Sentences with phrase «relative humidity results»

It's a function of temperature, so, for example, the same 70 percent relative humidity results from different amounts of water in the air.

Not exact matches

When the relative humidity is high, sweat drips off the skin so that the cooling benefit of evaporation is lost even at cooler temperatures, resulting in a build - up of body heat.

When they incorporated aerosol soot into the simulations, the resulting haze even more dramatically enhaced solar heating, thereby further increasing temperatures and lowering relative humidities.

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.

«It is now widely known that the water vapor feedback in general circulation models (GCMs) is close to that which would result from a climate ‐ invariant distribution of relative humidity [Soden and Held, 2006], as long anticipated before the advent of such models [e.g., Arrhenius, 1896; Manabe and Wetherald, 1967].»

The absolute humidity will be largely set by the oceans, so water vapor and will increase but relative humidity over land will largely decrease, resulting in less precipitation than one would otherwise expect, given Clausius - Clapeyron and a constant residence time.

Also Wentz neglects the fact that small changes in relative humidity or difference between surface and near air temperatures can result in large changes in evaporation rates based on their equation (1) which determines evaporation rate.

The higher temperature resulted in the air holding the water vapor longer, so absolute humidity in the lower troposphere did increase, but the relative humidity decreased.

Kiehl et al. (2000) improve the treatment of relative humidity compared to Kiehl and Briegleb (1993) and Kiehl and Rodhe (1995) by improving the relative humidity dependence of the aerosol optical properties and by using interactive GCM relative humidities rather than monthly mean ECMWF analyses, resulting in a larger normalised radiative forcing.

Nevertheless, it may be difficult to extrapolate our results to natural conditions as we (1) have not considered potential changes in biotic interactions (Sentis et al., 2013), (2) did not quantitatively assess changes in host plant quality due to heat stress and only included low relative humidity as an additional factor (Bauerfeind and Fischer, 2013a), (3) did not consider effects of different host plants (Bauerfeind and Fischer, 2013b), and (4) did not apply temperature variation in the adult stage.

Of course it does not agree with IPCC, who is selling us the message that specific humidity increases in march - step with temperature according to Clausius - Clapeyron to essentially maintain a constant relative humidity (thereby resulting in a major positive feedback from water vapor with warming).

The lower relative humidity and increased temperatures that would result from potential reductions in fog and low cloud cover could increase plant evapotranspiration rates, raise soil water deficits, and accelerate risks of forest fire.

But these results (declining relative humidity with declining temperature) just puts us down the road of a runaway ice planet or a runaway greenhouse.

To be fair, the models do produce results which show subtle changes in relative humidity at different layers and latitudes depending on temperature changes.

The view is based on results of simplified models of the troposphere that advect water passively and contain virtually no microphysics other than the requirement that water vapor is immediately removed so as to prevent the relative humidity (RH) from exceeding 100 %.

As a result, it would become «drier» (i.e., relative humidity would decline) as well as warmer.

So as it descends its relative humidity drops — and in the sub-tropics this can result in relative humidity less than 10 %.

m day and night 24/365 for the flat earth assumed by Trenberth & Kiehl, above which there is an apparently stationary sun), relative humidity, water vapour (H2O), windspeed, etc., plus the all - in Net anthro Forcing of GISS that I used in my last (it does not help your cause if you had actually read my results).

As in Fig. 6, we also include the linear least squares fit, model results, and extremes of constant specific and relative humidities.
