Precipitation and temperature changes in Zayandehroud basin by the use of GCM models
Abstract
Surveys show that rate of emission greenhouse gases has increased considerably in recent decades. Increasing these gases in earth‘s atmosphere leads to changes in climatic parameters of earth. By using variety of simulated models of meteorological variants in general frame of weather generators during recent decades, it is necessary to apply these changes in simulated series. In this study, using statistical down –scale for periods of 2011-2039 by using statistical model of LARSE-WG daily data of temperature rain and radiation and its results were considered on synoptic station of zayanderoud basin. Results show that changes in climatic parameters will be existed during survey period in the way that temperature mean among studied stations will increase between 1/7 centigrade and 2/9 centigrade and raining rate will be decreased.
