Wind potential for clear energy production in most of Iran regions is very high. In this paper a statistical analysis on wind data of Jangal station in Khorasan Razavi province is implemented. Renewable energy organization of Iran’s 12-monthed data are used for wind energy calculations. Wind velocity at 40, 30 and 10 meter heights is studied firstly. Mean wind velocity on this section at mentioned height is 4.78, 4.52, 3.76 m/s respectively. Also windrose of wind blow direction is investigated. Using windrose graph, wind velocity and direction at 30 and 37.5 meters height is presented. Dominant wind direction is between north and northwest for 30m height and is between west and northwest for 37.5m height. According to Jangal station wind rose dominant wind direction is fixed. It's important in turbines arrangement, because wind direction fixing is an important advantage for a wind power station. Annual wind mean power at 10, 30 and 40 meters height show that maximum of wind power production is on February. Also with evaluation the annual wind average power at heights of 10, 30 and 40 meters can be seen 40 and 30 meters heights for installing wind turbines are suitable.
