The Moving Boundaries of Sea Level Change:Understanding the Origins of Geographic Variability
Sea Level Change Geographic Variability
2015/7/9
As ice sheets gain or lose mass, and as water moves between the continents and the ocean, the solid Earth deforms and the gravitational field of the planet is perturbed. Both of these effects lead to ...
Framed-Quadtree Path Planning for an Underwater Vehicle with the Task of Tracking a Moving Target
regular grid framed quadtree data structure algorithm efficiency
2011/9/9
An autonomous underwater vehicle (AUV) must use an algorithm to plan its path to distant, mobile offshore objects. Because of the uneven distribution of obstacles in the real world, the efficiency of ...
Using a linear array to estimate the velocity of underwater moving targets
underwater velocity measurement linear array direction of arrival (DOA) deterministic maximum likelihood signal phase matching
2011/9/13
A new method uses a linear array that takes advantage of underwater physical sound fields to estimate the velocity of an underwater moving target. The mathematical model was established by considering...
Observation of the Structure on Moving Gust Patterns Over a Water Surface (“Cat's Paws”)
Moving Gust Patterns Water Surface
2009/4/2
We report on observations of near-surface Velocity, temperature, stress, buoyancy, and surface wave fluctuations, including successive short-time averages of coherences, phases, autospectra, and proba...
Impingement of Internal Waves from Below onto a Moving Mixed Surface Layer
Internal Waves Moving Mixed Surface Layer
2009/3/7
Discussion of the generation of internal waves by tidal flow over bottom topography concludes that isobath convergence has an important effect on wave intensity near the sea surface, and also predicts...
The Fission and Disintegration of Internal Solitary Waves Moving over Two-Dimensional Topography
Internal Solitary Waves Moving Two-Dimensional Topography
2009/2/23
The propagation of long internal waves over two-dimensional topography is discussed. A two-dimensional version of the Korteweg-deVries equation is derived with variable coefficients which depend on th...
Continental Shelf Circulation Induced by a Moving, Localized Wind Stress
Continental Shelf Circulation Moving Wind Stress
2009/2/9
A linear, two-dimensional model of a rotating, stratified fluid is constructed to investigate the circulation induced by a moving, localized line of surface stress. This model is used to analyze the e...
Internal Wave Wake of a Moving Storm. Part I. Scales, Energy Budget and Observations
Internal Wave Moving Storm
2009/2/5
The ocean's baroclinic response to a steadily moving storm is analyzed using a numerical model for an inviscid, multi-layered fluid. This first part of a two-part study gives a detailed account of the...
On the Response of the Ocean to a Moving Storm：The Nonlinear Dynamics
Nonlinear Dynamics Moving Storm
2009/1/22
A novel and efficient numerical method is used to investigate the nonlinear equations of motion for the upper layer of a two-layer ocean in which the lower layer is infinitely deep and at rest. The ef...
On the Response of the Ocean to a Moving Storm：Parameters and Scales
Moving Storm Parameters Scales
2009/1/19
This paper has two purposes: One is to present a new and efficient multilevel numerical model for calculating the response of the ocean to a moving storm; the second is to show how, on a time scale of...
A solution for a concentrated line front translating at speed U is given. It is shown that the frequency is near-inertial if Uc1, where c1 is the long internal wave speed of the first baroclinic mode....
The upper ocean's response to three hurricanes [Norbert (1984), Josephine (1984) and Gloria (1985)] is examined using field observations and a numerical ocean model. Our goal is to describe the physic...
Barotropic Response of the Labrador/Newfoundland Shelf to a Moving Storm
Barotropic Response Moving Storm Newfoundland
2008/10/28
The barotropic response of the Labrador and Newfoundland shelves to a moving storm over the Labrador Sea is investigated using a linear barotropic ocean model with realistic coastline and topography. ...
Numerical simulation of viscous liquid sloshing by moving-particle semi-implicit method
sloshing liquid tank viscous fluid incompressible fluid free surface meshless moving-particle semi-implicit method (MPS)
2011/9/14
A meshless numerical simulation method, the moving-particle semi-implicit method (MPS) is presented in this paper to study the sloshing phenomenon in ocean and naval engineering. As a meshless method,...
Climate Variability of the Equatorial Thermocline Inferred from a Two-Moving-Layer Model of the Ventilated Thermocline
Climate Variability Equatorial Thermocline Two-Moving-Layer Model Ventilated Thermocline
2008/7/3
A two-moving-layer model is used to examine the structure of the equatorial thermocline and its connection with the extratropical thermocline. It is found that cooling (warming) in extratropics genera...
