| 利用黄河口区域孤东59井验潮站、桩西106验潮站资料和CCMP、CFSR、ERA-interim、JRA-55四种再分析资料,对比研究了再分析资料近地面10m平均风场在黄河口区域的适用性问题。结果表明CCMP风场最能反映黄河三角洲海域海上风场特征。CCMP数据的平均相对误差、均方根误差最小,与实测数据的相关系数最大,且夏冬季相关系数相差不大。在强风过程下,CCMP风场最能表达黄河三角洲海域海上风场特征,其中冬季拟合程度比夏季好。1988-2018年黄河三角洲海上风场多年平均风速为5.33m/s,1988-2009年,冬、夏季及全年风速均呈上升趋势,而自2010年后,夏季上升速度加快,冬季风速呈降低趋势,年平均风速主要由冬季控制而呈现下降趋势。 |

| Abstract: |
| Based on the data of well Gudong 59 and Zhuangxi 106 and the reanalysis data of CCMP, CFSR, era interim and jra-55, the applicability of the reanalysis data in the Yellow River estuary is studied. The results show that CCMP wind field can best reflect the characteristics of offshore wind field in the Yellow River Delta. The average relative error and root mean square error of CCMP data are the smallest, and the correlation coefficient between CCMP data and measured data is the largest, and there is no significant difference in summer and winter. In the strong wind process, CCMP wind field can best express the characteristics of offshore wind field in the Yellow River Delta, and the fitting degree in winter is better than that in summer. From 1988 to 2018, the average annual wind speed of the Yellow River Delta offshore wind field was 5.33m/s. From 1988 to 2009, the wind speed in winter, summer and the whole year showed an upward trend. Since 2010, the rising speed in summer has accelerated, and the winter wind speed has shown a downward trend. The annual average wind speed is mainly controlled by winter and presents a downward trend. |
