使用拉格朗日粒子跟踪软件和海洋环流和气候估计第二阶段(ECCO2)项目输出的允许涡流的海洋模型输出来模拟浮标轨迹。我们发现,在强平均流附近,类ARGO粒子在其停车深度时倾向于加速。这一影响在西部边界流区和南极绕极洋流系统中表现明显。加速与涡流-平均流相互作用有关:涡流将粒子汇聚到平均流较强的区域。当粒子单独受到涡流或平均流的平流时,它们不会加速。在9天的停车期内,涡流-平均流相互作用导致的车速增加可达S−1的2厘米,约占平均车速的10%。如果找不到原因,这种加速度可能会偏离从观测到的Argo漂浮轨迹推断的速度。
Float trajectories are simulated using Lagrangian particle tracking software and eddy‐permitting ocean model output from the Estimating the Circulation and Climate of the Ocean, Phase II (ECCO2) project. We find that Argo‐like particles near strong mean flows tend to accelerate while at their parking depth. This effect is pronounced in western boundary current regions and in the Antarctic Circumpolar Current system. The acceleration is associated with eddy‐mean flow interactions: Eddies converge particles toward regions with stronger mean currents. Particles do not accelerate when they are advected by the eddy or mean flow alone. During a 9‐day parking period, speed increases induced by the eddy‐mean flow interactions can be as large as 2 cm s−1, representing roughly 10% of the mean velocity. If unaccounted for, this acceleration could bias velocities inferred from observed Argo float trajectories.
