A major research challenge of 21 century is to reduce and mitigate natural disasters and to realise the societal and economic benefits of improved weather forecasts. THORPEX will address this research challenge, thereby contributing to the development of a future truly integrated Global Interactive Forecast System (GIFS), which would generate numerical probabilistic products, available to all nations including developing countries. "Global" signifies both global participation and global application; the system would in principle use global and regional models as appropriate. An "Interactive" forecast system changes according to situation and user needs: all parts of the system from observations through data assimilation and the forecast production to the end-user applications are integrated, adaptive, and interactive.

The THORPEX Interactive Grand Global Ensemble (TIGGE) will provide the facility to test these concepts in a prototype GIFS, and at the same time provide a framework for international collaboration in the development and testing of ensemble prediction systems. TIGGE is planned to provide the main prediction tool in THORPEX Demonstration Projects. These activities will contribute to the international development and testing of the GIFS.

One of the issues that will be discussed during the WS is the definition of the TIGGE Working Group (WG) that will direct and oversee the TIGGE project. The duties of the TIGGE-WG will include:

Design structure of TIGGE dataset considering potential scientific research subprojects and possible real-time applications
Prioritise requirements of different subprojects
Monitor work and results done with TIGGE data
Report on progress to THORPEX, funding bodies, data providers
Feed progress into development of GIFS
Take necessary action to ensure success of project

One of the first tasks of the TIGGE-WG will be to define the scientific requirements for TIGGE and then to plan and develop the infrastructure accordingly.
