prediction of climatic variables on a local scale by general circulation models of the atmosphere is impossible because the models have large-scale network of resolution. therefore, downscaling methods are used to solve this problem. since the climate change phenomenon can affect different systems such as, water resources, agriculture, environment, industry and economy as well, selection of the...
The purpose of this research was to investigate the trend of annual changes in Yazd stationchr('39')s meteorological parameters including minimum and maximum average daily temperature and average daily precipitation (1961-2005), as well as the predicted annual mean of these parameters in the three upcoming thirty years of the 2040s, 2070s and 2100s, by the SDSM model, under RCP2.6, RCP4.5, RCP8...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
Climate change has a critical impact on water resources, especially in arid regions. In the first part of the study, the LARS-WG was used for downscaling of climatic variables including rainfall, solar radiation, minimum and maximum temperature over the Ghareh-Chay basin in Markazi province for a 31 year historical period (1983-2013). Results showed that LARS-WG can be applied successfully to d...
A method was developed for scaling-up the AFRCWHEAT2 model of phenological development from the site to the continental scale. Four issues were addressed in this methodology: (i) the estimation of daily climatic data from monthly values, (ii) the estimation of spatially variable sowing dates, (iii) the simulation of multiple cultivars, and (iv) the validation of broad-scale models. Three method...
increasing greenhouse gases in recent decades and increasing its resulting temperature has causes the imbalance of the earth’s climate system and widespread climate changes in most regions of earth planet. development strategic policy in this area has been forced with a big challenge because of the need for water in the central region on the one hand and water resource constraints on the other ...
