基于再分析数据的印尼西加里曼丹海域风速研究

Research on wind speed in the West Kalimantan Sea Indonesia based on reanalysis data

基于西加里曼丹近岸码头项目工程获取的OWI再分析资料,对ECMWF细网格10 m风场产品在印尼西加里曼丹海域的再分析结果进行了对比分析。ECMWF细网格10 m风场产品与OWI风场再分析结果对比表明:目标点ECMWF再分析数据总体分布与OWI再分析数据量级相近,但极值相异,ECMWF数据更能描述实际季节变化情况。基于此,利用ECMWF产品对印尼西加里曼丹海域整体风况进行了评价,为海域内未来的勘察设计工作提供整体的判断依据。

This paper compares the ECMWF find-grid 10 m wind speed reanalysis data with the OWI reanalysis data received from a port project in west Kalimantan,Indonesia.The result of comparison between the ECMWF find-grid 10 m reanalysis product and the OWI has shown that the range is in a comparable level but the extreme values behave dissimilarly.The ECMWF data is in accordance with the real seasonal variations.The ECMWF wind field in the West Kalimantan Sea is analyzed,which provides a general judgment for the future survey and design works.
