摘　　要：利用中尺度MM5气象模式系统,对大连及其近海地区风场进行了较为系统的高分辨率数值模拟,定性及定量地得到了该地区10 m高度处的年平均风速等直线图、年有效风能小时数等值线图、年有效风能功率等值线图及长海地区的年风玫瑰图,进一步研究了该地区年有效风能功率密度沿垂直高度的变化。综合考虑该地区沿海水深、港口运输及水产养殖等因素的影响,建设性地提出了3个近海风能重点开发区域,并给出了这3个地区的年风速分布概率情况。基于MM5模式的数值评估结果,为该地区近海风资源的开发利用提供了重要的参考依据。The sophisticated non-hydrostatic high-resolution numerical simulation of wind Mesoscale meteorology MM5 Model has been applied to fields in Dalian coastal zone. The annual average wind speed contour map, the annual available wind hourly contour map, the available wind energy density contour map and the wind rose map have been qualitatively and quantitatively obtained for Dalian. Fur- thermore, the effect of the different vertical heights on the wind energy power density has been studied. Taking the factors of water depth, port transportation and aquafarm into consideration, three key wind energy exploitation zones are proposed and the wind speed distribution probabilities for these places are given. In general, the high-resolution numerical results from MM5 model may effectively provide an important scientific basis for the exploitation of the offshore wind energy in Dalian.
