摘　　要：利用MM5中尺度气象模式和美国国家环境预报中心提供的1°×1°再分析初始场资料,对大连近海地区的风场进行了网格距为3km的高空间分辨率数值模拟,模拟时段为2000年全年.通过对比3个气象站风速的数值结果与站点观测结果,验证了该模式的有效性.对MM5模式的输出结果进行了后处理,得到了大连近海地区的年平均风速、年平均功率密度和年可利用时间等评估参数的等值线图,对大连市近海风能资源分布情况进行了分析.结果表明,大连近海地区风能资源较为丰富,具有较大的开发价值.The wind field in Dalian area is simulated at a high spacial resolution of 3 km by using meso-scale atmospheric model MM5.The 1°×1° reanalytical data which is from National Centers for Environmental Prediction of America is used in this study and the computational period covers the whole year 2000.The model is validated by comparing the numerical results with the field observed data from three meteorological stations.The output data are further processed and the contour maps of yearly average wind speed,yearly power density and yearly effective hours are obtained.The distribution of offshore wind energy resources in Dalian area is analyzed.The test results show that the offshore wind energy resource in Dalian area is rich and has great value for development.
