Sentences with phrase «outgoing radiation to space»

The effect of the GHE is to move the average location of outgoing radiation to space up from the surface, and the equilibrium of solar input and radiation to space occurs at this average altitude.

The reason the air and water are warmer than they would be with no greenhouse gases (and thus have increased radiation both directions) is that the lapse rate combined with the high altitude of outgoing radiation to space gives a higher near surface temperature than otherwise.

The answer is yes, it slightly raises the location of outgoing radiation to space, and thus the lapse rate times the slight increase in altitude would raise the ground temperature.

CO2 is a greenhouse gas, and for a given increase in opacity the outgoing radiation to space will decrease at a given temperature (which has been observed in studies of radiant spectra).

My own prediction is that, as temperatures fail to increase over the next five years, attention will turn to Ray Ladbury's «bite» — the resonant absorption of outgoing radiation by CO2 and H2O in the radiation spectrum viewed from space.

Earth's energy balance In response to a positive radiative forcing F (see Appendix A), such as characterizes the present - day anthropogenic perturbation (Forsteret al., 2007), the planet must increase its net energy loss to space in order to re-establish energy balance (with net energy loss being the difference between the outgoing long - wave (LW) radiation and net incoming shortwave (SW) radiation at the top - of - atmosphere (TOA)-RRB-.

The imbalance is not between IR absorbed and IR emitted by a layer of atmosphere, but between the incoming shortwave solar energy from space and the outgoing longwave energy emitted to space, due to the increasing difference between the ground temperature and the temperature of the level from which re-emitted radiation can escape to space.

I think the central point is that of the scale of energy imbalance and the timescale for response: our addition of CO2 reduces outgoing thermal radiation, so incoming energy from the sun is greater than outgoing energy to space.

In the absence of solar heating, there is an equilibrium «skin temperature» that would be approached in the uppermost atmosphere (above the effective emitting altitude) which is only dependent on the outgoing longwave (LW) radiation to space in the case where optical properties in the LW part of the spectrum are invariant over wavelength (this skin temperature will be colder than the temperature at the effective emitting altitude).

Theory certainly suggests that a warmer atmosphere as a result of higher CO2 concentrations will emit photons more frequently — and more of these will by chance find a path to space restoring the conditional equilibrium between ingoing and outgoing radiation — the condition being that all other things remain equal.

The time scales involved remain miniscule on the level of an individual molecule BUT on a planetary scale they become highly significant and build up to a measurable delay between arrival of solar radiant energy and its release to space as outgoing radiation.

Rising water vapor content, particularly in the upper troposphere greatly reduce the amount of outgoing longwave radiation (OLR) which can escape to space.

The resulting extra increased upper tropospheric moisture is assumed to block large amounts of additional outgoing infrared (IR) radiation to space beyond the blockage of CO2 by itself.

An atmosphere that is perfectly transparent to incoming and outgoing radiation can not radiate and all its heat content comes from conduction from the surface and is transported through the atmosphere solely by convection with no loss of energy to space except for the tiny fraction of atoms at the top of the atmosphere that exceed escape velocity.

Tom Vonk is correct when he says that the following statements are over-simplifications and need corrections (in caps): «CO2 absorbs AND EMITS the outgoing infrared energy and warms the atmosphere TO A HIGHER TEMPERATURE THAN IT WOULD HAVE WITHOUT CO2» — or — «CO2 traps part of the infrared radiation between ground and the upper part of the atmosphere» AND IS THE MAJOR SOURCE OF INFRARED RADIATION FROM THE UPPER ATMOSPHERE radiation between ground and the upper part of the atmosphere» AND IS THE MAJOR SOURCE OF INFRARED RADIATION FROM THE UPPER ATMOSPHERE RADIATION FROM THE UPPER ATMOSPHERE TO SPACE.

Increased concentrations of greenhouse gases, such as CO2, reduce the amount of outgoing longwave radiation (OLR) to space; thus, energy accumulates in the climate system, and the planet warms.

Over millions of years the earth has arrived at a temperature balanced between incoming solar energy and outgoing radiation of energy to space.

2) Resistance to outgoing longwave radiation reduces due to a weaker inversion at the tropopause, energy is lost to space faster whilst the stratosphere cools.

Add GHG to the atmosphere and some of the outgoing radiation will be intercepted and prevented from reaching space.

Thus the night sky is frequently clear, allowing any outgoing radiation from the tropical ocean a more or less free ticket to outer space.

«Effect» is here defined in terms of radiative forcing (RF), which is (loosely) the change in the amount of incoming (to Earth) versus outgoing (to space) radiation / energy, measured in watts per square metre (w / m2).

2: Resistance to outgoing longwave radiation reduces, energy is lost to space faster.

«The Planck feedback parameter [equivalent to κ — 1] is negative (an increase in temperature enhances the long - wave emission to space and thus reduces R [the Earth's radiation budget]-RRB-, and its typical value for the earth's atmosphere, estimated from GCM calculations (Colman 2003; Soden and Held 2006), is ~ 3.2 W m2ºK — 1 (a value of ~ 3.8 W m2ºK — 1 is obtained by defining [κ — 1] simply as 4σT3, by equating the global mean outgoing long - wave radiation to σT4 and by assuming an emission temperature of 255 ºK).»

The same is true at the top of the atmosphere where the outgoing longwave radiation to space is also unidirectional.

A recent paper by Lindzen and Choi in GRL (2009)(LC09) purported to demonstrate that climate had a strong negative feedback and that climate models are quite wrong in their relationships between changes in surface temperature and corresponding changes in outgoing radiation escaping to space.

I get that incoming and outgoing radiation energy must balance and that radiation is the only way the Earth could come to equilibrium with the Sun and space.
