Sentences with phrase «solar heating of the planet»

In the case where there is a skin temperature that only depends on solar heating of the planet with no solar heating above the troposphere, an increase in GHG forcing would still result in upper atmospheric cooling, but this cooling would only be transient.

That could be crucial to learning much more: Jupiter was likely the first planet to form around the sun, so its inner workings — particularly the nature of its core and how heat trickles out from the planet's abyssal depths — may offer hints about how other planets came to be, both in our solar system and around other stars.

Short - duration flash - heating events in the solar nebula prior to the formation of planets in our solar system were responsible for supplying Earth with a presumably ideal amount of carbon for life and evolution.

But as the red dwarf is so tiny and cool, the exoplanet receives a similar amount of solar heating as our planet receives from the sun.

The general consensus among scientists is that the young Earth's atmosphere contained much larger quantities of greenhouse gases (such as carbon dioxide and / or ammonia) than are present today, which trapped enough heat to compensate for the lesser amount of solar energy reaching the planet.

Due to a rare aligning of all the planets that only happens once every 640,000 years, unprecedented solar flares release neutrinos that heat the earth's core to such a temperature that enormous volcanoes erupt across the globe and earthquakes so large that they can't even be considered earthquakes.

Greenhouse gases (which prevent dispersal of heat generated by the planet's surface, after this receiving solar radiation) of higher concentration on Earth are carbon dioxide (CO2), methane (CH 4), nitrous oxide (N2O), Compounds of chlorofluorocarbon (CFC) and water vapor (H2O).

As far as I know, if the only physical mechanism under consideration is the radiative cooling of the planet's surface (which was heated by shortwave solar radiation and reradiated at longer wavelengths in the infrared) via radiative transport, additional gas of any kind can only result in a higher equilibrium temperature.

As we know from laboratory experiments, mathematical calculations, and observations of Venus and other planets in the Solar System, greenhouse gases change things in two ways: they trap heat from the sun in the lower atmosphere, thus making the surface of the planet warmer; and they keep heat from rising, thus making the upper atmosphere colder.

The skin layer planet is optically very thin, so it doesn't affect the OLR significantly, but (absent direct solar heating) the little bit of the radiant flux (approximatly equal to the OLR) from below that it absorbs must be (at equilibrium) balanced by emission, which will be both downward and upward, so the flux emitted in either direction is only half of what was absorbed from below; via Kirchhoff's Law, the temperature must be smaller than the brightness temperature of the OLR (for a grey gas, Tskin ^ 4 ~ = (Te ^ 4) / 2, where Te is the effective radiating temperature for the planet, equal to the brightness temperature of the OLR — *** HOWEVER, see below ***).

This is why (absent sufficient solar or other non-LW heating) the skin temperature is lower than the effective radiating temperature of the planet (in analogy to the sun, the SW radiation from the sun is like the LW radiation, and the direct «solar heating» of the part of the atmosphere above the photosphere may have to due with electromagnetic effects (as in macroscopic plasmas and fields, not so much radiation emitted as a function of temperature).

A schematic of the solar system, where the energy received by the earth is the sunlight intercepted by its cross-section, and where the heat loss on average is due to thermal emission from the whole surface area of the planet.

The Solar variation, gravity and the Specific Heat Capacity of the atmosphere are the ONLY factors that effect the surface temperature profile of Earth and these type of planets!

It is «interesting» because it demolishes the greenhouse conjecture and then provides for the first time in world literature an explanation of temperatures and the necessary heat transfer mechanisms in all tropospheres, surfaces, crusts, mantles and cores of planets and satellite moons throughout the Solar System.

Climastrologists assumed the surface of our planet to be a near blackbody that could only heat to 255K for an average of 240 w / m2 of solar radiation if there were no radiative atmosphere.

Small changes in solar intensity lead to changes in all these elements which change the distribution of heat and rainfall and the reflectance — and thus the energy budget — of the planet.

The misnomer of the green house effect is at odds with reality, take a ride through our solar system and you will find that the heat of a planet has diddly squat to do with the composition of the atmosphere but its depth.

I mentioned years ago on this site that lag time effects of heating and cooling of the planet, both forward and aft from peak to trough of the solar cycle, exist as a result of solar variability.

This heat builds up after several decades and releases that excess over the following decades: cold then hot, cold again then hot again, these synods, also called grand planetary alignments, are of different strengths due to the varying perihelia and aphelia of the four gas giants, especially Jupiter which is the closest to the Sun and more massive than all other Solar System's planets and moons combined.

Extra heat from all sources — including the interior of the planet, fossil fuel burning, nuclear fission, solar radiance, north - south asymetry and — the big one — cloud radiative forcing — is retained in planetary systems as longwave emissions and shortwave reflectance adjusts to balance the global energy budget.

If the atmosphere of Venus became truly opaque to incoming solar radiation at some altitude above the surface, the atmosphere below that point would be isothermal assuming no heat input to the surface from the core of the planet.

But if you accept that the greenhouse effect is real, and that CO2 is a GHG, and that CO2 has increased (along with other GHGs), you have to accept the merit of my point: that solar, volcanoes, ocean currents and other natural variations do their thing, they vary, but GHGs exert a steady, constant upward forcing on temperature, which upward forcing is only offset by increased heat losses to space from a warmer planet.

«The ability of a planetary atmosphere to inhibit heat loss from the planet's surface, thereby enhancing the surface warming that is produced by the absorption of solar radiation.

It's twofold: No. 1, solar and wind power can not meet the world's voracious demand for energy, especially given the projected needs of emerging economies like India and China, and No. 2, nuclear power is our best hope to get off of fossil fuels, which are primarily responsible for the heat - trapping gases cooking the planet.

While these particles soon fall back down to Earth and allow the planet to heat up again, the thinking with so - called solar geoengineering is that this thin layer of reflective sulfate aerosols would be replenished to help keep it cool.

Clouds are important because they govern the balance between solar heating and infrared cooling of the planet, and thereby are a major control of Earth's temperature.

I understand the superficial attractiveness behind the proposition that the atmoshpere contains some gases that are largely transparent to incoming solar radiation and therefore the majority of this solar radiation finds its way through the atmosphere to the surface whereupon it heats the surface and this heat is, inter alia, radiated from the surface at a different wavelength at which wavelength the atmosphere (or some gases within the atmosphere) is not transparent such that some of this radiated enerrgy is «trapped» thereby effectively warming the planet.

The net flow of LW and latent heat is always from ocean to atmosphere and then to space when averaged across the planet, and the oceans receive the vast amount of their energy from SW solar.

As I understand it global temperatures are calculated as anomalies, thus removing seasonal swings, but that Heat Content is not, Now our dear planet has an elliptical orbit and is sometimes closer to the sun that others; sure, the shape of the land and oceans doesn't mean that the amount of incoming solar radiation falling on the oceans follows the Earths orbit, but it should be possible to work out the amount of incoming solar radiation each quarter.
