Particle trajectories and simple models of transport in coherent vortices

摘要: Abstract The particle trajectories and transport effects of coherent vortices are computed a number advection diffusion experiments using time-dependent dynamical ring model analyzed. Several features the tracer distributions in numerical solutions similar to noted sea surface temperature images Gulf Stream rings discussed from point view model. Comparisons between dynamic several purely kinematic representations demonstrate that most important not altered by slow evolution. Loss rates trapped zone also estimated, which permits calculation cross-Gulf chemical biological fluxes due formation.
