Global Integrated Polar Prediction System (GIPPS)

Thomas Jung

Alfred Wegener Institute,

Helmholtz Centre for Polar and Marine Research

25 February 2014

  • A short introduction to GIPPS
  • Implementation of GIPPS
    • WWRP Polar Prediction Project
    • WCRP Polar Climate Predictability Initiative
      • Presentation by Vladimir Ryabinin
  • Coordination
  • Global Integrated Polar Prediction System
    • Global: International effort and poles have global influences
    • Integrated: Interconnection between systems and system will be integrated (research, observations and services)
    • Polar prediction will be central
  • Three time scales
    • Short-term prediction (hours to seasonal)
    • Medium-term predictability (seasonal to decadal)
    • Long-term projection of ice mass balance and sea level (centuries)
  • Improved understand of key processes that drive polar weather and climate
  • Improved models
  • Improved data assimilation systems
  • Optimized observing system
  • Improved services (e.g. shipping and long-term planning)
opportunities and risks
  • Some statements from the report:
  • The Arctic is likely to attract substantial investment over the coming decade ($100 bn)
  • The environmental consequences of disasters in the Arctic are likely to be worse than in other regions
  • Significant knowledge gaps across the Arctic need to be closed urgently

Points Raised Earlier:

    • Regular feedback on progress
    • Coordination between PPP and PCPI, and role of ICO for Polar Prediction at AWI
    • Coordination with other organisations
    • Promote GIPPS with
      • Member states (Trust Fund)
      • Funding agencies
    • Consider GIPPS funding from regular WMO budget
