大非洲之角容易出现极端气候条件，因此，气候服务在支持一系列气候敏感部门的决策过程中变得越来越重要。本研究报告旨在全面审查本区域在提供气候服务方面的最新进展、差距和挑战，涉及全球气候服务框架的每一个组成部分。该研究探讨了气候服务提供方面已经取得的各种里程碑。成果包括改善台站网络覆盖范围，提高成员国利用各种数据分析工具和生成常规气候产品的能力。科学的进步和高性能计算的可用性使得从临近预报到季节性时间尺度的预报信息成为可能。此外，客观预报方法在月度和季度预报中的实施，使得将三分之一的预报转化为应用模型成为可能。此外，还制定了通过共同制作、沟通渠道、用户友好界面和传播气候信息等方式促进用户参与的创新办法。尽管在提供气候服务方面取得了重大进展，但仍存在许多挑战和差距需要克服，以确保这些服务有效满足用户的需求。该区域存在的一些差距包括：气候变异性的科学基础研究、能力建设和利益攸关方参与，以及改进的数据管理和质量控制程序。此外，气候信息的交流和传播，包括及时的警报和风险通报，需要改进，以便有效地接触到不同的用户群体。应对这些挑战需要加强伙伴关系，增加能力建设投资，加强气候信息提供者和利害关系方之间的合作，以及开发方便用户的气候产品。弥合这些差距将有助于提高大非洲之角应对气候相关危害和灾害的能力，并支持该区域的可持续发展。
The Greater Horn of Africa is prone to extreme climatic conditions, thus, making climate services increasingly important in supporting decision-making processes across a range of climate sensitive sectors. This study aims to provide a comprehensive review of the recent advances, gaps and challenges in the provision of climate services over the region, for each of the components of the Global Framework for Climate Services. The study explores various milestones that have been achieved toward climate service delivery. The achievements include improvement of station network coverage, and enhancing the capacity of member states to utilize various tools in data analysis and generate routine climate products. The advancement in science, and availability of High-Performance Computing has made it possible for forecast information to be provided from nowcasting to seasonal timescales. Moreover, operationalizing of the objective forecasting method for monthly and seasonal forecasts has made it possible to translate tercile forecasts for applications models. Additionally, innovative approaches to user engagement through co-production, communication channels, user-friendly interfaces, and dissemination of climate information have also been developed. Despite the significant progress that has been made in the provision of climate services, there are still many challenges and gaps that need to be overcome in order to ensure that these services are effectively meeting the needs of users. The research of the science underpinning climate variability, capacity building and stakeholder engagement, as well as improved data management and quality control processes are some of the gaps that exist over the region. Additionally, communication and dissemination of climate information, including timely warnings and risk communication, require improvement to reach diverse user groups effectively. Addressing these challenges will require strengthened partnerships, increased investment in capacity building, enhanced collaboration between the climate information producers and stakeholders, and the development of user-friendly climate products. Bridging these gaps will foster greater resilience to climate-related hazards and disasters in the Greater Horn of Africa and support sustainable development in the region.
