Meander graphs and Frobenius Seaweed Lie algebras
Meander graphs Frobenius Seaweed Lie algebras
2010/11/11
The index of a seaweed Lie algebra can be computed from its associated meander graph. We examine this graph in several ways with a goal of determining families of Frobenius (index zero) seaweed algebr...
The greatest convex minorant of Brownian motion, meander, and bridge
convex minorant Brownian motion
2010/11/19
This article contains both a point process and a sequential description of the greatest convex minorant of Brownian motion on a finite interval. We use these descriptions to provide new analysis of v...
Ultrafast Linear Kinetic Inductive Photoresponse of YBa2Cu3O7-δ Meander-Line Structures by Photoimpedance Measurements
Ultrafast Linear Kinetic Inductive Photoresponse YBa2Cu3O7-δ Meander-Line Structures Photoimpedance Measurements
2010/11/16
We report the experimental demonstration of linear kinetic-inductive photoresponse of thin-film YBa2Cu3O7-{\delta} (YBCO) meander-line structures, where the photoresponse amplitude, full-width-half-m...
In this thesis, we are concerned with the dynamics of spiral wave solutions to Reaction-Diffsion systems of equations, and how they behave when subject to symmetry breaking perturbations. We present a...
Numerical Modeling of Meander and Eddy Formation in the Azores Current Frontal Zone
Eddy Formation Azores Current Frontal Zone
2009/1/7
Numerical experiments with an 11-level primitive equation, finite-difference model in a periodic channel are performed to analyze the properties of unstable finite-amplitude disturbances in an idealiz...
Dynamics of the Kuroshio Large Meander：Two-Layer Model
Two-Layer Model Kuroshio Large Meander
2009/1/6
A simple two-layered in/outflow model is studied to explain the peculiarity of the Kuroshio path. The geometry south of Japan with a length scale L and the characteristic velocity U of the Kuroshio gi...
Gulf Stream Simulations and the Dynamics of Ring and Meander Processes
Gulf Stream Meander and Ring sea surface temperature energy and vorticity budget analyses
2009/1/6
We present here a regional, eddy resolving, numerical study of the dynamics of Gulf Stream Meander and Ring (GSMR) interaction processes. We initialize the Harvard quasi-geostrophic open-boundary mode...
The Hydraulics of Local Separation in a Coastal Current with Application to the Kuroshio Meander
Local Separation Kuroshio Meander Coastal Current
2009/1/5
A hydraulic theory is advanced to explain the large sustained meandering of the Kuroshio Current to the south of Japan. It is shown that in general a promontory induces separation of a coastal current...
Regional Primitive Equation Studies of the Gulf Stream Meander and Ring Formation Region
Gulf Stream Meander Ring Formation Region Primitive equation
2008/12/27
Primitive equation and quasi-geostrophic eddy resolving, open ocean models are used for hindcast studies in the Gulf Stream meander and ring formation region. A feature model approach is used to initi...
Meander Evolution on Piecewise-Uniform, Quasi-geostrophic Jets
Meander Evolution Piecewise-Uniform Quasi-geostrophic Jets
2008/12/24
A variety of simple, two-layer representations of a quasi-geostrophic jet along a vorticity front are initialized with a simple meander. The subsequent evolution of the jet is followed and related to ...
Observations of Gulf Stream Meander-Induced Disturbances
Gulf Stream Meander-Induced Disturbances
2008/12/17
Using moored array data collected across the Gulf Stream at 55°W, the author has investigated the dynamic signatures of the velocity fluctuations at the thermocline (550 m) and near-bottom (4000 m) le...
Variations of Current Path, Velocity, and Volume Transport of the Kuroshio in Relation with the Large Meander
non-large-meander large-meander
2008/12/12
The variations of the Kuroshio Current path and their relations with current velocity, volume transport, and upstream position of the Kuroshio are examined using sea level data. After the long-time, n...
Model Study of Flow Conditions Causing the Large Meander of the Kuroshio South of Japan
large-meander Flow Conditions non-large-meander
2008/12/11
The upstream conditions for large-meander (LM) and non-large-meander (NLM) paths of the Kuroshio south of Japan were examined by calculating the current axis with a steady model imposed upstream flow ...
The Cross-Stream Potential Vorticity Front and Its Role in Meander-Induced Exchange in the Gulf Stream
Cross-Stream Potential Vorticity Front Meander-Induced Exchange Gulf Stream
2008/6/9
The potential vorticity (PV) front observed in the upper thermocline at the northern edge of the Gulf Stream has been thought of as an inhibitor to lateral motion of parcels on isopycnals. The role of...
