Turbulence and Rossby Wave Dynamics with Realizable Eddy Damped Markovian Anisotropic Closure
Jorgen S. Frederiksen, Terence J. O'Kane
The theoretical basis for the Eddy Damped Markovian Anisotropic Closure (EDMAC) is formulated for two-dimensional anisotropic turbulence interacting with Rossby waves in the presen…
Statistical Dynamics and Subgrid Modelling of Turbulence: From Isotropic to Inhomogeneous
Jorgen S. Frederiksen, Vassili Kitsios, Terence J. O'Kane
Turbulence is the most important, ubiquitous, and difficult problem of classical physics. Feynman viewed it as essentially unsolved, without a rigorous mathematical basis to descri…
Realizable Eddy Damped Markovian Anisotropic Closure for Turbulence and Rossby Wave Interactions
Jorgen S Frederiksen, Terence J O'Kane
A realizable Eddy Damped Markovian Anisotropic Closure (EDMAC) is presented for the interaction of two dimensional turbulence and transient waves such as Rossby waves. The structur…
Covariant Lyapunov Vectors and Finite-Time Normal Modes for Geophysical Fluid Dynamical Systems
Jorgen S Frederiksen
Dynamical vectors characterizing instability and applicable as ensemble perturbations for prediction with geophysical fluid dynamical models are analysed. The relationships between…
Markovian inhomogeneous closures for Rossby waves and turbulence over topography
Jorgen S. Frederiksen, Terence J. O Kane
Manifestly Markovian closures for the interaction of two-dimensional inhomogeneous turbulent flows with Rossby waves and topography are formulated and compared with large ensembles…
Quasi-diagonal Inhomogeneous Closure for Classical and Quantum Statistical Dynamics
Jorgen S. Frederiksen
The Quasi-diagonal Direct Interaction Approximation (QDIA) closure equations are formulated for inhomogeneous classical and quantum fields interacting through dynamical equations w…
