WWRP Projects Contributing to Early Warnings for All

The World Weather Research Programme is launching its new implementation plan in January, 2024. A central focus for the next four years (through the end of 2027) will be the value cycle of weather forecasts, wherein we combine physical and social sciences to drive interdisciplinary research that will lead to science that is useful, usable and used by decision makers. Highlights and plans from several projects are presented in this paper, each with an emphasis on the Early Warnings for All initiative, which also has a timeframe of 2027 for the delivery of early-warning capabilities. The projects cover tropical cyclone probabilistic forecasts, convective weather hazards for aviation, urban-scale prediction, hydrometeorology applications, polar prediction for transportation and Indigenous communities, subseasonal applications in agriculture, water and energy, and nowcasting for rainfall hazards over southern Africa. The inclusion of social sciences in WWRP projects will be essential to ensure the understanding of the priorities and needs of various "actors" or users of forecast information. Integrating these priorities into the creation of forecast information will aide in the accessibility and uptake of warning services. With this approach, WWRP aims to not only address aspects of Pillar 2 (forecasting of hazards) of the Early Warnings for All action plan, but also Pillar 1 (disaster risk knowledge) and Pillar 4 (preparedness and response capabilities).
