江苏沿海地区的风能资源模拟的时空分布

摘要

通过选取最优的WRF参数化方案组合，对各季代表月进行江苏沿海地区的风能资源数值模拟，验证模拟结果的可信度。模拟结果为风速分布变化受海陆差异影响较大，受热不均，沿海风速梯度变化明显且较密集，江苏地区风能资源相对丰富。风速随高度的增大而增大，且最高层受海陆分布差异影响最小，风场的季节性特征明显。最终对比结果表明：WRF模式较好地体现风速变化规律，为江苏沿海地区风能资源开发利用提供科学依据。%By integrating the optimal WRF (Weather Research and Forecasting Model ) parameterization schemes ,the wind energy resources in Jiangsu coastal area are simulated in the typical months. The simulation shows that there exist abundant wind energy resources in Jiangsu. Since wind speed distribution varies by the surface type and uneven heating ,also there is large gradient in coastal areas. Wind speed increases with height and the top layer is affected lest by the distribution of land and sea. Besides ,the wind fields have evident seasonal characteristics. The results re-flected that :the wind speed variation significantly through WRF simulation and provide the scientific basis for exploring the wind energy resources at Jiangsu coastal area .
