Impulse exchange at the surface of the ocean and the fractal dimension of drifter trajectories
Impulse exchange surface of the ocean fractal dimension drifter trajectories
2009/11/12
An impulse-based model is developed to represent a coupling between turbulent flow in the atmosphere and turbulent flow in the ocean. In particular, it is argued that the atmosphere flowing horizontal...
Asymptotic Properties of Optimal Trajectories in Dynamic Programming
Asymptotic Properties of Optimal Trajectories Dynamic Programming
2011/2/25
We show in a dynamic programming framework that uniform convergence of the finite horizon values implies that asymptotically the average accumulated payoff is constant on optimal trajectories. We anal...
A statistical study of Weinmannia pollen trajectories across the Andes

2010/1/28
Recent airborne pollen records data from Northern Patagonia (San Carlos de Bariloche, Argentina, Lat. 41.1435° S, Long. 71.375° W, 800 m elevation) suggest that pollen transport takes place from the w...

The influence of dissipation on the quantum-classical correspondence: Stability of stochastic trajectories
dissipation quantum-classical correspondence Stability of stochastic trajectories
2014/9/24
The quantum-classical correspondence in the presence of dissipation is studied. The semiclassical expression for the linear response function of an anharmonic system is expressed in a series containin...
Trajectories and Speeds of Wind-Driven Currents Wear the Coast
Wind-Driven Currents Trajectories Speeds
2009/3/24
Detailed observation of drogue movements within 800 m of a straight shoreline indicates the primary current generated by local winds to be directed within a few degrees of parallel to the shore nearly...
During the period 1976–78, the movement of 14 Gulf Stream rings, including two anticyclonic and 12 cyclonic rings, was measured with satellite-tracked free-drifting buoys. The buoys in the cyclonic ri...
Gulf Stream Trajectories Measured with Free-Drifting Buoys
Gulf Stream Trajectories Free-Drifting Buoys
2009/2/10
During 1975–78, 35 free-drifting buoys measured surface currents in the Gulf Stream region. The buoy trajectories trace numerous paths of the Stream and show that the Stream is strongly influenced by ...
Stratospheric age of air computed with trajectories based on various 3D-Var and 4D-Var data sets
Stratospheric age trajectories 3D-Var 4D-Var
2009/1/23
The age of stratospheric air is computed with a trajectory model, using ECMWF ERA-40 3D-Var and operational 4D-Var winds. Analysis as well as forecast data are used. In the latter case successive fore...
Accuracy of analyzed temperatures, winds and trajectories in the Southern Hemisphere tropical and midlatitude stratosphere as compared to long-duration balloon flights
temperatures winds trajectories Southern Hemisphere tropical midlatitude stratosphere long-duration balloon flights
2009/1/21
Eight super-pressure balloons floating at constant level between 50 and 80 hPa and three Infra-Red Montgolfier balloons of variable altitude (15 hPa daytime, 40–80 hPa night time) have been launched a...
Potential Vorticity Balances and Horizontal Divergence along Particle Trajectories in Gulf Stream Meanders East of Cape Hatteras
Potential Vorticity Balances Horizontal Divergence Particle Trajectories Gulf Stream
2009/1/5
Trajectories of 37 isopycnal RAFOS floats launched in the Gulf Stream off Cape Hatteras have been analyzed to examine the dynamics of meanders from a Lagrangian viewpoint. Using the float data in conj...
Topographic Influences on Recirculation in the Deep Western Boundary Current：Results from RAFOS Float Trajectories between the Blake–Bahama Outer Ridge and the San Salvador “Gate”
deep western boundary current Blake–Bahama Outer Ridge Topographic Influences San Salvador “Gate”
2008/12/10
Over a period of several years, RAFOS floats were launched into three levels of the deep western boundary current (DWBC) east of the northern Bahamas in order to identify and study any local recircula...
Exchange Geometry Revealed by Float Trajectories in the Gulf Stream
Exchange Geometry Float Trajectories Gulf Stream
2008/12/3
In an effort to understand the extent to which Lagrangian pathways in the Gulf Stream indicate fluid exchange between the stream and its surroundings, trajectories of RAFOS floats are viewed in a fram...
Relation of air mass history to nucleation events in Po Valley, Italy, using back trajectories analysis
air mass history nucleation Po Valley Italy
2008/12/1
In this paper, we study the transport of air masses to San Pietro Capofiume (SPC) in Po Valley, Italy, by means of back trajectories analysis. Our main aim is to investigate whether air masses origina...
STRUCTURE OF TRAJECTORIES OF DISCRETE DISPERSIVE DYNAMICAL SYSTEMS
Compact metric space set-valued mapping trajectory
2008/11/28
In this paper we study global attractors of discrete dispersive dynamical systems generated
by set-valued mappings and the structure of trajectories of these dynamical
systems.
