During this two day meeting we will discuss the potential advantages and disadvantages of adaptive meshing of the atmosphere and ocean and the remaining scientific and technical challenges that must be met before these techniques are widely accepted for operational use. We will also discuss a proposal to hold a Newton Institute programme in order to overcome some of the remaining obstacles.

Climate models cannot resolve tropical cyclones, convective clouds and precipitation in the atmosphere or continental shelves, marginal sea overflows and boundary currents in the oceans because these processes occur at small scales and interact with the global dynamics.

  • Isotropic or anisotropic mesh adaptation strategies in the presence of ubiquitous small-scale waves and turbulent structures present it the atmosphere and ocean
  • Preservation of geostrophic and hydrostatic balance under adaptation
  • Maintaining conservation properties under adaptation
  • Spurious wave reflection and refraction from mesh inhomogeneity
  • Producing algorithms which scale on ever more massively parallel computers
  • Physical parametrisations that are accurate over a wide range of resolutions and do not spuriously trigger or inhibit mesh adaptivity
  • Data assimilation on a multi-scale mesh
  • The additional cost of storing and navigating a changing, possibly unstructured, mesh

Speakers will include:

  • Dr Bill Skamarock (NCAR)
  • Prof Christiane Jablonowski (University of Michigan)
  • Prof Frank Giraldo (Naval Postgraduate School, Monterey)
  • Prof Vincent Legat (Universite' catholique de Louvain, Belgium)
  • Prof Omar Ghattas (University of Texas at Austin)
  • Prof John Thuburn (Exeter University, UK)
  • Dr Terry Davies (Met Office, UK)
  • Dr Matthew Piggott (Grantham Institute, Imperial College London)
  • Dr Jörn Behrens (Alfred Wegener Institute, Germany)
  • Prof Sir David Wallace (Newton Institute, Cambridge)

Discussion and Poster Sessions:

There will be an opportunity for participants to submit posters for display at the event. The meeting will include poster sessions and break out discussions on the content of a Newton Institute programme proposal.
