中文摘要：我国自主研发的HY-2系列动力卫星为全球海洋风场观测研究提供了重要的数据支撑。通过对多源遥感卫星所获取的海面风场数据进行融合,形成高时空分辨率的风场融合数据,对研究台风灾害、保障船舶航行和海上作业安全具有重要意义。对风场融合数据进行交叉验证是该数据大规模应用的前提,本文选择台风灾害频发,渔业资源丰富的西北太平洋海域作为研究区域,利用ERA5再分析数据、CCMP风场数据及CERSAT风场数据作为参考数据,通过获取不同数据集之间的风速、风向的标准差和相关系数,开展了2019年12月至2021年11月HY-2系列卫星风场融合数据在不同季节间的交叉验证分析。结果表明:(1)HY-2系列卫星风场融合数据与ERA5再分析数据的匹配程度优于CCMP风场数据和CERSAT风场数据;(2)在不同季节中,HY-2系列卫星风场融合数据的风速和风向精度在夏季和秋季较高,而冬季和春季相对较低;(3)2019年12月至2021年11月的HY-2系列卫星风场融合数据的风速和风向具有较高的精度,其标准差分别为1.54 m/s和13.29°,相关系数分别为0.92和0.88,可广泛应用于西北太平洋海域。

外文摘要：China's independently developed HY-2 series of power satellites provide important data support for global ocean wind field observation and research.By fusing the sea surface wind field data acquired by multi-source remote sensing satellites to form wind field fusion data with high temporal and spatial resolution,it is of great significance to the study of typhoon disasters and the safeguarding of the safety of ship navigation and offshore operations.Cross-validation of wind field fusion data is a prerequisite for the large-scale application of this data.In this paper,the Northwest Pacific Ocean,which is prone to typhoon disasters and rich in fishery resources,is selected as the study area,and ERA5 reanalysis data,CCMP wind field data and CERSAT wind field data are utilized as the reference data.By obtaining the standard deviation and correlation coefficients of wind speed and direction between different datasets,the cross-validation analysis of HY-2 series satellite wind field fusion data between different seasons from December 2019 to November 2021 was carried out.The results show that:①the HY-2 series satellite wind field fusion data match the ERA5 reanalysis data better than the CCMP wind field data and CERSAT wind field data.②In different seasons,the wind speed and direction accuracy of the HY-2 series satellite wind field fusion data is higher in summer and fall,and relatively lower in winter and spring.③The wind speed and wind direction of the HY-2 series satellite wind field fusion data from December 2019 to November 2021 have high accuracy,with standard deviations of 1.54 m/s and 13.29°,and correlation coefficients of 0.92 and 0.88,respectively,and can be widely used in the Northwest Pacific Ocean.
