Major Atlantic ocean current system might be approaching critical threshold
weather systems worldwide river stability current system collapses global warming freshwater inflow
2021/8/6
A major Atlantic ocean current -- the Atlantic Meridional Overturning Circulation, or AMOC -- may have been losing stability in the course of the last century, according to new research. A potential c...
Drilling into the seabed beneath Earth’s most powerful ocean current（图）
climate change seabed beneath Earth powerful ocean current
2019/10/30
The Antarctic Circumpolar Current is the planet's most powerful and arguably most important current. It is the only current to flow clear around the globe without being diverted by any landmass.It con...
Study Finds Major Ocean Current is Widening As Climate Warms
Ocean Current Widening Climate Warms
2016/11/29
A new study by University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers found that the Indian Ocean’s Agulhas Current is getting wider rather than strengthening. The fi...
Applications of GODAE Ocean Current Forecasts to Search and Rescue and Ship Routing
GODAE Ocean Current Search and Rescue
2015/7/6
As GODAE ocean forecast systems progress, their contributions toward improving the safety and efficiency of operations at sea will increase. In this article, we review present uses of GODAE ocean fore...
Formation of Meanders, Fronts, and Cutoff Thermal Pools in a Baroclinic Ocean Current
Baroclinic Ocean Current Cutoff Thermal Pools
2009/3/24
Using an analytical model similar to that previously applied by the authors to the atmosphere, calculations are made showing how second-order, nongeostrophic effects can modify a two-layer baroclinic ...
Description of Wind and of Upper Ocean Current and Temperature Variations on the Continental Shelf off Northwest Africa during March and April 1974
Upper Ocean Current Temperature Variations Continental Shelf off Northwest Africa
2009/3/7
Measurements of winds and of near-surface temperatures and currents made during March and April 1974 on the continental shelf off northwest Africa were extremely time-dependent. Alternating land and s...
On the Interpretation of Ocean Current Spectra, Part II：Testing Dynamical Hypotheses
Ocean Current Spectra Dynamical Hypotheses
2009/2/23
Three examples are chosen to illustrate how the several spectrum representations in Part 1 can be used to test whether a proposed dynamical mechanism is supported by a given set of observations. The e...
On the Interpretation of Ocean Current Spectra. Part 1：The Kinematics of Three-Dimensional Vector Time Series
Ocean Current Spectra Three-Dimensional Vector Time Series
2009/2/23
A general method for representing and interpreting the spectra of three-dimensional vector time series is outlined. Part I contains the formalism for the kinematic interpretation of a single vector ti...
Characteristics of Surface Current Flow Inferred from a Global Ocean Current Data Set
ocean-current data set Surface Current Flow
2009/2/7
A seasonal global ocean-current data set (OCDS) digitized on a 5° grid from long-term mean shipdrift-derived currents from pilot charts is presented and described. Annual zonal means of v-component cu...
On the Response of Short Ocean Wave Components at a Fixed Wavenumber to Ocean Current Variations
Short Ocean Wave Fixed Wavenumber Ocean Current Variations
2009/1/21
This paper is concerned with the patterns in the degree of saturation of short wind-generated waves (at scales much smaller than those of the spectral peak but large compared with the capillary scales...
