In the current research, wind energy potential at Kerman synoptic stations which contain wind data with 20 years statistic period and beyond, including Kerman synoptic station (30°.15ʹN, 56°.58ʹE, 1753.8 M high), 1951-2011; Kahnooj (27.58ʹN, 57°.42ʹE, 469.7 M high), 1989-2011; Bam (29°.06ʹN, 58°.21ʹE, 1066.9 M high), 1956-2011; Baft (29°.14ʹN, 56°.35ʹE, 2280 M high), 1986-2011; Anar (30.53ʹN, 55°.15ʹE, 1408.8 M high), 1986-2011; Shahrbabak (30°.06ʹN, 55°.08ʹE, 1834.1 M high), 1987-2011; Sirjan (29°.28ʹN, 55°.41ʹE, 1739.4 M high), 1985-2011; Miandeh- Jiroft (28°.35ʹN, 57°.48ʹE, 601 M high), 1989-2011 and Rafsanjan (30°.25ʹN, 55.54ʹE, 1580.9 M high), 1992-2011 has been studied. Wind data were obtained from the recorded data at Tehran meteorology organization. This data was recorded at an interval of 3 h at 10 m height above the ground level. Using weibull distribution function, discontinuous wind data were substituted. This substitution has been applied through least square feet after computing weibull parameters C & K. Wind date were changed at 10 m height to 50 m by applying one seventh power law (50 m is the most height of turbines axis) and characteristics of both wind speed and wind power in each height has been computed. Due to wind power density equals 292.63 and 583.29 w/m2 at 10 and 50 m height respectively, average wind speed equals 17.42 m/s at 50 m height, wind existence equals 7438.5 h/y, probability of wind blowing in the wind existence hours with speeds between 3 to 25 m/s equals 0.95, most probability of wind speed equals 7.77 m/s, the result show that Rafsanjan synoptic station is an ideal place having high wind energy potential. Application of wind energy at this synoptic station with automatic turbines working at the speed of 3 m/s at 50 m height axis and above has been economically efficient.
