Evolution of Bearing Determination in HF Current Mapping Radars
Bearing Determination HF Current Mapping Radars
2015/8/10
Nearly all target detection "radars" in existence operate at microwave frequencies because their wavelengths are small enough that compact antennas provide both good angular resolution and high sensit...
Evolution and Revolution in Measuring Ocean Optical Properties
Evolution and Revolution Ocean Optical
2015/8/4
Measuring and interpreting the optical properties of ocean waters has been, and continues to be a challenging endeavor in oceanography. Just as the measurements of temperature~ salinity and density (T...
Bore formation,evolution and disintegration into solitons in shallow inhomogeneous channels
Bore formation evolution disintegration shallow inhomogeneous channels
2009/11/12
The propagation of nonlinear surface waves in channels of smoothly variable in space cross section is studied theoretically and by means of numerical computations. The mathematical model describing wa...
A Dynamical-Numerical Study of the Formation and Evolution of Large-Scale Ocean Anomalies
sea surface temperature Formation Large-Scale Ocean Anomalies
2009/2/23
To identify oceanic processes responsible for the formation and evolution of large-scale thermal anomalies, a series of initial-value model simulations are carried out using a 10-level primitive equat...
The Propagation and Evolution of Cyclonic Gulf Stream Rings
Cyclonic Gulf Stream Rings Evolution Propagation
2009/2/13
Numerical simulations of the propagation of cyclonic Gulf Stream rings are made using a primitive equation β-plane model of a flat-bottomed two-layer ocean with a rigid lid. Initially circular eddies ...
On the Evolution of Isolated, Nonlinear Vortices
Isolated Nonlinear Vortices axially symmetric vortex
2009/2/13
The evolution of an isolated, axially symmetric vortex is calculated with a quasi-geostrophic, adiabatic, hydrostatic. β-plane, two vertical mode model. The circumstances of greatest interest are thos...
The Middle Atlantic Bight Cold Pool：Evolution of the Temperature Structure During Summer 1979
Middle Atlantic Bight Middle Atlantic Bight Cold Pool Temperature Structure
2009/2/8
Temperature data spanning the entire Middle Atlantic Bight (MAB) during 1979 are used to study the structure and evolution of the cold pool. The Nantucket Shoals and New England Shelf appear to be the...
Generation and Evolution of a Cyclonic Ring at Drake Passage in Early 1979
Cyclonic Ring Drake Passage
2009/2/7
An equatorward meander in the Antarctic Polar Front at Drake Passage was observed to amplify and pinch off during January and early February 1979, forming a cold-core. cyclonic current fins with a rad...
On the Evolution of Nonlinear Planetary Eddies Larger than the Radius of Deformation
Nonlinear Planetary Eddies Larger planetary eddies
2009/2/7
The properties of a new equation governing the evolution of planetary eddies larger than the radius of deformation are numerically investigated. Two types of dynamical balances showing remarkable soli...
The Birth and Evolution of Eastward-Propagating Modons
eastward-propagating modon mesoscale eddy
2009/2/7
This paper addresses the tendency for an eastward-propagating modon to form from a mesoscale eddy which has an inclined vertical axis and different senses of rotation in the upper and deep oceans. Thi...
This paper presents an analytical investigation of nonlinear internal wave evolution in the Sulu Sea. A solitary wave theory that describes tie evolution of internal solitons has been developed and ex...
Numerical solutions are examined for nearly axisymmetric geopotential monopole vortices whose vertical structure is essentially confined to the lowest few vertical modes. The vortex environment is a r...
