the fact that water is the most important factor of life on earth is not a new concept. alteration and reduction in the amount of precipitation, population explosion and contamination of underground water pressurize governments severely to find solution for water resources. the air moisture is one of fresh water resources which has not been noticed and well exploited. in this study proper place...

[1] Key climate feedback due to water vapor and clouds rest largely on how relative humidity R changes in a warmer climate, yet this has not been extensively analyzed in models. General circulation models (GCMs) from the CMIP3 archive and several higher‐ resolution atmospheric GCMs examined here generally predict a characteristic pattern of R trend with global temperature that has been reported...

Water is a nearly miraculous molecule that enters into the operation of the climate system in a remarkable variety of ways. A wide-ranging overview can be found in Pierrehumbert (2002). In the present chapter, we will be concerned only with the radia-tive effects of atmospheric water vapor on climate, and with the kinematics of how the water vapor distribution is maintained. These effects are i...

realistic prediction of concrete shrinkage and creep requires the calculation of the distributions of relative humidity at various times. although the distributions of the relative humidity can be computed by numerical methods from the differential equation for diffusion, simple prediction formulas can facilitate structural analysis. the purpose of this paper is to present a simple formula for ...

The sensitivity of free-tropospheric relative humidity to cloud microphysics and dynamics is explored using a simple 2-D humidity model and various configurations of the NCAR CAM3 Atmospheric General Circulation Model (AGCM). In one configuration the imposed surface temperatures and radiative perturbations effectively eliminated the Hadley and Walker circulations and the main westerly jet, crea...

Climate change is a global concern, requiring local scale spatially continuous dataset and modeling of meteorological variables. This dataset article provided the interpolated temperature, rainfall and relative humidity dataset at local scale along Taita Hills and Mount Kilimanjaro altitudinal gradients in Kenya and Tanzania, respectively. The temperature and relative humidity were recorded hou...
