The DYAMOND Initiative


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.

DYAMOND addresses two main questions:

  • 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 are initialized with the global (9 km) meteorological analysis taken from the ECMWF for 1st August 2016, and the DYAMOND Winter simulations are started from 20th January 2020.

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).

Due to the joint interest in high-resolution simulations, ESiWACE strongly supports and interacts with DYAMOND. Within this scope, the German Climate Computing Center (DKRZ) agreed to host the simulation output and serves as an analysis hub for the community.

Experiment Phases

After a huge resonance for the DYAMOND summer simulations, we are now performing and collecting the output from the DYAMOND winter simulations.
