| Zusammenfassung |
| We use a recently developed Lagrangian transport tool, Lagrangian
descriptors, to compare the transport properties of data distributed by
AVISO and numerical simulations obtained from the HYCOM model in the
Yucatán–Florida current system. Our data correspond to the months from June
through August 2010. Structures obtained from HYCOM are noisier than those
from AVISO; however, both AVISO and HYCOM succeed in identifying Lagrangian
structures that influence the paths of drifters, such as eddies, currents,
lobes, etc. We find evidence in which AVISO gives the positions of important
hyperbolic trajectories in a manner that is inconsistent with the
trajectories of the drifters, while for the same examples HYCOM succeeds to
this end. |
