Sentences with phrase «additional water vapour»

And that additional water vapour would in turn cause further warming - this being a positive feedback, in which carbon dioxide acts as a direct regulator of temperature, and is then joined in that role by more water vapour as temperatures increase.

If two water filled pans are added on top of the two plates then additional water vapour will be added to the system, evaporating from the hot pan and condensing in the cold pan.

In such a cloud, the growth of a liquid water droplet to a raindrop begins with condensation, as additional water vapour condenses in a supersaturated atmosphere.

And that additional water vapour would in turn cause further warming - this being a positive feedback, in which carbon dioxide acts as a direct regulator of temperature, and is then joined in that role by more water vapour as temperatures increase.

Not exact matches

Recent observational and modelling evidence thus provides strong additional support for the combined water vapour - lapse rate feedback being around the strength found in AOGCMs.

If the enhanced atmospheric warming from a CO2 - induced temperature rise of 1 oC results in enhanced water vapour that gives an additional warming of say x oC, the overall warming (doubled CO2 + water vapour feedback; leaving out other feedbacks for now) will be something like 1.1 * (1 + x + x2 + x3...) or 1.1 / (1 - x)-RSB-.

You really need to account for the vertical structure of temperature (the lapse rate), and if you want your model to get a number of basic things right you need to include spectrally grey absorbers — plus the additional mixing in the troposphere (which depends on convection, and hence affects water vapour feedbacks) etc....

The additional atmospheric water vapour implies increased moisture availability for precipitation.

Water vapour is lighter than air once formed by the acquisition of the latent heat of evaporation so no additional radiative energy needs to be acquired to enable it to rise within the Earth's gravitational field.

An important one is additional poleward energy transport, but contributions from local high - latitude water vapour, cloud and temperature feedbacks have also been found.

As far as water vapor in the tropics, they even say» In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.»

In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.

As reported by the IPCC in the Physical Science Basis, «In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.

BH: Some of them are talking about climate sensitivity at 1.2 C, at 1.5 C. I think this is completely implausible because the basic energetics of the climate system responding to the additional greenhouse gas emissions almost from simple physics, has to be at least 1.2 C and possibly more before you begin to take into account any of the feedbacks in the system from water vapour in clouds and so on.

2) Methane emissions have a direct GHG effect, and they effect atmospheric chemistry and strat water vapour which have additional impacts

Methane is an important part of the anthropogenic radiative forcing Methane emissions have a direct GHG effect, and they effect atmospheric chemistry and stratospheric water vapour which have additional impacts natural feedbacks involving methane likely to be important in future — via wetland response to temperature / rain change, atmospheric chemistry and, yes, arctic sources There are large stores of carbon in the Arctic, some stored as hydrates, some potentially convertible to CH4 by anaerobic resporation [from wikianswers: Without oxygen.

Any additional atmospheric water vapour will only remain in the atmosphere for a few days before precipitating and restoring the previous balance.

Additional information on water vapour can be obtained from satellite observations and reanalysis products.
