It is rewarding to understand the actuality of wind resources to increase utilization ratio because the using of wind resources plays an important role in developing of offshore resources in Jin-Jing-Ji region. It is significative for effective resources utilization to promote the progress of region economy, environment protection, tourism and local eco-development. There are abundant wind resources in Caofeidian region which is typical as the wind region according to the weather statistic year by year. The wind energy density is above 140W/m2. The total of the hours is between 4800 and 5600 when the wind speed is above 3m/s.The wind resources of the Caofeidian wind field were analyzed and appraised according to the testing weather parameter from weather station of Caofeidian, the tower of the winds and neighboring two weather stations. The mean wind speed, mean wind power density, hours of wind speed, the annual and representative daily variation of wind speed and wind power density were analysised. The wind direction rose map and wind energy rose from Jul. 2007 to Jun. 2008 in wind farm of Caofeidian were made. The 10min maximal wind speed was calculated at 10m high hub. The wind power density reaches Grade 2 on GB/T18710-2002 for a wind power plant, which belongs to IECIIIC. The wind resources are relatively abundant in Caofeidian. These study results on the wind direction and power can be used as a reference for the city planning and building community distributing in Jin-Jing-Ji region. © 2011 Published by Elsevier Ltd.
