WWRP 1 The World Weather Research Programme (WWRP) Long Term Plan including the development of Regional Environmental Prediction Systems Gilbert Brunet and Dave Parsons CAS-XV Technical Conference Incheon, Republic of Korea, November 2009,
WWRP 2 Long-term objectives of the WWRP To improve public safety and economic productivity by accelerating research on the prediction of high-impact weather; To demonstrate improvements in the prediction of weather, with emphasis on high-impact events through the exploitation of advances in scientific understanding, observational network design, data assimilation and modelling techniques and information systems; To improve understanding of atmospheric processes of importance to weather forecasting through the organization of focused research programmes (e.g., WWRP Strategic Plan); To encourage the utilization of relevant advances in weather prediction systems to the benefit of all WMO Programmes and all Members; and To maintain a strong focus on training opportunities for young scientists, so that as many countries as possible will be able to contribute to and benefit from the research advances.
4 WWRP Long Term Challenges: Nowcasting Research (NR) Use the latest observational technologies to detect and forecast weather over the 0-6 hour time frame for rapidly evolving small scale phenomena that realize high-impact over short periods. Develop automated approaches for the rapid detection and effective dissemination of information; and Develop linkages and on-going compatibility with longer time scale forecasts in the context of a unified approach to forecasting.

WWRP 19 and the list of environmental prediction applications continues… To protect Human Health - Daily and High Impact Weather Forecasts - Water quality/quantity forecasts - Air Quality Forecasts - Flooding conditions - Urban meteorology (heat wave, security) For government efficiency and effectiveness in delivering public and national security services - Operations, domestically and internationally - Coast Guard operations, ice and storm surge forecasts
WWRP 20 and … For energy production, distribution and strategic network management - Wind energy climatology - Wind power forecasts for wind farms nationally - Peak power demand forecasts in heat waves or cold spells to better manage grids and distribution networks - Regional climate change scenarios for long term watershed management (reservoirs) so that strategic funding decisions can be made by financial syndicates For other industrial sectors - Transport (e.g., road, maritime and aviation security) - Tourism and Recreation (e.g., avalanche forecasting, seasonal temperature) - Agriculture (e.g., soil mosisture, futures market, pest control, micro-farming and droughts) - Construction - Forestry (e.g., pest control and forest fire)
WWRP 21 and finally … For validation and enforcement of international protocols, international emergencies - Volcanic Ash modeling - Nuclear Test Ban Treaty - Contaminant trajectories - Water level regulation and adaptive management For the health of people and sustainability of ecosystems - In climate change scenario modes, we can now project decades ahead the state of major watershed and surrounding ecosystems - We can simulate long range transport of toxics and pollutants from any part of the globe
WWRP 22 World Weather Research Programme Strategic Plan Available on the WWRP webpage at « At the dawn of this new century, significant research and development challenges remain to be met before acceptable meteorological and environmental forecasts can be produced worldwide over every spatial scale (from urban to planetary) and time scale (from a few minutes to seasons). The success of this endeavour will depend, of course, on the collaboration, commitment, excellence and strength of the weather, climate and Earth-system research communities. On this point, the 20th century track record provides a solid base for confidence »
