1. Introduction: Most of the warming over the last 50 years has been caused by emissions of carbon dioxide (CO2) and other greenhouse gases due to human activities. Observed changes in the climate due to increasing greenhouse-gas concentrations have made it essential to investigate these changes. The General Circulation Model (GCM) is the most current method of investigating climate change studies. Although they are imperfect and uncertain, these models are a key to understanding climate change.However, it still has serious difficulties in reproducing daily precipitation and temperature despite an increasing ability of GCMs to successfully model the presentday climate. Even when daily GCMs output is available, the coarse spatial resolution of GCMs and large uncertainty in their output on a daily scale, particularly for precipitation, indicates that the output is not appropriate for direct use with processbased models and the analysis of extreme events. Output of GCMs requires application of various downscaling techniques. One of the downscaling techniques to create daily site-specific climate scenarios is to makes use of a stochastic weather generator.Recently, weather generators have been used in climate change studies to produce daily site-specific scenarios of future climate...
