Data-Driven Model Identification Using Time Delayed Nonlinear Maps for Systems with Multiple Attractors
Athanasios P. lliopoulos, Evelyn Lunasin, John G. Michopoulos +2
This study presents a method, along with its algorithmic and computational framework implementation, and performance verification for dynamical system identification. The approach…
Probabilistic Eddy Identification with Uncertainty Quantification
Jeffrey Covington, Nan Chen, Stephen Wiggins +1
Mesoscale eddies are critical in ocean circulation and the global climate system. Standard eddy identification methods are usually based on deterministic optimal point estimates of…
Launching Drifter Observations in the Presence of Uncertainty
Nan Chen, Evelyn Lunasin, Stephen Wiggins
Determining the optimal locations for placing extra observational measurements has practical significance. However, the exact underlying flow field is never known in practice. Sign…
Lagrangian Descriptors with Uncertainty
Nan Chen, Evelyn Lunasin, Stephen Wiggins
Lagrangian descriptors provide a global dynamical picture of the geometric structures for arbitrarily time-dependent flows with broad applications. This paper develops a mathematic…
An Efficient Continuous Data Assimilation Algorithm for the Sabra Shell Model of Turbulence
Nan Chen, Yuchen Li, Evelyn Lunasin
Complex nonlinear turbulent dynamical systems are ubiquitous in many areas. Recovering unobserved state variables is an important topic for the data assimilation of turbulent syste…
A data assimilation algorithm: the paradigm of the 3D Leray-alpha model of turbulence
Aseel Farhat, Evelyn Lunasin, Edriss S. Titi
In this paper we survey the various implementations of a new data assimilation (downscaling) algorithm based on spatial coarse mesh measurements. As a paradigm, we demonstrate the…
