Sentences with phrase «solar radiative»
The phrase "solar radiative" refers to the energy or radiation that comes from the sun. It describes the electromagnetic waves emitted by the sun, such as light and heat, that travel through space and reach the Earth. Full definition
Other causes, including solar radiative output variations, are thought to be less important, but they are also far less certain.

The unsolved puzzle of how subtle variations driven by Earth - orbit changes can affect the climate suggests a closer look at feedback processes, including other pathways than direct solar radiative forcing.
«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.
Dutton, E. G. & Christy, J. R. Solar radiative forcing at selected locations and evidence for global lower tropospheric cooling following the eruptions of El Chichón and Pinatubo.
Such changes are apparently sufficient to trigger major changes in climate — implying that the Earth's climate system may be more sensitive to small solar radiative perturbations than one might think.
«The solar radiative forcing of climate increased by 0.1 [watt per square meter].»
The solar radiative forcing is TSI in Watts per square meter (W - m - 2) divided by 4 to account for spherical geometry, and multiplied by 0.7 to account for planetary albedo (Meehl 2002).
In fact, there is reasonably compelling evidence that changes in drought in the western U.S. over the past millennium may, in large part, reflect the forced response of ENSO to past volcanic and solar radiative forcing.
This includes the application of improved thermal and solar radiative transfer, as well as investigations concerning enhancements in the simulation of convective processes in climate models.
In order to determine the solar contribution, we have to start with the solar radiative forcing, which is the change in total solar irradiance (TSI) in Watts per square meter (W / m2) divided by 4 to account for spherical geometry, and multiplied by 0.7 to account for planetary albedo (Meehl 2002).
Using the oceans as a calorimeter to quantify the solar radiative forcing (PDF), Nir J. Shaviv, 11/2008, Journal of Geophysical Research, Volume 113, Issue A11
Solar radiative forcing is a direct energy source to the Earth and is related to the change in TSI by ΔF = ΔTSI · (1 − A) / 4, where A is the Earth's albedo.
We also show, using the SIM data, that solar radiative forcing of surface climate is out of phase with solar activity.
Numerous attempts to confirm these correlations based on different climate models have shown that it is only possible if either the applied perturbations of direct solar radiative forcing are large (consistent with a direct solar radiative forcing from the present to Maunder minimum ΔFP − M ~ 0.6 − 0.8 W / m2) or if the amplification of a weak direct solar forcing is substantial.
It was concluded that the TSI during the Maunder minimum was about 3 − 4 W / m2 less than at present, which translates into a solar radiative forcing1 ΔFP − M ~ 0.5 − 0.7 W / m2.
The role of stratospheric ozone in modulating the solar radiative forcing of climate.
Rind, D., J. Lean, and R. Healy, 1999: Simulated time - dependent climate response to solar radiative forcing since 1600.
The solar radiative forcing is TSI in Watts per square meter (W - m - 2) divided by 4 to account for spherical geometry, and multiplied by 0.7 to account for planetary albedo (Meehl 2002).
