利用大洋渔船在智利外海观测的风场资料与QuikSCAT 10m散射风原始轨道资料L3产品进行了比较分析。两种资料的偏差统计特征显示:①智利外海船测风速总体上高于QuikSCAT风速,船测风向总体上偏于QuikSCAT风向的左侧;②智利外海船测风场资料与QuikSCAT散射风的风速偏差集中分布在-1～1m/s之间;风向偏差主要集中分布于-60°～-10°之间,其次为10°～60°和-10°～10°段;③智利外海白天的风速偏差特征值均小于夜晚,昼、夜风向平均偏差数值差别很大,但昼、夜风向平均绝对偏差、均方根偏差数值相差不大;④2008年智利外海船测风场资料与QuikSCAT散射风的偏差大于其他年份的整体平均值,在高风速段风速偏差尤为明显。
The wind field data of oceanic fishing vessels observed in the open sea of Chile and the QuikSCAT 10m scattering wind original orbit data L3 products were compared and analyzed. The statistical characteristics of the deviations of the two data show that: ① The measured wind speed of the Chilean offshore seagoing ships is generally higher than that of the QuikSCAT wind direction, and the wind direction measured is generally biased to the left of the QuikSCAT wind direction; ② The wind speed deviation between the data of the wind farms and the QuikSCAT scattered winds The wind direction deviations are mainly concentrated in the range of -60 ° -10 °, followed by the ranges of 10 ° -60 ° and -10 ° -10 °. ③ The wind speed of the Chilean offshore during the daytime The deviations of eigenvalues are less than those of the night, the values of average deviation of day and night wind are quite different, but the average absolute deviation of day and night wind direction, the difference of rms deviation is not big; Deviations greater than the overall average of other years, especially in high wind speed wind speed deviation is particularly evident.
