    • Dynamically combining climate models to "supermodel" the tropical Pacific 

      Shen, Mao-Lin; Keenlyside, Noel; Selten, Frank; Wiegerinck, Wim; Duane, Gregory (Peer reviewed; Journal article, 2016-01)
      We construct an interactive ensemble of two different climate models to improve simulation of key aspects of tropical Pacific climate. Our so-called supermodel is based on two atmospheric general circulation models (AGCMs) ...

    • Introduction to focus issue: Synchronization in large networks and continuous media - Data, models, and supermodels 

      Duane, Gregory; Grabow, Carsten; Selten, Frank; Ghil, Michael (Peer reviewed; Journal article, 2017)
      The synchronization of loosely coupled chaotic systems has increasingly found applications to large networks of differential equations and to models of continuous media. These applications are at the core of the present ...

    • Role of atmosphere-ocean interactions in supermodeling the tropical Pacific climate 

      Shen, Mao-Lin; Keenlyside, Noel; Bhatt, Bhuwan Chandra; Duane, Gregory (Peer reviewed; Journal article, 2017-12-29)
      The supermodel strategy interactively combines several models to outperform the individual models comprising it. A key advantage of the approach is that nonlinear improvements can be achieved, in contrast to the linear ...

    • Simulating climate with a synchronization-based supermodel 

      Selten, Frank M; Schevenhoven, Francine Janneke; Duane, Gregory (Peer reviewed; Journal article, 2017-12)
      The SPEEDO global climate model (an atmosphere model coupled to a land and an ocean/sea-ice model with about 250.000 degrees of freedom) is used to investigate the merits of a new multi-model ensemble approach to the climate ...

    • Supermodeling: Synchronization of Alternative Dynamical Models of a Single Objective Process 

      Duane, Gregory; Wiegerinck, Wim; Selten, Frank; Shen, Mao-Lin; Keenlyside, Noel (Chapter, 2018)
      Imperfect models of the same objective process give an improved representation of that process, from which they assimilate data, if they are also coupled to one another. Inter-model coupling, through nudging, or more ...

    • Synchronicity from synchronized chaos 

      Duane, Gregory (Peer reviewed; Journal article, 2015-03-27)
      The synchronization of loosely-coupled chaotic oscillators, a phenomenon investigated intensively for the last two decades, may realize the philosophical concept of “synchronicity”—the commonplace notion that related ...
