摘　　要： 利用中尺度气象模式WRF,对湖北省的风能资源状况做高空间分辨率的数值模拟试验,结果表明,模式模拟结果基本能够反映风能资源的分布情况。模拟发现,鄂东北地区大别山沿线、鄂州的梁子湖和江汉平原的洪湖等特殊地貌地区的年平均风速相对较大,可以考虑在上述地区寻找风能资源较丰富的观测点开展加密观测,为湖北省大范围开展风能资源评估和风电场选址提供参考依据。模式模拟的风的季节性变化结果与实际吻合度较高,但具体到地理分布吻合程度偏低,需要进一步优化模式并收集更多的个例进行模拟试验。 The numerical simulation experiment with high spatial resolution for the wind energy resources distributions in Hubei province is conducted with mesoscale meteorological model WRF. The results indicate the simulation can represent the distribution characteristics of wind energy resources. Also, simulating results show that there are bigger mean annual wind velocity in some areas with special topography such as the region along with Dabie mountains ridge in the north-eastern Hubei, Liangzi Lake in Ezhou city and the Hong Lake in Jianghan Plain. So it should be considered to establish several observation spots in the above areas and carry out intense wind speed measurement for supporting assessment of wind energy resources and location decision of wind-power plants throughout Hubei. In addition, the simulation for seasonal variation of wind velocity is more fitting to real data than that for terrain distribution of wind velocity. It suggests that the numerical model should be made further progress and more cases for wind energy evaluation.
