Sentences with phrase «surfaces radiate heat»

To say it a bit worse but in modern lingo: to maintain radiative equilibrium, the planet has to put out a certain amount of heat, and if it can't radiate it out from the surface, the lower atmosphere somehow has to get warmer until there's some level that radiates the right amount.

Some of the latent heat carried from the surface to the upper troposphere is radiated to space.

Are the episodes thought to be actual changes in the amount of heat being radiated by the planet (because the surface of the ocean gets warmer and cooler, does the actual infrared flux from the top of the atmosphere then change as a result)?

These can transfer as much heat in a day from the surface into the troposphere where it is radiated to space, as the all of mankind uses in a year.

With climate and Greenhouse Gas thoeries of Global warming, it appears to me that of most interest is the interface between the Earth's atmosphere and space and the flow of radiated heat from the sun, what's reflected back from Earth's surface and the consequences of any change in that balance.

In other words, greenhouse gases don't retain heat themselves, but rather redirect outgoing energy radiated by the surface and lower in the atmosphere, thereby delaying it's ultimate escape to space.

A second alternative acknowledges an unchanging OLR, but posits that less is now entering the stratosphere in wavelengths absorbable by CO2 because a heated surface is now radiating more IR to space in wavelengths where CO2 does not absorb («window regions»).

Heat radiated from the Earth's surface has a range of frequencies, which encompass the vibration frequencies of the gases in the atmosphere, including those of greenhouse gases such as carbon dioxide.»

Is the heat simply going into melting the surface ice or is it radiating into space?

But the monthly fees are going to be extraordinary - all that extra surface to maintain (and radiate heat), acres of terrace on top of habitable space, everything you are taught in architecture school and in the harder school of actually building things that you shouldn't do.

If the DLR decreases, the temperature gradient between the surface skin and bulk increases, and more heat flows from the ocean depths to the surface where it is radiated away.

As the Sun radiates heat to the Earth, different surfaces absorb the heat energy in different ways.

Dynamical upward transport by convection removes excess heat from the surface more efficiently than longwave radiation is able to accomplish in the presence of a humid, optically thick boundary layer, and deposits it in the upper troposphere where it is more easily radiated to space, thereby affecting the planetary energy balance.

7 Wind As the Sun radiates heat to the Earth, different surfaces absorb the heat energy in different ways.

«The sun's heat and light energy are constantly radiated from its surface in all directions.

1) Can the IR radiated by CO2 to the surface of the ocean that is captured as latent heat and transferred to the TOA via evaporation, be released at different wavelengths??

The total heat radiated from the planet is equal to the energy flux implied by its temperature, Te (from the Stefan - Boltzman law) times the entire surface of the planet or:

With adequate training they would be aware of the science that all of the radiant heat from the earthâ $ ™ s surface that is going to be absorbed by greenhouse gases gets absorbed close to the ground (half within less than 24 meters) and is carried up by convection currents to where it ultimately gets radiated to space.

Installing light shading structures over streets, pavements and roofs can reduce the surface temperature of materials, and reduce the heat absorbed and radiated back into streets.

Most of the heat radiated by the surface is absorbed by trace gases in the overlying atmosphere and re-emitted in all directions.

CH, what percentage of heat is added to the atmosphere by burning compared to that added from hot sunlit surfaces, or the latent heat from all the oceans, or radiated heat from the ground?

Heat radiates to space from the ice sheet surface.

The outer surface of a blanket is colder than that of a thin one and so radiates less heat away.

As increased levels of greenhouse gases such as carbon dioxide trap more solar heat radiating from the Earth's surface, less warmth reaches the stratosphere, which cools as a result.

Basically, as fast as heat loiters about on our planet's surface, it either radiates off to space or Water will pick it up and carry it to the upper layers of our atmosphere, where it will change form from gas to liquid or solid giving off heat to space while being super cooled at the same time.

The rate of temperature increase would be most noticeable in the tropics because that is where the surface would be radiating the most heat.

During a cooling phase, surface atmosphere could cool as heat is transported to upper atmosphere by more intense weather and then radiates away.

Part way there, but no quantitation yet: of the 3.77 W / m ^ 2 radiated back dowwnard, most goes to increased rate of evaporation of the water at the surface, and much less goes to increased mean temp increase at the surface; hence increased rate of non-radiative transfer of heat from surface to upper atmosphere, slight increase in rainfall as hydrological cycle is faster, and slight increase in cloud cover.

Satellite measurements show that this lowest layer of the atmosphere is warming as greenhouse gases build up and trap heat that radiates from the Earth's surface.
