General information and objectives

WHY?
To reduce and mitigate natural disasters by transforming timely and accurate weather forecasts into specific and definite information in support of decisions that produce the desired societal and economic outcomes.
    1) Extending the range of skilful weather forecasts to time scales of value in decision-making (up to 14 days) using probabilistic ensemble forecast techniques;
    2) Developing accurate and timely weather warnings in a form that can be readily used in decision-making support tools;
    3) Assessing the impact of weather forecasts and associated outcomes on the development of mitigation strategies to minimise the impact of natural hazards.


WHAT WILL IT DO?
THORPEX will conduct a series of regional and global projects including various experiments on targeted satellite and in-situ observations, data assimilation, numerical weather prediction systems and demonstrations of social and economic outcomes.
    1) Advance the knowledge of global-to-regional influences on the initiation, evolution, and predictability of high-impact weather; Design the strategy for interactive forecasting and targeted observations thus contributing to the process of evolving the WMO Global Observing System (GOS) which is recognized as a core component of future Global Earth Observation System of Systems (GEOSS); 
    2) Create and evaluate systems for the assimilation of targeted observations from satellites and in-situ measurements;
    3) Accelerate improvements of the accuracy of weather forecasts; test and demonstrate effectiveness of a multinational multi-model multi-analysis global ensemble forecasting system; 
    4) Improve and demonstrate decision support tools, which utilise advanced forecasting products, in the most representative social and economic sectors. 


WHERE?
Globally focusing specifically on the extra-tropical and tropical Pacific and Atlantic, the Pacific-Indian Ocean warm pool, and Polar regions.

WHO PARTICIPATES and WHO BENEFITS?
National Meteorological and Hydrological Services (NMHSs operational forecast and research entities and consumers of products and services) as well as academic institutions of WMO Members including developing and least developed countries; international organizations (ECMWF, EUMETNET, etc.), initiatives (International Polar Year, GEOSS) and other contributors.HOW IS IT ORGANIZED? The CAS International Core Steering Committee (ICSC) and International Science Steering Committee (ISSC) lead THORPEX in coordination with the CAS Science Steering Committee for the WWRP, joint CAS/JSC Working Group on Numerical Experimentation (WGNE), and the WMO Commission for Basic Systems (CBS). North American, European and Asian Regional Committees coordinate regional activities.
