论文摘要
旨在模仿浮动海洋碎片的漂流者和层状\ emph {sargassum}的小斑块在北大西洋的四个地区追踪。尽管在每个站点都经历了相同的初始条件，但部署后，不同漂移器的轨道很快就会差异。我们使用最新的Maxey-riley理论来解释漂流者类型的聚类，用于将基于多ATATA的中尺度海流和重新分析中的风施加在基于多ATA的中尺度海流和风中。当表示为惯性时（考虑浮力和大小），而不是完全lagranganian（流体跟随）粒子时，空气接口处的物体的模拟轨迹会显着改善。对于碎片样的漂移器而言，模拟和观察到的轨迹之间的分离距离要小于\ emph {sargassum}类似的漂流剂，这表明相对于流体速度，其物理性能的其他考虑可能是有用的。我们的发现可以应用于模拟流动在海面的各种物体的运动和分布中的变异性。
Drifters designed to mimic floating marine debris and small patches of pelagic \emph{Sargassum} were satellite tracked in four regions across the North Atlantic. Though subjected to the same initial conditions at each site, the tracks of different drifters quickly diverged after deployment. We explain the clustering of drifter types using a recent Maxey-Riley theory for surface ocean inertial particle dynamics applied on multidata-based mesoscale ocean currents and winds from reanalysis. Simulated trajectories of objects at the air-sea interface are significantly improved when represented as inertial (accounting for buoyancy and size), rather than as perfectly Lagrangian (fluid following) particles. Separation distances between simulated and observed trajectories were substantially smaller for debris-like drifters than for \emph{Sargassum}-like drifters, suggesting that additional consideration of its physical properties relative to fluid velocities may be useful. Our findings can be applied to model variability in movements and distribution of diverse objects floating at the ocean surface.
