摘要:

中尺度涡在海洋中无处不在,其对海洋能量传输和物质运输发挥着关键作用,目前常见的中尺度涡观测方式主要有卫星遥感和浮标示踪两类,不同观测方式具备不同的观测角度及尺度,因此形成的中尺度信息标准不一、各有特点。该文基于不同来源的三套中尺度涡数据集,提出一种两次融合策略,生成了一套南海中尺度涡融合数据,并分析了2014—2018年南海中尺度涡中心空间分布情况。结果表明,融合数据有效地解决了单一观测方式获得的中尺度涡信息存在的过度识别、漏判、误判等问题,能更好地体现出南海区域中尺度涡空间分布广泛、气旋涡与反气旋涡显著局部聚集、气旋涡与反气旋涡分区明显等特点。南海中尺度涡融合数据可以为跟踪中尺度涡轨迹、推演中尺度涡三维结构、理解海洋中尺度现象及环流等研究提供可靠的数据支撑。

Abstract:

Mesoscale eddies are ubiquitous in the ocean and play a key role in the transport of oceanic energy and matter. Current observation methods for mesoscale eddies includesatellite remote sensing, buoy tracking, and research vessel surveys. Each of these methods offer sdistinct scales and perspectives, resulting in varying mesoscale information standards and characteristics.Based on three mesoscale eddy datasets obtained using different methods, this study proposes a two-stage fusion strategy to generatea fused mesoscale eddy dataset for the South China Sea. Moreover,it analyzes the spatial distribution of mesoscale eddy centers in the South China Sea from 2014 to 2018.Results reveal that the fused dataset effectively mitigates issues such as over identification, omission, and misidentification found in single-source observations. Additionally, the fused dataset accurately reflects the wide spread spatial distribution of mesoscale eddies in the South China Sea, the substantial local aggregation of cyclonic and anticyclonic eddies, and clear partitioning between cyclonic and anticyclonic eddies. Furthermore, the fused dataset for the South can offerreliable data support for studies related totrajectory tracking of mesoscale eddies, inferring their three-dimensional structures, and understanding mesoscale oceanic phenomena and circulation.

Key words: mesoscale eddies, the South China Sea, sea level anomaly, satellite remote sensing, buoy tracking
