本研究利用WRF和WW3进行风浪数值模拟，并利用实测资料验证预报的风速、波高和波周期。风速、波高和波周期的月绝对误差年平均值分别为4.30%、12.3%和7.8%。在低波高和短波周期区域，通过偏差修正，提高了预报精度。预测的季节性频率分布与测量结果吻合良好。在铫子和北九州风电场调查了经验施工方法的标准，并阐明了环境条件对天气停机的敏感性。在铫子，天气停机时间是通过使用风和波浪模拟来预测的，并且与实际天气停机时间吻合良好。
In this study, numerical simulations for winds and waves were carried out using WRF and WW3 and the predicted wind speed, wave height and wave period were validated with measurement. Annual average values of absolute monthly error of wind speed, wave height and wave period were 4.30%, 12.3% and 7.8%. The prediction accuracy were improved by bias modification in the region of low wave height and short wave period. Predicted seasonal frequency distributions showed good agreement with measurements. The criteria of experienced construction methods were investigated at Choshi and Kitakyushu wind farm and the sensitivity of environmental conditions on weather downtime were clarified. At Choshi, the weather downtime was predicted by using wind and wave simulations and showed good agreement with the actual weather downtime.
