Stochastic Longshore Current Dynamics
Juan M. Restrepo, Shankar C. Venkataramani
We develop a stochastic parametrization, based on a `simple' deterministic model for the dynamics of steady longshore currents, that produces ensembles that are statistically consi…
Dimension reduction for systems with slow relaxation
Shankar C. Venkataramani, Raman C. Venkataramani, Juan M. Restrepo
We develop reduced, stochastic models for high dimensional, dissipative dynamical systems that relax very slowly to equilibrium and can encode long term memory. We present a variet…
Displacement Data Assimilation
W. Steven Rosenthal, Shankar C. Venkataramani, Arthur J. Mariano +1
We show that modifying a Bayesian data assimilation scheme by incorporating kinematically-consistent displacement corrections produces a scheme that is demonstrably better at estim…
