The initiative DYAMOND (DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic Domains) sets up a framework for the intercomparison of global storm-resolving models, i.e. an emerging class of atmospheric circulation models.  Through their explicit resolution of the major modes of atmospheric heat transport, they endeavor to represent the most important scales of the full three-dimensional fluid dynamics of the atmospheric circulation.

The idea of DYAMOND arose in October 2017 and started as a joint initiative between the Max Planck Institute for Meteorology (MPI-M, Bjorn Stevens) and University of Tokyo (Masaki Satoh). Further impulse was given through the involvement of US participants (Chris Bretherton, University of Washington). Furthermore the initiative is supported by Deutscher Wetterdienst (DWD) through the Hans Ertel Centre for Weather Research (HErZ) (Daniel Klocke).

DYAMOND addresses two main questions:

  • Where do the storm-resolving simulations agree and provide deeper insights into the climate system?
  • How sensitive are the simulations to a particular implementation?
  • What are performance and analysis bottle necks associated with global storm-resolving models?

Up to now, two experimental phases have been implemented: the DYAMOND Summer simulations covering a boreal summer periode and the second pahse  DYAMOND Winter covering a boreal winter periode. Within both phases, experiments are initialized with global meteorological analysis taken from the ECMWF.
