【摘要】 以2010~2015年的岸基雷达海冰监测数据为基础,简要分析了鲅鱼圈海域的冰期、冰型和冰厚等冰情基本特征。近年来的海冰监测数据表明,鲅鱼圈海域的冰期明显偏短,冰期内不同阶段的冰型变化较明显,鲅鱼圈海域部分时段海冰分布比例变化较大,这主要归因于该区域的海冰运动。针对目前岸基雷达海冰监测的技术发展现状,提出了岸基雷达海冰监测技术研发的主要问题是雷达像元回波值不稳定与海冰实测样本量匮乏。更多还原

【Abstract】 Based on the sea ice data of shore-based radar from 2010 to 2015, this paper comes up with a brief analysis on the basic characteristics of ice period, ice type and ice thickness of Bayuquan area. The recent monitoring data indicate that the ice period shortened, the ice type changed obviously in different phases of the ice period, the variation of sea ice area is large due to the movement of the sea ice. According to the status of shore-based radar monitoring technology on sea ice, this paper puts forward some problems for further study such as the instability of radar pixel and the deficiency of the first-hand sea ice data.更多还原
