rangelands are one of the most vulnerable parts concerning the climatechanges‟ impacts. these impacts are even stronger in the arid and semi-arid areas whererangeland ecosystems are in critical conditions. therefore, it is crucial to figure out theactual dynamics of climate variations on the rangelands. the aim of this research was todetermine climate changes in khabr rangeland, kerman, iran. s...

since many time series are not normal, it is required to normalize data by transformation functions prior to any analysis and modeling. in this study, the next month rainfall of abadeh county station was predicted using the average monthly rainfall, minimum and maximum temperatures and minimum and maximum humidity as inputs of mlp network, both normally and raw, at period 1976 to 2013. after sc...

weather condition is one of the much effective factors in the principle of architecture and urbanization. so in this research long-term trend of effective climate elements in architecture of darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...

introductionclimate change has played an important role in all aspects of human life. therefore, climatepredictions in atmospheric general circulation models (gcm) will have particular importance.in this study, downscaling by a1b scenarios, ipcm4 and bcm2 of atmosphere generalcirculation models in lars-wg model are used for analysis of climate change impacts onmaximum and minimum temperature, s...

introduction the city population, in particular at the industrialized cities and centers of provinces, has increased dramatically in iran during recent decades. arak city as center of markazi province is among those industrialized cities which has experienced a fast increase in population. these changes in population numbers tend to increase consuming water resources as well as increasing in en...

climate is a complex system which is changing mainly due to the increase of greenhouse gases. because of the importance of climate change and the effects it can have on water resources, in recent years, this topic has been taken into consideration for different basins on earth. the objective of this study is to investigate the effects of climate change and forecasting meteorological variables o...
