The key objectives of TIGGE
- An enhanced collaboration on development of ensemble prediction,
internationally and between operational centres and universities,
- New methods of combining ensembles from different sources and of correcting for
systematic errors (biases, spread over-/under-estimation),
- A deeper understanding of the contribution of observation, initial and model
uncertainties to forecast error,
- A deeper understanding of the feasibility of interactive ensemble system responding
dynamically to changing uncertainty (including use for adaptive observing, variable
ensemble size, on-demand regional ensembles) and exploiting new technology for grid
computing and high-speed data transfer,
- Test concepts of a TIGGE Prediction Centre to produce ensemble-based predictions of
high-impact weather, wherever it occurs, on all predictable time ranges,
- The development of a prototype future Global Interactive Forecasting System.
