Sentences with phrase «surface radiating»

Yet the period of rotation — obviously a major factor in explaining the loss of energy by a surface radiating to space — the Moon and Mercury for example have similar minimum temperatures — does not seem to have any place in this discussion yet it is one of the few real facts about planetary surface temperatures and heating and cooling we have.

Besides, different surfaces radiate different amounts of heat at infrared wavelengths owing to a material characteristic known as emissivity.

The highly saturated surfaces radiate with translucent layers of color.

«Sunlight passes through the atmosphere largely unhindered and warms the Earth's surface; the warmed surface radiates heat and some of this radiation is absorbed in the upper atmosphere and re-emitted, about half of the re-emitted energy returning to the Earth's surface.

To put it another way, while he surface itself radiates approx as T ^ 4, the almost balancing back radiation also increases as T ^ 4.

Funny thing about water, it ain't land:) about 70 % of the surface radiates at ~ 425Wm - 2 and has to release 334 Joules per gram to become not water:) The other model, about 30 %, has an average surface that radiates at 307 to 316 Wm - 2.

So if the atmosphere radiated more energy towards the surface would that not mean, according to your pseudoscience, that the surface radiated less energy to space.

The surface radiates more and more directly to space and its temperature gets determined directly by Stefan - Boltzmann law.

Further assume that the shell's internal and external surfaces radiate as a black body.

T ^ 4 effect, the hotter surfaces radiate much more proportionately than do the colder surfaces so basing a radiation budget on some fictional global average temeprature of 288 K is clearly not real.

If you agree with that, if the surface radiates more energy per second that it receives, do you agree that it should cool?

The warmed surface radiates as a blackbody, and also loses heat through rising in air currents or evaporated moisture.

The true situation is that without the green house gas the surface radiates to space which is at 4K while with ghg it radiates to to ghg at a temperature around 200K or higher.

As you are well aware (but some readers may not be) the wavelength a surface radiates is determined by its temperature.

Warmer surfaces radiate shorter wavelengths.

The surface radiates according to its temperature.

a) The surface radiates according to its temperature.

It is through temperature increase that the surface radiates more.

The surfaces radiate that heat as longwave (LW) energy or sensible heat (heat you can feel).

There is no question that the surface radiates LWIR.

«what does happen is that the water surface radiates away at about 400W / m ^ 2, in fact the top few microns will be cooler than the water a mm deeper because the transfer of heat from lower down (conduction, convection, diffusion etc.) is slower than the loss from the surface.»

Obviously that doesn't happen, what does happen is that the water surface radiates away at about 400W / m ^ 2, in fact the top few microns will be cooler than the water a mm deeper because the transfer of heat from lower down (conduction, convection, diffusion etc.) is slower than the loss from the surface.

The surface radiates ~ 400 Wm2, per the updated K & T diagram.

As to your questions, «Specifically, your earth model claims Absorbed Solar: 144.7 W / m ^ 2, when the surface radiates 144.7 W / m ^ 2 (224K) the atmosphere is (224K).

Not exact matches

The key to developing crispy browned surfaces on roasted cauliflower is baking in a superhot oven on the lowest rack so the baking sheet is close to the heat radiating off the bottom of the oven.

Continue to glue the candy canes to the wreath until the entire front surface is covered with candy canes radiating outward.

Dark city surfaces like roofs and roads absorb and radiate heat, leaving cities up to 3 °C hotter than surrounding areas.

Land surface temperature measures the heat radiated by land and vegetation.

As with a pulsar, the hydrogen releases energy as it slams into the surface, but unlike a pulsar, the hydrogen is more dispersed — so the X-rays released upon impact radiate outward much more diffusely.

But whereas the sun radiates more or less evenly across its entire surface, Betelgeuse has a 12,000 - degree hot spot that occupies about 10 to 20 percent of the star's disk — and baffles astronomers.

The next most abundant gases — water vapor and carbon dioxide — do absorb a portion of the infrared heat radiated by the earth's surface, thereby preventing it from reaching space.

In addition, the cold temperatures and the way air is mixed close to the surface at the poles mean that the surface has to warm more to radiate additional heat back to space.

It just so happens that this is the same as the amount of energy now being radiated from the sun's surface, even though those photons have taken 100,000 years to work their way from the core to the surface.

Spitzer was sent so far out because its delicate infrared - sensitive instruments must be kept at a frigid temperature just above absolute zero, and it is easier to maintain that temperature by operating far from the heat that radiates from the surface of our planet.

They may act as reflectors, bouncing incoming sunlight back into space, or like blankets, absorbing heat emitted from the surface and then radiating it back down.
