Temporal-spatial distribution of the wind energy in Liaoning littoral
辽宁沿海地区风能资源时空分布的初步分析

The characteristics of wind energy along Liaoning coastal area were extracted from the wind data from 1997 to 2008 with the method of inverse distance weighted interpolation. The results show that the Liaodong Bay coastal area is rich in wind energy, which reaches 250 W/m2 per year. The wind energy in the south and southeast of Dalian coastal area reaches 175 W/m2 per year. Dandong and the northeast of Dalian coastal area is only a potential area for wind energy utilization, with a wind energy of about 75 W/m2 per year. In addition, the resources in the Liaoning coastal area in spring are relatively high, which is about 1.2 times of that in autumn and in winter, and 2.1 times of that in summer. This research has practical value to the rational utilization of wind energy resources along Liaoning coastal area and the divison of ocean functional area.
