Not exact matches

The sun's warming radiation drives circulation from the equator to the subtropics.

On Earth, temperature inversion occurs because ozone in the stratosphere absorbs much of the sun's ultraviolet radiation, preventing it from reaching the surface, protecting the biosphere, and therefore warming the stratosphere instead.

In many Mediterranean climates there is a strong diurnal character to daily temperatures in the warm summer months, due to the great loss of ultraviolet radiation from the sun at night.

Of course this is a global average but in principle I see no reason not to consider that some large percentage of the energy warming the tropical Pacific will be from «back radiation» (for which CO2 will be partly responsible) and thus not «direct from the sun.»

I ask because my limited understanding is that temperature is related to kinetic energy, but would not register an overall increase in potential energy, in which case energy from the sun could be partitioned in heat energy emitted from the planet and work used to increase potential energy, possibly allowing an energy balance that does not require a radiation balance, and also does not require a warming effect.

The temperature around the world is now increasing and TSI (Total Solar Irradiance) I think solar cycle can cause global warming because our temperature is increasing by radiation from the sun which comes from solar cycle too.

Surface temperature is an imperfect gauge of whether the earth has been warmed by an imbalance between incoming radiation from the sun, and outgoing radiation, because of the role of ocean currents in the distribution of heat between deeper and surface waters.

Waters at this depth can not be warmed directly by the sun or greenhouse effect as solar radiation penetrates only to 100 metres depth, while infra - red radiation from the greenhouse effect can only warm the immediate surface «skin» of the ocean.

To me, it is more likely the fluctuation in E-UV coming from the sun that causes the warming and cooling effects by changing the reactions that are happening on TOA, i.e. O3, HxOx and NOx are rising now, causing more back radiation of F - UV, meaning less energy going in the oceans.

So we can blame the sun for the Holocene period, but even though solar radiation has increased right along with the temperature in the 20th century, we are assuming that the warming is due to the minute increase of atmospheric CO2 from humans?

The heat capacity of the ocean is 1,000 x greater than the atmosphere, ocean is over 70 % of earth's surface and earth is warmed by radiation from sun and GHE.

At one point Dr. Chu thought that painting roofs and other structures white would help reflect the sun's radiation and save the nation and the world from global warming.

ok myrrh, if the only radiation that comes from the sun is visible light that can not warm us, why does standing out in the sun feel warm?

Seems everyone agrees A — the earth is warmed by infrared radiation directly from the sun, which is thereby absorbed, converted into heat energy.

Myrrh, unless you can show that radiation from the sun does not warm the earth, you are wasting your time, just spouting junk - science.

Memphis October 16, 2012 at 1:43 am Myrrh So you are nowfinally going to stop pretending that radiation from the sun can not warm us?

B — the earth is not warmed by the visible radiation from the sun.

What I am saying, listen carefully now, is that the radiation from the Sun which actually warms you is [DRUM ROLL] invisible!

In fact, on average through day and night and over a whole year over the whole Earth's surface, downward infrared radiation is more important than downward solar radiation from the Sun in warming the surface.»

Earth's atmosphere also plays a vital role in regulating the temperature by providing a blanket of gases that not only protects us from excessive heat and harmful radiation from the sun, but also traps heat rising from the Earth's interior, keeping us warm.

Global warming starts with the greenhouse effect, which is created by the relationship between the radiation from the sun and the Earth's atmosphere.

And this is what really supplies the necessary thermal energy to supplement the Sun's energy entering Earth's surface, not back radiation which can't transfer thermal energy from a colder troposphere to a warmer surface.

This must result in about 85 times as much infrared radiation from the Sun, at 3.3 microns wavelength, being sent back into space by the absorption and re-radiation from methane molecules in the upper atmosphere as could be re-radiated into the lower atmosphere for infrared radiation sourced from the warmed Earth.

When SW radiation from the Sun interacts with matter (the Earth, for example) it imparts energy to the receiving molecules which can increase the thermal energy of the matter — it fills the «energy gap» required to reach the next energy level (warm).

The light from the Sun passes through the Earth's atmosphere, which is transparent to visible light (that's why our eyes evolved to be sensitive to this kind of electromagnetic radiation), and warms the surface of the Earth, which in turn reradiates the energy, now as infrared radiation, because the Earth's surface isn't as hot as the Sun.

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.

«This H2O negative - feedback effect on CO2 is ignored in models that assume that warm moist air does not rise and form sunlight - reflecting clouds, but remains as humid air near sea level, absorbing infrared radiation from the sun, and approximately doubling the temperature rises predicted from atmospheric CO2 increases.

You also have to bear in mind that UHI isn't just about having the potential to artificially raise maximum temperatures, but more significant is the effect it has on reducing the extremes of night time minimums; sun - warmed asphalt / concrete, radiation from warm buildings and warm air from AC vents are the key to the UHI effect.

northern Scandinavia) cloudy days in November and December are typically warmer than cloud - free days because the Earth's surface has a net radiation loss at the time (i.e. outgoing heat loss exceeds radiation received from the sun).

That is proof that the longwave radiation from the Earth has reached to the Sun and some of it will impact into the Sun and, ever so slightly, warm it.

Clouds can have a double effect on radiation: they warm the earth by reducing the amount of radiation from the earth that escapes into space but also cool the earth by reflecting the sun's rays back into space.

Now the sun would be expected to set up an undisturbed gradient from cold at the bottom to warm at the top but it does not because upward radiation from the surface plus energy drawn upwards by evaporation at the surface creates a layer 1 mm deep near the surface (the subskin) which is 0.3 C cooler than the water below it.

I didn't mention the obvious fact that you stated, that the heating will cease, when the upper atmosphere warms enough to restore the equilibrium between radiation leaving the earth and arriving from the sun.

However, the point is simply this: As long as you have an IR - absorbing atmosphere that is at a nonzero temperature, the earth's surface will have to be at a warmer temperature (in order to radiate away the energy that it receives from the sun) than it would be if the atmosphere did not absorb any of the IR radiation that the earth emits.

By capturing thermal radiation (heat energy emitted from the earth's surface components and re radiating it in all directions — part of the same process that is accepted (somewhat like the «earth revolves around the sun accepted») to keep the planet much warmer than it would otherwise be in the absence of any of these molecules — it actually «cools.»

It is most correct to say that because of back - radiation (in combination with the radiation from the sun), the earth is warmer than it would be if all the radiation from its surface escaped into space.

The downturn in temperature since the 1940s, whether due to a variation in the Sun's radiation or some other natural cause, could indeed change to a natural upturn that would add to greenhouse warming instead of subtracting from it.

Past interglacial warming were triggered by sharp spikes in solar irradiation associated with the Earth's position relative to the sun (Milankovic cycles), with consequent feedback release of greenhouse gas (CO2, CH4) from the oceans and the biosphere, resulting in atmospheric infrared radiation effects and in melting of ice sheets, which amplify global warming.

To understand why our climate warms or cools we need to know how much radiation is coming in from the sun and how much the earth is radiating out into empty space.

Nice theory, but, a large part of the UHI effect is retained heat from insolation (incoming solar radiation energy warming concrete etc) and, if no sun, no warmth... which in large part happened in Dallas Ft. Worth just recently with our record snow; and we had continuing overcast afterwards too.
