in this study, a new array of meteorological elements and a synoptic climatologic classification to produce abaseline climate and to derive meteorological factors that are effective on air pollution in tehran, which is located in a semi-enclosed basin was developed. the data set includes daily sea-level pressure and 500mb geopotential height fields from ncep-ncar and tehran upper air sounding d...

This work aims at analyzing and architecting natural artificial parameters to model a water-film cooling system for photovoltaic modules some months under warm conditions. Methodologically, the theoretical technical aspects were structured develop, implement, monitor, assess an on-grid, outdoor testing unit, considering following: (i) criteria select approve implementation site (infrastructure ...

Albedo is a key component of the atmospheric, climatologic and remote sensing studies by means global warming, energy balance, evapotranspiration, climate models, hydrological cycle etc. For these reasons, accurate determination surface albedo has become more important. In this study, variation measured values winter wheat, barley sunflower cultivars according to phenological stages was investi...

in this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. and generalize weakly zamfirescu map in to modified weakly zamfirescu map.

Abstract The ocean mixed layer temperature equation is used to estimate the surface net heat flux from drifter measurements. determined for both climatologic and tropical cyclone (TC) conditions. spatial distributions of drifter-derived fluxes under two conditions are similar those derived satellite observations. However, appears be weaker in magnitude than that satellites, performs better clos...
