Sentences with phrase «of water vapour decreases»

Not exact matches

Indeed, there is a clear physical reason why this is the case — the increase in water vapour as surface air temperature rises causes a change in the moist - adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).

This is synonymous to a decrease in the transfer of water vapour.

And the other sort of latent heat, a decrease in atmospheric water vapour is also the stuff of fantasy requiring a change of 50,000 cu km when the atmosphere only contains (and only can contain) ~ 13,000 cu km without crazy temperature increases.

The Met Office held a briefing for the press to explain that the reduction in warming might be natural variation, or could be accounted for by a mixture of a decrease in stratospheric water vapour and the cooling bias introduced by new methodology.

[41] The water vapour content of the air between the top of the air and the altitude of pressure P (atm) is decreasing roughly like P4.5 [42]: hence 80 % of the total water vapour is between P = 1 and P = 0.75 near 2.3 km, and the total water content of the air closely follows the surface temperature.

Simulations with GCMs by Stevenson et al. (2000) and Grewe et al. (2001) for the 21st century indicate a decrease in the lifetime of tropospheric ozone as increasing water vapour enhances the dominant ozone sink from the oxygen radical in the 1D excited state (O (1D)-RRB- plus water (H2O) reaction.

The water vapour content of the air has been roughly constant since more than 50 years but the humidity of the upper layers of the troposphere has been decreasing: the IPCC foretold the opposite to assert its «positive water vapour feedback» with increasing CO2.

Truth n ° 10 The water vapour content of the air has been roughly constant since more than 50 years but the humidity of the upper layers of the troposphere has been decreasing: the IPCC foretold the opposite to assert its «positive water vapour feedback» with increasing CO2.

That would be aided by the changes in altitude of water vapour since the mid 1990's, where lower stratosphere and upper troposphere water has decreased, and mid-lower troposphere water vapour has increased.

Or what the possible role of increasing / decreasing water vapour content in increasing / decreasing the radiative forcing with multi-decadal oscillations?

Three analyses of the NASA NVAP satellite data show little or no empirical correlation between either surface temperature or atmospheric carbon dioxide concentration, Solomon et al in fact shows a 10 % decrease in stratospheric water vapour in the decade pre-2000.

Linear regression provides some evidence of a small rapid negative response in the LW from water vapour, related largely to decreased relative humidity (RH), but the response here, too, is dwarfed by subsequent response to warming.

Total water vapour in the atmosphere may increase as the temperature of the surface rises, but if at the same time the mid - to upper - level concentration decreases then water vapour feedback will be negative.

Future climate change may cause either an increase or a decrease in background tropospheric ozone, due to the competing effects of higher water vapour and higher stratospheric input; increases in regional ozone pollution are expected due to higher temperatures and weaker circulation.

Adding water vapour to the surface layer increases Eu, but adding the same amount of water vapour to the upper layer decreases Eu.

Due to «climate cell convection», and the property of being lighter than air, a «water vapour» (WV) molecule finds itself rising to increasing altitudes through the «adiabat» (as altitude increases the temperature of an «adiabatic atmosphere» decreases) of the troposphere.
