three selected sites in Europe (cf. http://swaciweb.dlr.de) with the solar activity dynamics represented by the radio flux index F10.7 which is also a proxy for EUV radiation changes (see Fig. 6).

In Chapter 5 there are steady state measurements of Ar / N2, CO2 / N2 and O2 / N2; along with photosynthetic radiation flux.

In all of these simple models, we assume the atmosphere to have a volume as fixed as a bathtub, we assume that the atmosphere / ocean system is a closed system, we assume that the incoming radiation from the Sun is constant, we assume no turbulence, we assume no viscosity, we assume radiative equilibrium with no feedback lag, we take no account of water vapor flux assuming it to be constant, no change in albedo from changes in land use, glacier lengthening and shortening, no volcanic eruptions, no feedbacks from vegetation.

The flux of heat from the ground, however, can not keep up with radiation cooling if the sky is clear.

Certain things come out of it easily, such as the concept of black body radiation and balance of energy flux with energy density in a cavity (for example).

In contrast to this, the calculated TOA outgoing radiation fluxes from 11 atmospheric models forced by the observed SST are less than the zero feedback response, consistent with the positive feedbacks that characterize these models.

The climate models create ~ 66 % more than real lower atmosphere warming by the fake «back radiation» idea, taught in US Atmospheric Science for ~ 50 years, coupled with the fake single -18 deg C OLR emitter idea, which provides an imaginary negative Down flux in the bowdlerised two - stream approximation (blame Sagan for this).

A significant flux of solar radiation was found to penetrate the entire thickness of the atmosphere, with the amount at the ground 1.5 % of that incident on the top of the atmosphere.

Maps of the long - term monthly and annual means of the net surface energy flux together with the four components of the total flux (latent heat flux, sensible heat flux, incoming radiation, and outgoing radiation) for the global oceans are presented.

It might help you if you had a few concepds in mind too when considering this subject, like «space» is the big energy «sink» with old sol (and the internal heat generating processes (including nuclear) of the earth) as sources... any mechanism that results in a delay of energy leaving earth, such as a «bounce - back» or a re-rad of energy (like back radiation) certainly is going to increase the «energy flux» in the system, and this in any way you want to frame the argument translates to a «higher» energy state, and a higher so - called temperature» (movement in matter, velocity of air molecules or oscillations in certain «resonant molecules) as well.

This is an appalling failure of basic teaching because it leads directly to the «back radiation» myth, confusing Emittance with a real energy flux.

In other words, a bigger share of the 240 W / m 2 of the vertical energy transport will be transported by convective / advective means with a stronger GHE, and a smaller share by radiative means because the sum of convective vertical energy transport plus the diminished radiative flux must add up to about 240 W / m 2 in order to balance the incoming shortwave radiation.

Since the intensity of infrared radiation increases with increasing temperature, one can think of the Earth's temperature as being determined by the infrared flux needed to balance the absorbed solar flux.

The 2008 K&T cartoon gives a NET upward radiation flux from the surface of 33w / m2 with a downward adjustment to water vapour to 76w / m2 and conduction to 16w / m2 but the point holds; that point is more net heat is leaving the surface through methods other than radiation, particularly water; that to me means 2 things; water is a dominant mover of heat compared to CO2 and the sun's 168/166 w / m2 is a far more dominant heater than CO2 backradiation.
