Sentences with phrase «in radiative characteristics»

A change in radiative characteristics alone does not make more energy available because solar insolation at TOA remains the same, mass stays the same and gravity stays the same.

ii) The real question is whether changes in radiative characteristics alone can result in energy being transferred from the radiative SDL to the mechanical AAL so as to add to the energy in that latterLoop and thereby significantly increase the temperature of atmosphere and surface by in turn increasing the time delay in the transmission of energy through the system.

iv) The answer must depend on whether any slowing down of the throughput of radiation from a mere change in radiative characteristics within the SDL would overwhelm the flexibility of the adiabatic processes in the AAL.

Not exact matches

It is the radiative characteristics of the atmosphere that here force ΔOHC not an increase in atmospheric temperature, prior or otherwise.

This essay is an attempt to link real world observations (the failure of surface temperatures to rise in tandem with atmospheric CO2) to basic physics and thereby show why the radiative characteristics of Greenhouse Gases can not increase the surface temperature of a planet when atmospheric mass, the strength of the gravitational field and the power of insolation at the top of the atmosphere remain the same.

Absent radiative warming it will still warm through conduction and convection and it will cool radiatively because all matter above absolute zero radiates and I'm pretty sure the nitrogen in our atmosphere is matter and it has a temperature above absolute zero therefore it radiates a continuous black body spectrum characteristic of that temperature.

The current impasse in climate science has arisen because AGW proponents say that simply altering the radiative characteristics of constituent molecules within the atmosphere can result in a change in system equilibrium temperature without any need for an increase in mass, gravity or insolation.

If anything else tries to disturb the temperature (or more accurately energy content) derived from those 3 characteristics alone then all one sees is a change in circulation adjusting the flow of energy throughput to keep top of atmosphere radiative balance stable.

Is this point only about the radiative characteristics of the H2O vapour, and the assumption that relative and / or specific humidity should rise thanks to CO2 - induced increased evaporation, which in turn would increase downwelling heat radiation — or just the part that slightly hotter surface (due to CO2) also emits more heat to be trapped by the vater vapour?

Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.

The strength of radiative cooling in turn depends on the characteristics of the clouds formed by the condensed vapor.

The case appears to be similar with some of the basics of the theory of human - caused climate change, too — basics, such as the radiative characteristics of CO2 and other «greenhouse» gases, or the importance of the greenhouse effect in the natural regulation of our planetary temperature, are firmly established.

Jensen, M.P., and A.D. Del Genio, 2003: Radiative and microphysical characteristics of deep convective systems in the tropical Western Pacific.

There are still questions about the assumed figures and also the emissivity and radiative characteristics of gases in our atmosphere.

The direct CO2 radiative forcing is the change in infrared radiative fluxes for a doubling CO2 (typically from 287 to 574 ppm), without any feedback processes (e.g. from changing atmospheric water vapor amount or cloud characteristics.)
