E3SM Community Engagement at European Workshop on Physics-Dynamics Coupling

  • Feature Story
  • Members of the E3SM community helped lead the 3rd Workshop on Physics Dynamics Coupling (PDC18)—an important international workshop focused on optimal strategies for coupling processes in or between the different component models of the earth system. One of the co-organizers was Hui Wan, a global climate modeler from Pacific Northwest National Laboratory (PNNL) and a part of the E3SM community.

    Convened in Reading, UK, in July 2018, PDC18 brought together international scientists from the weather and climate modeling communities who are investigating aspects of modeling that affect the accuracy of solutions. Their work includes new approaches for coupling dynamical and physical (or parameterized) aspects of the models, the effects of resolution, discretization and time-stepping on solution accuracy and convergence, and methods to make solutions more computationally efficient.
