Subgrid parameterizations of ocean mesoscale eddies based on Germano decomposition

Pavel Perezhogin, Andrey Glazunov

Ocean models at intermediate resolution (1/4 degree), which partially resolve mesoscale eddies, can be seen as Large eddy simulations (LES) of the primitive equations, in which the…

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…

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…

Order out of chaos: Shifting paradigm of convective turbulence

Sergej S Zilitinkevich, Evgeny Kadantsev, Irina Repina +2

Turbulence is ever produced in the low-viscosity/large-scale fluid flows by the velocity shears and, in unstable stratification, by buoyancy forces. It is commonly believed that bo…

A New Mathematical Framework for Atmospheric Blocking Events

Valerio Lucarini, Andrey Gritsun

We use a simple yet Earth-like atmospheric model to propose a new framework for understanding the mathematics of blocking events. Analysing error growth rates along a very long mod…

Eddy energy sources and mesoscale eddies in the Sea of Okhotsk

D. V. Stepanov

Based on an eddy-permitting ocean circulation model, the eddy kinetic energy (EKE) sources are studied in the Sea of Okhotsk. An analysis of the spatial distribution of the EKE sho…

Fluctuations, Response, and Resonances in a Simple Atmospheric Model

Andrey Gritsun, Valerio Lucarini

We study the response of a simple quasi-geostrophic barotropic model of the atmosphere to various classes of perturbations affecting its forcing and its dissipation using the forma…

Variational Data Assimilation for Optimizing Boundary Conditions in Ocean Models

Christine Kazantsev, Eugene Kazantsev, Mikhail Tolstykh

The review describes the development of ideas Gury Ivanovich Marchuk in the field of variational data assimilation for ocean models applied in particular in coupled models for long…
