在概述风资源评估传统方法的基础上，通过以下两个方面对基于WRF模式的海上风资源评估方法进行探讨。首先，详细分析了基于WRF模式的海上风资源评估的过程；其次使用珠江口某设计中的海上风场作为算例，进行了风资源量化估计，并对结果进行了对比。得出的主要结论为，鉴于我国缺乏长期和大面积的海上测风网，使用数值天气预报对海上风资源进行评估是必须的；风切变指数的变化剧烈，不应视作常数；数值预报数据应根据测风塔数据进行校正；对于选定了位置的风场，根据现场测风塔和根据数值天气预报给出的评估结果无显著差别。

Traditional wind resource assessment methods were summarized. The WRF model based offshore wind resource assessment method was discussed from two aspects. First, marine wind resource assessment based on WRF model was analyzed in detail;secondly, the wind resource was quantitatively estimated with examples of Pearl River offshore wind farms, and the results were compared. It was concluded that use of numerical weather prediction for offshore wind resource assessment is necessary for lack of long-term and large-scale offshore wind measurement network;wind shear exponent changes dramatically and should not be treated as a constant; NWP data should be corrected based on the data of anemometer tower; for wind farms with designated location, there is no significant difference between assessment of anemometer tower and NWP.
