Sentences with phrase «then radiates its heat»

Tons of concrete and asphalt soak up and then radiate heat, making city centers hotter by day — and by night.

While it's true that thick, beefy bodies of material can soak up heat during the day and then radiate that heat again when the air is cooler, this principle doesn't work if the thermal mass isn't insulated.

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.

If the matter retains its heat, then it will expand, becoming even sparser, and thus continue not to radiate much despite its growing temperature.

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)?

And I recall one can make ice in the desert the same way; a concentrating solar power plant could also create a «cold reservoir» by radiating heat away from some storage material at night, then dumping waste heat into that in the daytime, perhaps.

One is that the mechanism for the GHG warming is that the radiated energy from the air is absorbed by the GHGs to heat the GHG molecule to 900 + degrees, then the energy is released within microseconds and a few centimeters back to the air by collisions with the air, to return the air & GHGs to equilibrium temperature.

It is nature's way to transport huge amounts of latent heat directly to the upper atmosphere where it can then radiate directly to space.

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

The air and snow surface temperatures warm when storm clouds pass over the site, acting as a blanket that traps heat, and then they gradually cool as heat radiates to space after skies clear.

Pressurize gas, it heats up, and radiates heat, once cooled and then returned to ambient pressure and it's cooler [hence refrigeration and heat pumps - one could use flame of propane gas to provide the energy in order to refrigerate stuff [propane refrigerators need no electricity in order to power a compressor].

Such gases absrob heat energy through conduction and convection and then radiate the energy away, some of which is lost to space.

Then, as the day wanes and the air cools, it rains and all that latent heat radiates out through a less cloudy night sky.

So the first explanation for how this works, the original, is the now classic «greenhouse glass like barrier stopping longwave from the Sun from entering the atmosphere while visible travels through and is absorbed heating the Earth's surface which then radiates out thermal infrared, longwave.

And almost everyone else assumes that all visible light is only absorbed and then once heated from this absorption of energy, it radiates as blackbody [it emits energy according to it's temperature].

Once a gas is compressed and heated, it then radiates the excess heat away, until it achieves equilibrium with the surrounding environment.

Unless you are going to deny the earth heats the sun at all, then it makes no difference HOW the sun heats the earth, the result is the still the same — the earth then radiates all / some of this heat, which heats greenhouse gasses, which in turn return some of this heat to the earth.

Or if each day vast amounts of sunlight is absorbed, then vast amount of sunlight in a day must be radiates as heat.

Since it radiates both up and down, but is absorbing only from below (assuming no IR from above), then in the absence of additional heat transfer (by eg., conduction or convection), its absolute temperature would fall to ~ 0.84 Tsurface.

The Oceans store up heat near the equator, then pumps it poleward where the heat is radiated to space.

LIA wasn't GLOBAL cooling; but colder in Europe, north America — because Arctic ocean had less ice cover - > was releasing more heat / was accumulating - > radiating + spreading more coldness — currents were taking that extra coldness to Mexican gulf — then to the Mediterranean — because Sahara was increasing creation of dry heat and evaporating extra water in the Mediterranean — to top up the deficit — gulf stream was faster / that was melting more ice on arctic also as chain reaction — Because Mediterranean doesn't have enough tributaries, to compensate for the evaporation deficit.

WHEN more photons enter than leave, then that gas will heat up until it radiates away as many photons as it receives.

But then, you see, the impact crater cools, as the heat is radiated, convected, and conducted away.

If oxygen and nitrogen absorb heat, then clearly they radiate heat.

In those regions, thunderstorms carry heat from the surface miles upward, where it then radiates out into space.

The problem with the «not radiating» misstep is that it supports the notion that heat somehow «knows» whether or not it is aiming towards a hotter surface, then concludes it will not leave because it is hotter at the other end.

But if a little more energy is absorbed, then CO2 is acting like a little black soot in the atmosphere and it will, in turn, radiate more toward space as a black box would from the added heat and this might compensate for the change in albedo.

When the Arctic freezes over the ice insulates the sea and slows the heat loss from the N pole, when the Arctic ocean has less ice then more heat radiates off to space.

The AGW claim from the comic cartoon KT97 and kin The Greenhouse Effect says that Shortwave, (near UV, visible and near infrared, but mostly visible) heats up land and oceans, that no longwave infrared from the Sun gets through the invisible undefined and unexplained barrier said to be like the glass of a greenhouse, and then the Shortwave heated land and oceans radiate out longwave infrared, (which in real physics is heat, also called thermal infrared).

If the Sun is not the cause of the slight increases in average temperature observed and it is truly CO2 «trapping heat» then we have the unusual paradox of a system radiating less while it is warming.

The basic point and the one relevant to climate change, is still relevant — oceans still have an enormous moderating effect on temperature over time (though if there is a huge increase or decrease in re radiated atmospheric heat it is going to then affect the oceans initially).

Somehow, largely by conduction, convection and latent heat, and such means other than by radiation, heat flows from the earth's surface to somewhere, where it is then radiated into space.

adding a «radiating body» also add more conduction and then more heat lost.

If earth radiates 100 W / m ^ 2, then the shell will heat up and radiate 50 w / m ^ 2 inward and 50 w / m ^ 2 outward (it has twice as much area remember).

By contrast, when you have the shell there, then some of the heat that the planet radiates (actually, in this simple example where the shell is a perfect blackbody, all of that heat) is absorbed by the shell which subsequently radiates part of it back to the planet.

if an object radiates to an energy measured at 20C to a shell for a sufficent time to heat it to that temperature, then the shell isn't going to be 40C because radiation leaves it bi-directionally, 20C each way.

If the earth warms, then there is no balance, so the atmosphere can't radiate back to it, so the extra heat radiated from the earth and absorbed by the greenhouse gases must go elsewhere (e.g. convection) until such time as the atmosphere warms up to the new temperature.

Your coat then radiates some of that heat to the outside.

The heat was absorbed by the floor and then radiated into the room above.

If a significant portion of heat were being lost from the ocean, then it must warm surface air temperatures, before reaching the upper atmosphere and being radiated out to space.

Atmospheric carbon dioxide is the most voluminous of the so - called greenhouse gases that absorb heat radiated from the ground and then radiate some of it back to the Earth's surface, keeping the Earth warmer than it otherwise would be.

Paint over it or put tiles or parquet on top, then plug it in and it starts radiating heat without needing a difficult installation or taking up space.

The creation directly of Thermal IR heating to land and sea in raising the temperature of the Earth which then radiates out x amount of Thermal IR, and, the creation of heat from Life itself as it uses these different energies, including the Solar of the cartoon, to convert to chemical and mechanical uses which enable Life to flourish and in turn radiate out Thermal IR.
