Sentences with phrase «radiations from sun then»

So, here is my newbie question: Fig 1 shows earth receiving higher levels of infrared radiations from sun then the infrared radiation emitted by earth.

Not exact matches

If the amount of energy received by the Earth from the Sun exceeds the amount the Earth radiates into space, then the only thing the Earth can do is increase its temperature, which in turn will increase the amount of radiation into space.

Now, when the energy received directly from the Sun at the surface of Venus is less than 10 % of what we receive on Earth, then there is less than 10 % coming back as back radiation — far less in fact.

The Earth receives energy from the Sun in the form of visible light and ultraviolet radiation, which is then re-radiated away from the surface as thermal radiation in infrared wavelengths.

If CO2 and H2O molecules now are cooled below the previous equilibrium point by having their radiation allowed to escape to outer space, then I believe these molecules must then tend to absorb more energy than yield energy with each interaction with the other components of the atmosphere until that atmosphere as a whole reaches a new thermal equilibrium where the net radiation going out and the net radiation coming in (primarily from the sun and the surrounding atmosphere) is the same.

Then, for the benefit of the lay reader, who would not be expected to understand the clear (to a competent physical scientist) implication of this simply - stated fact, I wrote: «This in fact indicates that the Venusian atmosphere is heated mainly by incident infrared [not the VISIBLE portion, which is indeed largely reflected, defenders, but INFRARED] radiation from the Sun, WHICH IS NOT REFLECTED BUT ABSORBED [or allowed in to heat the lower atmosphere] by Venus's clouds, rather than by warming first of the planetary surface.

If so, then we can put numbers behind the qualitative discussion on the influence of CO2 on the climate of the Earth since we can now relate the additional heat available due to the absorption of the outgoing radiation by CO2 to the total heat available due to the irradiation from the Sun and the back radiation previously to the enriching of the atmosphere by CO2.

If the Sun were a massive ball of hydrogen, heated by a H - fusion reactor at its core, then changes at the solar core would be delayed by about 30 My (million years), the diffusion time for radiation from the core of the Sun to its surface [See William A. Fowler, «What cooks with solar neutrinos?»

In so far as the air circulation fails for a time to maintain temperature stability then radiation from surface to space will also change but in due course stabilty is always restored between the four said parameters (sea surface / surface air / sun to sea / air to space).

@Toneb if Earth «is losing exactly the same amount of radiation that it is receiving (from the Sun)», then gained heat is ZERO.

One suggestion he came up with was that the energy coming in from the sun in the form of visible and ultra-violet light (known back then as «luminous heat») was easily able to pass through Earth's atmosphere and heat up the planet's surface, but that the «non-luminous heat» (now known as infra - red radiation) then emitted by the Earth's surface could not make it back in the opposite direction quite so readily.
