Calculation of solar irradiance i.e. shortwave radiation flux and the atmosphere's heat radiation i.e. longwave radiation flux is important.
Not exact matches
ocean system is associated with an amplified increase in arctic surface air temperature, downward longwave radiation, and net heat flux.
The warming of the world ocean is associated with an increase in global surface air temperature, downward longwave radiation, and therefore net heat flux.
The general argument however is being discussed by rasmus in the context of planetary energy balance: the impact of additional CO2 is to reduce the outgoing longwave radiation term and force the system to accumulate excess energy; the imbalance is currently on the order of 1.45 * (10 ^ 22) Joules / year over the globe, and the temperature must rise allowing the outgoing radiation term to increase until it once again matches the absorbed incoming stellar flux.
ocean system is associated with an amplified increase in arctic surface air temperature, downward longwave radiation, and net heat flux.
The Stephens et al paper is a very incremental change from previous estimates of the global energy balances — chiefly an improvement in latent heat fluxes because of undercounts in the satellite precipitation products and an increase in downward longwave radiation.
where is the vertically integrated energy flux in the atmosphere, is the net radiative energy input to an atmospheric column (the difference between absorbed shortwave radiation and emitted longwave radiation), and is the oceanic energy uptake at the surface.
The other fluxes (shortwave and longwave radiation at both surface and top of atmosphere) show more «normal» cycles (though somewhat higher values).
where SW denotes net downward shortwave radiation, LW net upward longwave radiation, LH latent heat flux, and SH sensible heat flux I can find these products at http://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis.surfaceflux.html Regarding the latent and sensible fluxes I don't have a problem (since there are only two in the NCEP list), but regarding the others I have several.
Trenberth's energy budget schematic appears to claim a quite assymmetrical atmospheric radiation distribution; since he gives an outgoing longwave flux of 235 W / m ^ 2 of which 40 W / m ^ 2 is actually a direct path from the surface; not an atmospheric radiation.
On the 2000 meter depth graph over 2006 - 2014 of Poitou & Bréon, the yearly minima increased from 10 units to 16 units of 1022 J that is 0.41 W / m ²; but there is every year some oceanic heat storage during six months and a release of this heat the following six months: the maximum of the global outgoing longwave radiation is in July, shifted by 6 months w.r.t. the solar flux hat is maximum in January (1412 W / m ²) and minimum in July (1321 W / m ²).
As per my posts above, it is possible for DLR to increase more than evaporation, and so the warming from the DLR beats the cooling from evaporation, leading to a warming whereby the system is moving towards equilibrium by increasing temperature and hence increasing sensible heat flux and emitted longwave radiation.
[1] Total absorbed radiation (TAR), the sum of SNR [shortwave net radiation] and LDR [longwave downward radiation], represents the total radiative energy available to maintain the Earth's surface temperature and to sustain the turbulent (sensible and latent) heat fluxes in the atmosphere.
Notice that the upward longwave flux at TOA is 240 W / m ² — this balances the absorbed solar radiation.
This «flux» has come to be termed DLR (for «downwelling longwave radiation»), or sometimes DLW — the «L - W» meaning «Long - Wave.»
If surface temperature is what we care about, and the surface forcing in the tropics is very small, and the tropical ocean surface temperature being more dominated by evaporation than longwave flux, well isn't this more relevant to the problem at hand than the tropospheric radiation balance?
We use the 9 climate variables of surface air temperature (SAT), sea level pressure (SLP), precipitation (rain), the top of atmosphere (TOA) shortwave (SW) and longwave (LW) full - sky radiation, clear - sky radiation (CLR, radiative flux where clouds do not exists), and cloud radiative forcing (CRF, radiative effect by clouds diagnosed from the difference between full - sky and clear - sky radiation, Cess et al. 1990).
