On a probabilistic evolutionary approach to ocean modelling: From Lorenz-63 to idealized ocean models
Igor Shevchenko, Pavel Berloff
In this study we develop an alternative way to model the ocean reflecting the chaotic nature of ocean flows and uncertainty of ocean models -- instead of making use of classical de…
A hyper-parameterization method for comprehensive ocean models: Advection of the image point
Igor Shevchenko, Pavel Berloff
Idealized and comprehensive ocean models at low resolutions cannot reproduce nominally-resolved flow structures similar to those presented in the high-resolution solution. Although…
A method for preserving nominally-resolved flow patterns in low-resolution ocean simulations: Constrained dynamics
Igor Shevchenko, Pavel Berloff
Inability of low-resolution ocean models to simulate many important aspects of the large-scale general circulation is a common problem. In the view of physics, the main reason for…
A comparison of data-driven approaches to build low-dimensional ocean models
Niraj Agarwal, Dmitri Kondrashov, Peter Dueben +2
We present a comprehensive inter-comparison of linear regression (LR), stochastic, and deep-learning approaches for reduced-order statistical emulation of ocean circulation. The re…
A method for preserving nominally-resolved flow patterns in low-resolution ocean simulations
Igor Shevchenko, Pavel Berloff
Accurate representation of large-scale flow patterns in low-resolution ocean simulations is one of the most challenging problems in ocean modelling. The main difficulty is to corre…
On a minimum set of equations for parameterisations in comprehensive ocean circulation models
Igor Shevchenko, Pavel Berloff
The complexity of comprehensive ocean models poses an important question for parameterisations: is there a minimum set of equations that should be parameterised, on the one hand, t…
Clustering of floating tracers in weakly divergent velocity fields
Konstantin Koshel, Dmitry V. Stepanov, Eugene A. Ryzhov +2
This work focuses on buoyant tracers floating on the ocean surface and treats the geostrophic and ageostrophic surface velocities as the 2D solenoidal (non-divergent) and potential…
