Forecasting of Mesoscale Eddies in the Kuroshio Extension Based on Temporal Modes-Enhanced Neural Network

Journal of Marine Science and Engineering, 2023
Mesoscale eddies are a common occurrence in the Kuroshio Extension (KE) that have a major impact on the levels of salinity and heat transport in the Northwest Pacific, the strength of the Kuroshio jet, and the fluctuations of the Kuroshio’s trajectory ...

Global Estimation of the Eddy Kinetic Energy Dissipation From a Diagnostic Energy Balance

Geophysical Research Letters, 2023
Mesoscale eddies dominate the ocean kinetic energy reservoir. However, how and where this energy flows out from the mesoscale remains uncertain. Here, a simplified mesoscale energy budget is used where sources due to baroclinic instability are balanced ...

Large eddy simulation of ocean mesoscale eddies

Mesoscale eddies produce lateral (2D) fluxes that need to be parameterized in eddy-permitting (1/4-degree) global ocean models due to insufficient horizontal resolution. Here, we systematically apply methods from the 3D LES community to parameterize lateral vorticity fluxes produced by mesoscale eddies leveraging an explicit filtering approach together

The Mesoscale SST–Wind Coupling Characteristics in the Yellow Sea and East China Sea Based on Satellite Data and Their Feedback Effects on the Ocean

Journal of Marine Science and Engineering
The mesoscale interaction between sea surface temperature (SST) and wind is a crucial factor influencing oceanic and atmospheric conditions. To investigate the mesoscale coupling characteristics of the Yellow Sea and East China Sea, we applied a locally ...

Complexity of Mesoscale Eddy Diffusivity in the Ocean

Geophysical Research Letters, 2020
Abstract Stirring of water by mesoscale currents (“eddies”) leads to large‐scale transport of many important oceanic properties (“tracers”). These eddy‐induced transports can be related to the large‐scale tracer gradients, using the concept of turbulent diffusion.

Mesoscale Eddy Properties in Four Major Western Boundary Current Regions

Remote Sensing
Oceanic mesoscale eddies are a kind of typical geostrophic dynamic process which can cause vertical movement in water bodies, thereby changing the temperature, salinity, density, and chlorophyll concentration of the surface water in the eddy.

A physics-informed machine learning approach for predicting acoustic convergence zone features from limited mesoscale eddy data

Frontiers in Marine Science
Mesoscale eddies are prevalent mesoscale phenomena in the oceans that alter the thermohaline structure of the ocean, significantly impacting acoustic propagation patterns. Accurately predicting acoustic convergence zone features has become an urgent task,

Mesoscale Ocean Eddy-Wind Interaction

, 2022
A surface wind stress that includes the ocean surface current (known as relative wind stress) can result in a damping of eddy energy. A weakened eddy field has significant implications for the regional and global ocean circulation. Eddy energy budget-based parameterisations currently employ an arbitrary dissipation rate, leaving some uncertainty in ...
