World Meteorological Organization (WMO)-Accredited Infrastructure to Support Operational Climate Prediction
Notice bibliographique
Résumé
Abstract The World Meteorological Organization (WMO) is a specialized agency of the United Nations (UN) system, with an intergovernmental mandate for coordinating the generation and exchange of weather, climate, and water information across its members. WMO has played a vital role in coordinating production and dissemination of weather forecasts from short to medium range whereby global weather forecasts from large operational centers are made available to all WMO members to serve needs of stakeholders at the local level. In recent decades, there has also been an increasing demand for similar forecasts on longer lead times that include prediction on subseasonal, seasonal, and annual to decadal leads. To address the increasing requirements for forecast services by members, WMO has been actively accrediting and coordinating the essential forecast infrastructure that includes provision of forecasts from WMO designated Global Producing Centers and collection of forecasts by Lead Centers to facilitate the dissemination of information and products to WMO members and relevant nongovernmental organizations. Although the basic ingredients of the infrastructure are now in place, the uptake of the forecast information has been suboptimal. To engage the community in developing solutions to enhance the utilization of available information, this paper summarizes the WMO infrastructure for long-range forecasts, particularly for seasonal time scale, and follows with a discussion of current issues that are hindering their uptake. Finally, a set of proposals to advance the utilization of the available information from the WMO long-lead forecast infrastructure are discussed. Significance Statement Because of ongoing changes in climate, the frequency of weather and climate hazards has been increasing and so is the demand to anticipate climate variations with longer lead times. To meet the demand for relevant climate information to manage climate risks for its members, the World Meteorological Organization (WMO) has been proactive in developing and coordinating the required infrastructure based on the latest scientific advances, with cascading of forecast information from global to regional to national scales. The uptake of the forecast information, however, has lagged mainly due to lack of awareness and technical capacities. In this paper, with the intent of engaging the community, the current impediments and solutions to improve the utilization of long-range forecasts are discussed.
