Aspects of EC-Earth

• Seamless prediction strategy (weather to climate)
• High resolution/Well evaluated synoptic
  variability
• Advanced dynamics and computational architecture
• - Semi-Lagrangian/Semi Implicit dynamics
  (T159, L62 ?T3600s)
• - MPI and OpenMP efficient parallelisation
• State-of-the-art NWP parameterisations
• Atmosphere and Ocean Assimilation (NEMOvar)
  system built-in
• Easier collaboration NWP to climate scales
• Common architecture/model/diagnostics across
• consortium members and with ECMWF
• Possible to pool science and computational
  resources
