Assessment of drought condition in the Sistan and Baluchestan province during (2012- 2031) using Downscaling the data of Atmospheric General Circulation model

In recent decades، the increase of weather data has caused the disturbance of climatic balance of the earth which is called climate change. The aim of this study، is to predict climatic changes of Sistan-va Baluchestan province using statistical downscaling in which A2 scenario of ECHO-G atmospheric general circulation model is performed. Which were downscaled in order to evaluate climatic، drought، and glacial changes in the statistical period of 2012 - 2031 using LARS-WG model In this study، the data of minimum temperature، maximum temperature، radiation، and precipitation of ECHO-G model، and real data of seven stations of the province including Chabahar، Iranshahr، Khash، Saravan، Zabol،Zahak and Zahedan were used. Overall results of surveys shows 8 percent increase of precipitation in the province and a decrease of glacial days and the increase of average annual temperature by about 0. 3 centigrade، and the highest temperature increase will belong to the winter season by about 0. 9.
