Sentences with phrase «radiation from the atmosphere increases»

Not exact matches

This consequence would follow from the increase in ultraviolet radiation allowed to penetrate through the upper atmosphere.

The longwave radiation from the cloud - free atmosphere can only increase due to increasing surface temperature or due to increasing greenhouse gases, who additionally close the window.

For example, they predicted the expansion of the Hadley cells, the poleward movement of storm tracks, the rising of the tropopause, the rising of the effective radiating altitude, the circulation of aerosols in the atmosphere, the modelling of the transmission of radiation through the atmosphere, the clear sky super greenhouse effect that results from increased water vapor in the tropics, the near constancy of relative humidity, and polar amplification, the cooling of the stratosphere while the troposphere warmed.

Second even if we ignore convection (and assume all warming of the atmosphere is from below, ie no incoming solar radiation is absorbed in the atmosphere) it is not the case that the atmosphere temperatures will «pivot» around some fixed level (increasing below it and falling above it).

Absorption of thermal radiation cools the thermal spectra of the earth as seen from space, radiation emitted by de-excitation is what results in the further warming of the surface, and the surface continues to warm until the rate at which energy is radiated from the earth's climate system (given the increased opacity of the atmosphere to longwave radiation) is equal to the rate at which energy enters it.

The point is that as long as greenhouse gases are reducing the rate of radiation from the land oceans and lower atmosphere, there may be no distribution of the net energy increase that results in good news.

The imbalance is not between IR absorbed and IR emitted by a layer of atmosphere, but between the incoming shortwave solar energy from space and the outgoing longwave energy emitted to space, due to the increasing difference between the ground temperature and the temperature of the level from which re-emitted radiation can escape to space.

Less TOA cooling will occur if bands are placed where, in the upper atmosphere or near TOA, they absorb more of the increases in radiation from below from surface + tropospheric (+ lower stratospheric) warming.

Starting with small amounts of absorption, the transient cooling should extend through most of the atmosphere (except the troposphere) because each layer's emission and absorption of radiation from the surface would increase equally if not for the increased absorption of radiation from the surface by lower layers, while the increased absorption of radiation from other layers would be a smaller effect due to the small emissivities — this would be true in the troposphere as well except the convective coupling with the surface would prevent it.

More importantly, it isn't just the surface that is adjusting its outgoing radiation to the increased CO2, but the entire troposphere, and most of that radiation is emanating from the high atmosphere.

Is the majority of the initial (before feedback) atmosphere heating resulting from increased CO-2 reduced by the fact that the majority (W - Sq - M at low latitude) of outgoing radiation is in the latitudes most saturated by water vapor?

The effect of more CO2 is an insignificant increase in the radiation emitted from the coldest, lowest radiance layer of the atmosphere, «too tiny to matter.»

Increased amounts of gases such as carbon dioxide make the atmosphere absorb long - wavelength radiation from the surface more strongly and also emit more radiation back down towards the surface.

This is the portion of temperature change that is imposed on the ocean - atmosphere - land system from the outside and it includes contributions from anthropogenic increases in greenhouse gasses, aerosols, and land - use change as well as changes in solar radiation and volcanic aerosols.

So the increase in emission to the surface from the increased CO2 is nearly balanced by decreased transmission of solar radiation through the atmosphere.

Increased atmospheric CO2 tends to close this window and cause outgoing radiation to emerge from higher, colder levels, thus warming the surface and lower atmosphere by the so called greenhouse mechanism»

As a greenhouse gas, this increase in atmospheric CO2 increases the amount of downward longwave radiation from the atmosphere, including towards the Earth's surface.

The atmosphere's opacity increases so that the altitude from which the Earth's radiation is effectively emitted into space becomes higher.

A sea surface temperature increase in the tropics would result in reduced cirrus clouds and thus more infrared radiation leakage from Earth's atmosphere.

Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other greenhouse gases) absorb the infrared radiation from the Earth's surface.

If that point is known (yes I know it won't be a sharpt break between convection and radiation, but let's keep it simple), then the equation above can be used to find the increase in surface temperature resulting from an isentropic near surface atmosphere.

Is it transport of energy into the atmosphere by transpiration, or the increased downwelling radiation from an increased amount of water in that atmosphere?

Further evidence for forced changes arises from widespread melting of the cryosphere, increases in water vapour in the atmosphere and changes in top - of - the atmosphere radiation that are consistent with changes in forcing.

They combined simple energy balance considerations with a physical assumption for the way water vapour is transported, and separated the contributions of surface heating from solar radiation and from increased greenhouse gases in the atmosphere to obtain the two sensitivities.

For example, in a warmer climate, more water vapor is evaporated into the atmosphere and since water vapor is a greenhouse gas in the sense of absorbing IR radiation, this is a positive feedback, in essence increasing the W / m ^ 2 from that due to CO2 alone.

One of the important points for the actual dispute is if the increase of evaporation from the surface of the oceans prevents the rise of temperature of oceans, which would be expected due to the increase of the back radiation (which, in turn, is due to the change of the composition of the atmosphere).

Increase the optical thickness of the atmosphere and you raise the effective height from which radiation tends to escape the atmosphere without being re-absorbed.

In other words, * we can observe the increase of CO2 in atmosphere above the ocean, * CO2 absorbs some part of the outgoing radiation from the surface of the ocean which increases somewhat the temperature of the air * The increasing of temperature causes the (slight) increase of the (already existing) back radiation * This (now increased) back radiation is absorbed by the surface skin layer of the ocean which means that the energy delivered by the back radiation to the surface skin layer is now slightly higher * This additional energy will now be distributed over the channels that are participating in the heat transfer from the absorbing surface skin layer to both the air above the skin layer and the bulk of the ocean.

Anthropogenic global warming is caused by an increase in the amount of downward longwave infrared radiation coming from greenhouse gases in the atmosphere.

Net result of all this Photon energy from 15um Earth surface up going to increase in temperature of atmosphere and increasingly more radiation in wavelengths > 15um.

That induces an increase in insolation (~ 2 W / m2) directly absorbed in the oceanic surface, and an increase in IR radiation (~ 5 W / m2) back to space (from anywhere in the atmosphere or surface).

If so, why doesn't increasing CO2 reduce some of that radiation from getting thru the atmosphere — or maybe it does?

KIA: If the atmosphere is warming, by what amount, if any, is radiation from the earth to space increasing?

If the atmosphere is warming, by what amount, if any, is radiation from the earth to space increasing?

All the energy stored in the atmosphere is sensible heat above the top of the troposphere, and increasing the CO2 content there increases the amount of radiation to space more than it increases the likelihood of absorption of IR from below, so the stratosphere cools — this has been observed.

«The Planck feedback parameter [equivalent to κ — 1] is negative (an increase in temperature enhances the long - wave emission to space and thus reduces R [the Earth's radiation budget]-RRB-, and its typical value for the earth's atmosphere, estimated from GCM calculations (Colman 2003; Soden and Held 2006), is ~ 3.2 W m2ºK — 1 (a value of ~ 3.8 W m2ºK — 1 is obtained by defining [κ — 1] simply as 4σT3, by equating the global mean outgoing long - wave radiation to σT4 and by assuming an emission temperature of 255 ºK).»

Such an increase is seen in the reanalyses, and the outgoing long - wave radiation has become more diffuse over time, consistent with an increased influence of greenhouse gases on the vertical energy flow from the surface to the top of the atmosphere.

All that might happen is that an increase in atmospheric temperature might decrease conduction from the surface and also decrease the net radiation from the surface into the atmosphere (ie increase the back radiation from the atmosphere).
