Sentences with phrase «water vapor content on»

These issues, which are either not recognized at all in the assessments or are understated, include: - the identification of a warm bias in nighttime minimum temperatures - poor siting of the instrumentation to measure temperatures - the influence of trends in surface air water vapor content on temperature trends - the quantification of uncertainties in the homogenization of surface temperature data, and the influence of land use / land cover change on surface temperature trends.

Not exact matches

But on a plane, the low water vapor content and air pressure combined with more rapid breathing equals a need for more water.
Most climatologists expect that on average the atmospheres water vapor content will increase in response to surface warming caused by the long - lived greenhouse gases, further accelerating the overall warming trend.
Alternatively, more direct observations of that radiative imbalance would be nice, or better theoretical and observational understanding of the water vapor and cloud feedbacks, or more paleoclimate data which can give us constraints on historical feedbacks, but my guess is that ocean heat content measurements would be the best near term bet for improving our understanding of this issue.
Rearranaging the winds and water vapor distribution strikes me as a good candidate for effecting a flip on the time scale of a few years, with water vapor content resetting the thermostat.
Ray, let's plot the distribution on the vertical axis for some metric related to RP's water vapor content (isn't there something called «hurricane energy» or the like?)
The second nonlinearity is that the water vapor feedback depends on the moisture content of the air, which via the Clausius - Clapeyron relation is a nonlinear function of temperature.
Climate projections, such as those used by the Intergovernmental Panel on Climate Change, rely on models that simulate physical properties that affect climate, including clouds and water vapor content.
Water vapor on the other hand is a much more potent climate driver since there is a much larger content with a large variation, from under one percent (10,000 ppm) to close to 10 percent (100,000 ppm).
To name one relevent initial condition that has changed......... atmospheric water vapor content has changed on every spatial level.
States that other feedbacks likely to emerge are those in which key processes include surface fluxes of trace gases, changes in the distribution of vegetation, changes in surface soil moisture, changes in atmospheric water vapor arising from higher temperatures and greater areas of open ocean, impacts of Arctic freshwater fluxes on the meridional overturning circulation of the ocean, and changes in Arctic clouds resulting from changes in water vapor content

Elliott et al. conclude, based on the selected data below 500 hPa only that SH (moisture content) increased slightly with warming, but not at a rate sufficiently strong to maintain constant RH, as is assumed by the IPCC models in estimating water vapor feedback.
1) The Perry curves in this posting are based on NASA measurements taken in the Arctic, where the water vapor content of the Atmosphere is less than in regions closer to the Tropics.
Wild et al. (2001) proposed that 344 W m − 2 is a best estimate from models but noted that considerable uncertainties exist and especially that there were problems in accurate simulation of thermal emission from a cold, dry, cloud - free atmosphere, and a dependence on water vapor content.
