Evolution of particle separation in slowly decorrelating velocity fields
particle separation slowly decorrelating velocity fields
2015/7/14
We consider the evolution of the separation distance between two particles advected by a random velocity field with slowly decaying temporal and spatial correlations in the weak coupling regime. It ha...
Modelling chromospheric line profiles as diagnostics of velocity fields in ω Centauri red giant stars
line profiles globular clusters individual atmospheres mass loss
2010/11/11
Context. Mass loss of ∼ 0.1-0.3 M⊙ from Population II red giant stars (RGB) is a requirement of stellar evolution theory in order to account for several observational evidences in globular clust...
The turnstile mechanism across the Kuroshio current: analysis of dynamics in altimeter velocity fields
Kuroshio current altimeter velocity fields dynamics
2010/4/2
In this article we explore the ability of dynamical systems tools to describe transport in oceanic flows characterized by data sets measured from satellite. In particular we have studied the geometric...
Distinguished hyperbolic trajectories in time-dependent fluid flows:analytical and computational approach for velocity fields defined as data sets
Distinguished hyperbolic trajectories time-dependent fluid flows velocity fields
2009/11/12
In this paper we develop analytical and numerical methods for finding special hyperbolic trajectories that govern geometry of Lagrangian structures in time-dependent vector fields. The vector fields (...
Dispersion and collapse in stochastic velocity fields on a cylinder
Turbulence Lagrangian trajectories Kraichnan ensemble Cylindrical manifolds
2010/4/7
The dynamics of fluid particles on cylindrical manifolds is investigated. The velocity field is obtained by generalizing the isotropic Kraichnan ensemble, and is therefore Gaussian and decorrelated in...
Multiscale estimation of GPS velocity fields
Wavelet transform Satellite geodesy Seismic cycle Transient deformation Kinematics of crustal and mantle deformation
2014/4/9
We present a spherical wavelet-based multiscale approach for estimating a spatial velocity field on the sphere from a set of irregularly spaced geodetic displacement observations. Because the adopted ...
The Mean and Near-Inertial Velocity Fields in a Warm-Core Ring
Mean Warm-Core Ring Near-Inertial Velocity Fields
2009/1/12
Velocity and temperature profiles collected in warm-core ring 82-I in January 1983 are used to describe the mean and fluctuating fields of the ring. The ring was relatively small, containing no Sargas...
