Sentences with phrase «solar radiative heating»

There are of course other processes that heat the atmosphere including solar radiative heating; but what we call the «greenhouse» effect; at least to the point that it heats the atmosphere, is demonstrably real, and fighting that is a poor choice of causes to die for.

«Significant increasing trends in DSR [DownwardSurface Radiation] and net DSR fluxes were found, equal to 4.1 and 3.7 Wm ⁻², respectively, over the 1984 - 2000 period (equivalent to 2.4 and 2.2 Wm ⁻² per decade), indicating an increasing surface solar radiative heating.

Not exact matches

If the atmosphere consisted of Oxygen / Nitrogen only, its thermal conductivity would be very low, solar heating would be much the same, and the insulation effect (and the gravitational lapse rate) would produce a substantial temperature differential from the surface to the top of the atmosphere without any radiative absorption.

But the troposphere can still warm with an increased radiative cooling term because it is also balanced by heating through latent heat release, subsidence, solar absorption, increased IR flux from the surface, etc..

As far as I know, if the only physical mechanism under consideration is the radiative cooling of the planet's surface (which was heated by shortwave solar radiation and reradiated at longer wavelengths in the infrared) via radiative transport, additional gas of any kind can only result in a higher equilibrium temperature.

... interestingly in the grey gas case with no solar heating of the stratosphere, increasing the optical thickness of the atmosphere would result in an initial cooling of and in the vicinity of the skin layer (reduced OLR), and an initial radiative warming of the air just above the surface (increased backradiation)-- of course, the first of those dissappears at full equilibrium.

For simplicity, assume all solar heating at the surface (so that the lapse rate is (1 - dimensional climate model, radiative convective equilibrium) positive or approaching zero but never negative) unless otherwise stated:

Re my 441 — competing bands — To clarify, the absorption of each band adds to a warming effect of the surface + troposphere; given those temperatures, there are different equilibrium profiles of the stratosphere (and different radiative heating and cooling rates in the troposphere, etc.) for different amounts of absorption at different wavelengths; the bands with absorption «pull» on the temperature profile toward their equilibria; disequilibrium at individual bands is balanced over the whole spectrum (with zero net LW cooling, or net LW cooling that balances convective and solar heating).

It's because both land and ocean surfaces are heated by shortwave solar radiation and where aerosols reflect SWR equally well over land or water and where greenhouse gases work by retarding the rate of radiative cooling which is not equal over land and water.

Translation by Richard Taylor, «Memoir on Solar Heat, the Radiative Effects of the Atmosphere, and the Temperature of Space,» Scientific Memoirs 4 (London: Taylor and Francis, 1846).

The radiative Greenhouse Effect is continually overridden as a result of the size of the constant interlinked changes in both the solar energy input to the oceans and the oceanic heat inputs to the atmosphere.

«Global Upper Ocean Heat Storage Response to Radiative Forcing from Changing Solar Irradiance and Increasing Greenhouse Gas / Aerosol Concentrations.»

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.

Climastrologists assumed the surface of our planet to be a near blackbody that could only heat to 255K for an average of 240 w / m2 of solar radiation if there were no radiative atmosphere.

However there is no law that says radiative transfers have to balance, in fact we know from the law of conservation of energy that this isn't the case: a solar panel has no radiative equilibrium because the incoming radiation is converted into heat.

Extra heat from all sources — including the interior of the planet, fossil fuel burning, nuclear fission, solar radiance, north - south asymetry and — the big one — cloud radiative forcing — is retained in planetary systems as longwave emissions and shortwave reflectance adjusts to balance the global energy budget.

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.

This is achieved through the study of three independent records, the net heat flux into the oceans over 5 decades, the sea - level change rate based on tide gauge records over the 20th century, and the sea - surface temperature variations... We find that the total radiative forcing associated with solar cycles variations is about 5 to 7 times larger than just those associated with the TSI variations, thus implying the necessary existence of an amplification mechanism, although without pointing to which one.

These measurements could allow climatologists to determine the role of the solar and radiative forcings on the increase in heat content of the late 20th century relative to that of the deep ocean circulation.

A small localized change in surface temperature can cause a convection burst (thunderstorm) and a large increase in convection height, improving both reflection of incoming solar radiation, and conveying sensible heat to a higher altitude where it can then escape to space via radiative processes with far less interference.

Although we focus on a hypothesized CR - cloud connection, we note that it is difficult to separate changes in the CR flux from accompanying variations in solar irradiance and the solar wind, for which numerous causal links to climate have also been proposed, including: the influence of UV spectral irradiance on stratospheric heating and dynamic stratosphere - troposphere links (Haigh 1996); UV irradiance and radiative damage to phytoplankton influencing the release of volatile precursor compounds which form sulphate aerosols over ocean environments (Kniveton et al. 2003); an amplification of total solar irradiance (TSI) variations by the addition of energy in cloud - free regions enhancing tropospheric circulation features (Meehl et al. 2008; Roy & Haigh 2010); numerous solar - related influences (including solar wind inputs) to the properties of the global electric circuit (GEC) and associated microphysical cloud changes (Tinsley 2008).

At the surface, the solar heating — net LW cooling = net radiative surface heating = convective cooling = sum of sensible and latent (evaporative) cooling.

Looking at the last decade, it is clear that the observed rate of change of upper ocean heat content is a little slower than previously (and below linear extrapolations of the pre-2003 model output), and it remains unclear to what extent that is related to a reduction in net radiative forcing growth (due to the solar cycle, or perhaps larger than expected aerosol forcing growth), or internal variability, model errors, or data processing — arguments have been made for all four, singly and together.

He arrives at his inflated value by conflating the radiative surface warming from GHG's and clouds with the return of latent heat, thermals and solar energy absorbed by clouds and subsequently sent to the surface which are otherwise already accounted for by the net surface temperature and its consequential BB radiation.
