Based on observational data at 70 m height from 19 wind towers from Jun 1,2009 to May 31,2010 in Shandong coastal areas,the reserves and distribution characteristics of wind speed and wind energy at 70 m height were analyzed using statistical methods.The results show that the distribution characteristics of the average wind speed are accordant with effective wind power density in Shandong coastal areas.The average wind speed and effective wind power density are up to 6.7 m/s and 463.5 W/m²,respectively in Yantai coastal area.The wind energy resources are much richer in the north area than in other areas,with the poorest being in Rizhao area.Due to the influence of sea breeze,the wind energy resources are richest in spring,followed by winter,and poorest in summer,and the maximum of the daily wind speed appears in period of 14:00-16:00.Results also show that the mean annual effective hours of wind and its percentage are 7 440 h and 85%,respectively.The distribution of wind energy density is larger in the northerly or southerly azimuth.The distribution characteristics of wind speed and wind energy are generally consistent with the results of long time evaluation and numerical simulation.
