RISLagrangian Data Assimilation in Multilayer Primitive Equation Ocean Models
Publisher: American Meteorological Society
Abstract: Because of the increases in the realism of OGCMs and in the coverage of Lagrangian datasets in most of the world's oceans, assimilation of Lagrangian data in OGCMs emerges as a natural avenue to improve ocean state forecast ...
Historical Drifter Data and Statistical Prediction of Particle Motion: A Case Study in the Central Adriatic Sea
Publisher: American Meteorological Society
Abstract: In this paper, a method to analyze historical surface drifter data is presented that is aimed at investigating particle evolution as a function of initial conditions. Maps of drifter concentration at different times are ...
Barrier Layers in the Tropical South Atlantic: Mean Dynamics and Submesoscale Effects
Publisher: American Meteorological Society
Abstract: arrier layers are generated when the surface mixed layer is shallower than the layer where temperature is well mixed, in geographical regions where salinity plays a key role in setting up upper-ocean density stratification. ...
Lagrangian Analysis and Predictability of Coastal and Ocean Dynamics 2000
Publisher: American Meteorological Society
Abstract: The first Lagrangian Analysis and Predictability of Coastal and Ocean Dynamics (LAPCOD) meeting took place in Ischia, Italy, 2?6 October 2000. The material presented at LAPCOD 2000 indicated both a maturing of Lagrangian-based ...
Transport Properties in the Adriatic Sea as Deduced from Drifter Data
Publisher: American Meteorological Society
Abstract: The surface transport properties in the Adriatic Sea, a semienclosed subbasin of the Mediterranean Sea, have been studied using a drifter dataset in the period December 1994?March 1996. Three main points have been addressed. ...
Oceanic Turbulence and Stochastic Models from Subsurface Lagrangian Data for the Northwest Atlantic Ocean
Publisher: American Meteorological Society
Abstract: The historical dataset provided by 700-m acoustically tracked floats is analyzed in different regions of the northwestern Atlantic Ocean. The goal is to characterize the main properties of the mesoscale turbulence and to ...
How Does Drifter Position Uncertainty Affect Ocean Dispersion Estimates?
Publisher: American Meteorological Society
Abstract: o develop methodologies to maximize the information content of Lagrangian data subject to position errors, synthetic trajectories produced by both a large-eddy simulation (LES) of an idealized submesoscale flow field and ...
On the Predictability of Lagrangian Trajectories in the Ocean
Publisher: American Meteorological Society
Abstract: The predictability of particle trajectories in oceanic flows is investigated in the context of a primitive equation, idealized, double-gyre ocean model. This study is motivated not only by the fact that this is an important ...
Improved Surface Velocity and Trajectory Estimates in the Gulf of Mexico from Blended Satellite Altimetry and Drifter Data
Publisher: American Meteorological Society
Abstract: his study investigates the results of blending altimetry-based surface currents in the Gulf of Mexico with available drifter observations. Here, subsets of trajectories obtained from the near-simultaneous deployment of ...
