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…
Free-Form Variational Inference for Gaussian Process State-Space Models
Xuhui Fan, Edwin V. Bonilla, Terence J. O'Kane +1
Gaussian process state-space models (GPSSMs) provide a principled and flexible approach to modeling the dynamics of a latent state, which is observed at discrete-time points via a…
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…
Low-frequency regime transitions and predictability of regimes in a barotropic model
B. T. Nadiga, T. J. O'Kane
Predictability of flow is examined in a barotropic vorticity model that admits low frequency regime transitions between zonal and dipolar states. Such transitions in the model were…
