Sentences with phrase «clear sky greenhouse»

This sequence of events increases clear sky and incoming radiation while increasing the already dominant clear sky greenhouse effect from gaseous water vapor.

And I suppose if we aren't talking about the twilight effect, then the negative feedback won't be that negative if the clear sky greenhouse effect is becoming stronger with higher temperatures.

Not exact matches

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.

Maybe one could add instead: «This downward radiation from greenhouse gases (and some fine solid air particles («aerosols») e.g. can be measured at the surface in nights with clear sky and no other radiation sources in the atmosphere (e.g. Philipona and Dürr 2004 doi / 10.1029 / 2004GL020937).

I don't really understand the «clear sky super greenhouse effect» from Valero et al 1997, or in what way this cancel an Iris or Iris - like effect.

Even if clouds were decreasing there would be the clear sky super greenhouse effect where the rate at which downwelling thermal radiation grows relative to increasing temperatures is actually higher in the tropics than the rate at which surface thermal radiation emissions increase.

Re David L. Hagen December 27, 2013 at 6:49 pm at https://judithcurry.com/2013/12/20/open-thread-weekend-41/#comment-429721 You wrote re my question «What is the IR optical depth of the clear - sky part»: «Miskolczi is modeling the radiative absorption / radiation from ALL the greenhouse gas components of the atmosphere.

20 To a first approximation, the clear - sky greenhouse effect is proportional to the surface temperature.

The reverse effect of a more quiescent sun reduces direct solar warming and, by permitting the penetration of cosmic rays, facilitates low cloud formation, which increases reflection of already reduced solar radiation, reduces clear sky, reduces evaporation and simultaneously reduces the availability of the most important greenhouse gas, water vapor, through condensation and precipitation.

Note that this is only part of the story since, as far as we are aware, no one has yet investigated a counterintuitive parallel effect — condensation and precipitation will likely reduce the total lower atmospheric concentration of that ubiquitous greenhouse gas, water vapor, so increasing clear sky radiative cooling.

When considering the clear - sky greenhouse effect in the Earth's atmosphere or in optically thin planetary atmospheres, Eq.

My reply: — Clouds are not included in the clear - sky (cloudless) IR greenhouse gas absorption calculation (giving 80 % of the total, ~ 28 ° K), and at no rate are assumed to be constant.

Clouds are not included in the clear - sky (cloudless) IR greenhouse gas absorption calculation (giving 80 % of the total, ~ 28 ° K), and at no rate are assumed to be constant.

Water vapor accounts for the largest percentage of the greenhouse effect, between 36 % and 66 % for clear sky conditions and between 66 % and 85 % when including clouds.

A significant increase in the clear - sky longwave downward flux was found to be due to an enhanced greenhouse effect after combining the measurements with model calculations to estimate the contribution from increases in temperature and humidity.
