在世界许多地方，试验台已成为推动知识和能力从研究转移到业务天气预报的不可或缺的组成部分。最近通过非洲气象信息和预报技术科学方案在热带非洲进行了第一个高影响天气试验台，来自塞内加尔、加纳、尼日利亚、肯尼亚、联合王国以及国际和泛非组织的研究人员和预报员参加了试验。该试验台的目的是与业务预报员一起试用新的预报和临近预报产品，为未来的研究提供信息，并作为热带地区未来试验台的模板。非洲SWIFT测试平台在整个过程中整合了用户和研究人员，以促进开发基于影响的预测方法和由业务和用户投入驱动的新研究思路。这些新产品主要是基于卫星的临近预报系统和在全球和区域对流允许的范围内的集合预报。在试验平台之前，这两种技术都没有在非洲参与国投入使用。该测试平台通过包括渔业、农业、航空和电力部门在内的激烈用户互动获得了建设性的积极反馈。在试验台之后，已制作了最后一套建议的热带非洲卫星临近预报标准操作程序。试验平台使供资机构和组织主任注意到改进预测的直接好处。测试平台的交付加强了每个国家参与大学和天气预报机构之间以及国际之间的伙伴关系，这是确保测试平台成果持久性的关键。
Testbeds have become integral to advancing the transfer of knowledge and capabilities from research to operational weather forecasting in many parts of the world. The first high-impact weather testbed in tropical Africa was recently carried out through the African Science for Weather Information and Forecasting Techniques (SWIFT) program, with participation from researchers and forecasters from Senegal, Ghana, Nigeria, Kenya, the United Kingdom, and international and pan-African organizations. The testbed aims were to trial new forecasting and nowcasting products with operational forecasters, to inform future research, and to act as a template for future testbeds in the tropics. The African SWIFT testbed integrated users and researchers throughout the process to facilitate development of impact-based forecasting methods and new research ideas driven both by operations and user input. The new products are primarily satellite-based nowcasting systems and ensemble forecasts at global and regional convection-permitting scales. Neither of these was used operationally in the participating African countries prior to the testbed. The testbed received constructive, positive feedback via intense user interaction including fishery, agriculture, aviation, and electricity sectors. After the testbed, a final set of recommended standard operating procedures for satellite-based nowcasting in tropical Africa have been produced. The testbed brought the attention of funding agencies and organizational directors to the immediate benefit of improved forecasts. Delivering the testbed strengthened the partnership between each country’s participating university and weather forecasting agency and internationally, which is key to ensuring the longevity of the testbed outcomes.
