涡旋中的浮游生物水华：生物学和流体动力学时间尺度的作用
Plankton blooms in vortices: The role of biological and hydrodynamic time scales
摘要：
我们研究了水动力中尺度结构的相互作用和浮游生物的生长在一个岛屿的尾流，其与沿海上升流的相互作用。我们的重点是一个机制出现的局部浮游生物水华的漩涡。利用模拟岛屿后方中尺度结构的运动流和海洋生态系统的简单三分量模型的耦合系统，我们表明，营养盐和浮游生物在岛屿附近的长停留时间和浮游生物在涡旋中的限制是局部浮游生物水华出现的关键因素
英文摘要：
We study the interplay of hydrodynamic mesoscale structures and the growth of plankton in the wake of an island, and its interaction with a coastal upwelling. Our focus is on a mechanism for the emergence of localized plankton blooms in vortices. Using a coupled system of a kinematic flow mimicking the mesoscale structures behind the island and a simple three component model for the marine ecosystem, we show that the long residence times of nutrients and plankton in the vicinity of the island and the confinement of plankton within vortices are key factors for the appearance of localized plankton blooms
