Abstract

Increasing the Earth’s temperature causes disrupting climate balance of the Earth and causes wide climate changes in most areas of the Earth which is defined as “climate change”. Using statistical microscale models in estimation of climate fluctuations makes it possible to produce weather data in proper spatial-temporal scale. Efficiency of LARS - WG Model was studied and evaluated through using statistical parameters RMSE, R2, MAE and MBE for producing and simulating of daily data of minimum and maximum temperature, precipitation and radiation in Borujerd and its resulted changes in the future decades became clear. The results represented that the model is capable enough to produce daily data and used the model’s output after being sure regarding model efficiency and daily data of minimum and maximum temperature, precipitation and radiation for base period (1996 – 2015) was simulated under three scenarios A1B, A2, B1. Results which are obtained from estimation of HadCM3 Model for case studies in the future periods, the average of total meteorology parameters have had increasing trend and each of these three scenarios represent this amount of increase.
