利用中尺度大气模式MM5对大连地区的风场进行了空间分辨率为3公里的数值模拟。研究中使用了美国国家环境预报中心的1°×1°再分析资料，计算周期覆盖了整个2000年。通过与3个气象站的现场观测资料进行对比，对模式进行了验证。对输出的资料进行了进一步的处理，并绘制了年平均风速等值线图。对大连地区海上风能资源的分布进行了分析，测试结果表明大连地区海上风能资源丰富，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.
