用于识别连贯海洋涡旋的方法可分为欧拉方法和拉格朗日方法两类。在拉格朗日结构中，黑洞涡旋展现出最高程度的物质连贯性与守恒性，使其特别适用于海洋物质输送与滞留的研究。通过高效的基于图形处理单元（GPU）的黑洞涡识别与追踪算法，首次基于卫星衍生的地转表面流速数据（覆盖1993年1月1日至2023年5月5日），构建了首个北太平洋黑洞涡数据集。该数据集不仅包含寿命为T=30天和90天的涡旋基本特征（涡旋中心位置、等效半径、涡旋面积等），更完整记录了黑洞涡旋整个生命周期的轨迹。本研究填补了海洋学领域黑洞涡旋数据集的空白，为致力于解析协同涡旋与海洋物理现象相互作用的海洋学家提供了新的研究视角。", "ds_source": "

The methodologies employed for the identification of coherent ocean eddies can be categorized as either Eulerian or Lagrangian. Among Lagrangian structures, Black Hole Eddies exhibit the highest degree of material coherence and conservation, making them particularly suitable for studies on the transport and retention of oceanic materials. Using an efficient Graphics Processing Unit (GPU)-based Black Hole Eddy identification and tracking algorithm, the first North Pacific Black Hole Eddy dataset was constructed for the first time based on satellite-derived surface geostrophic velocity data spanning January 1, 1993 to May 5, 2023. This dataset contains not only the general features (eddy center position, equivalent radius, eddy area, etc.) of eddies with lifetimes of T=30-day and 90-day but also the trajectories of Black Hole Eddy over the lifetime. This research addresses the existing gap in Black Hole Eddy datasets within the field of oceanography and offers additional insights for oceanographers who seek to comprehend the interactions between coherent eddies and oceanic physical phenomena.
