Sentences with phrase «long wave radiation as»

Of course, there are plenty of negative feedbacks as well (the increase in long wave radiation as temperatures rise or the reduction in atmospheric poleward heat flux as the equator - to - pole gradient decreases) and these (in the end) are dominant (having kept Earth's climate somewhere between boiling and freezing for about 4.5 billion years and counting).

Not exact matches

At present, metamaterials work best for longer - wavelength radiation such as radio waves and microwaves, which require elements that are on the order of tens of millimeters.

Perhaps there is room for more indicators inspired by the «big picture physics», such as the planetary energy balance and the outgoing long - wave radiation (OLR).

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-.

In equilibrium to maintain the energy balance of the earth you must have just as much long wave radiation passing through (and warming) the top layer as before.

The work is an estimate of the global average based on a single - column, time - average model of the atmosphere and surface (with some approximations — e.g. the surface is not truly a perfect blackbody in the LW (long - wave) portion of the spectrum (the wavelengths dominated by terrestrial / atmospheric emission, as opposed to SW radiation, dominated by solar radiation), but it can give you a pretty good idea of things (fig 1 shows a spectrum of radiation to space); there is also some comparison to actual measurements.

As an aside, the radiative forcing by aerosols (in both long wave and solar radiation at the tropopause) is not the same as global dimming (which is a solar radiation effect at the surface) though they are relateAs an aside, the radiative forcing by aerosols (in both long wave and solar radiation at the tropopause) is not the same as global dimming (which is a solar radiation effect at the surface) though they are relateas global dimming (which is a solar radiation effect at the surface) though they are related.

In reply to # 1, greenhouse gases absorb selective bands of radiation in the atmosphere and re-radiate them in all directions as longer wave infrared.

Despite the public focus on radiation risks, cost has long been the main obstacle to a substantial expansion of nuclear power generation, and will be even more as a result of Japan's still - unfolding effort to secure the wave - ravaged Fukushima Daiichi complex.

I have asked a few oceanologists about skin effect and downward mixing of energy from short and long wave radiation, but there seem to be as many opinions as there are oceanologists.

Although the Oxygen, Nitrogen and Argon components are warmed by conduction and convection they do not absorb the long wave radiation emitted by the surface and by the atmosphere as a whole.

As the earth is a sphere due to the geometry of a sphere, the highest amount of TSI the earth receives is at the equator and the highest amount of long wave radiation emitted to space is hence also at the equator.

As to the absorption of long - wave radiation from the earth's surface, while it may be true that carbon dioxide and water together do absorb certain frequency ranges of that radiation, I don't think that that matters a whole lot because most of the heat from the surface is transported to the top of the troposphere by conduction, convection and latent heat of vaporization of water during the day.

Maybe you don't believe that website, so here is better one: From: http://www.temis.nl/products/o3tropo.html «Ozone in the upper troposphere acts as a greenhouse gas by absorbing long - wave terrestrial radiation.»

As long as the outgoing longwave radiation is n`t decreasing over the Top Of Atmosphere, all the heat uptake comes from the change of short wave radiatioAs long as the outgoing longwave radiation is n`t decreasing over the Top Of Atmosphere, all the heat uptake comes from the change of short wave radiatioas the outgoing longwave radiation is n`t decreasing over the Top Of Atmosphere, all the heat uptake comes from the change of short wave radiation.

The internal kinetic energy is taken as the upward long wave energy flux at the top of the atmosphere, and the potential energy is the upward radiation flux from the surface.

Roy Spencer's thoughtful and well - considered explanation of how a colder body adjacent to a warmer body can make that warmer body warmer still is excellent, as is Jack Barrett's paper explaining the behaviour of greenhouse - gas molecules at the quantum level when they interact with long - wave radiation at their characteristic absorption wavelengths (their «absorption bands»).

As I see it the Earth is always going to be bathed in sunlight, some of this will be consumed by plants and so maintain our oxygen rich atmosphere, maintain the various nutrient cycles, carbon, nitrogen, oxygen, sulphur, e.t.c., and also excrete long wave radiation.

A real insulator such as Styrofoam, works on the long wave radiation, the same as CO2 and water vapor.

Now we know that as the earth is a sphere the tropical region of the planet receives the most amount of short wave radiation and hence also emits the most amount long wave radiation.

As this radiation heats the earth's surface, it escapes the earth in the form of long - wave radiation; a type of radiation that is much more difficult to pass through the atmosphere.

Please do not drag in the «red herring» of long wave IR radiation, there is just as much IR energy exchange going on in caves as out in the fresh air.

However when it comes to the «conundrum» as to why the Troposphere cools, with height, the Stratosphere warms, the Mesosphere cools and the Thermosphere warms I think we shall have to take into consideration that there are two types of «radiation» i.e. «Ionizing» and «Non Ionizing» Ionizing is «short Wave as in solar incoming radiation that has enough energy to dilsodge electrons, non ionizing (long wave) has not got enough energy for that kind of behaviour and is the kind of radiation discussed amongst the (us) global warming pundits.

«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).»
