国家海洋环境预报中心自主研发的“妈祖・海浪”预报技术成功应用，故障率低于1%
近日，国家海洋环境预报中心自主研发的“妈祖・海浪”预报模式取得重要进展，该模式已成功应用于海浪数值预报业务化产品中。据了解，“妈祖・海浪”模式是自然资源部重大创新工程海洋预报“芯片”工程的系列科技攻关任务之一，由国家海洋环境预报中心和中国海洋大学共同承担。该模式瞄准海浪数值预报严重依赖国外模式、自主技术缺失、计算耗时长等突出问题，集中开展自主技术攻关。
“妈祖・海浪”模式包含计算网格生成、数值计算、后处理与产品制作、精度检验等模块，系统功能齐备完整。该模式可提供未来7天全球及区域海浪数值预报业务化产品，其业务化试运行结果显示，“妈祖・海浪”模式高效可靠，故障率低于1%，与现有业务化海浪数值预报模式相比，计算能效显著提升，预报精度明显提高，满足业务化运行要求。
值得一提的是，在今年第3号超强台风“格美”影响期间，我国首次将自主研发的“妈祖・海浪”模式用于海浪预警，为海浪的及时、准确预警提供了重要支撑。这一技术的成功应用，标志着我国在海洋环境预报领域实现了新的突破，对于保障海上交通安全、海洋资源开发和海洋灾害防御具有重要意义。

News Title: “Mazu Wave” Forecasting Technology Breakthrough: Fault Rate Below 1% Aids Accurate Sea Wave Warning
Keywords: Mazu Wave, Autonomous Forecasting, Low Fault Rate
News Content:
The “Mazu Wave” forecasting technology developed independently by the National Marine Environmental Forecasting Center has been successfully applied, with a fault rate below 1%.
Recently, the “Mazu Wave” forecasting mode developed independently by the National Marine Environmental Forecasting Center has made significant progress. This mode has been successfully applied to operational sea wave numerical forecasting products. It is understood that the “Mazu Wave” mode is part of the major innovation project for marine forecasting by the Ministry of Natural Resources, known as the “chip” project, which is jointly undertaken by the National Marine Environmental Forecasting Center and Ocean University of China. The mode focuses on addressing critical issues such as the severe dependence on foreign models for sea wave numerical forecasting, the absence of independent technology, and the long computational time.
The “Mazu Wave” mode includes modules for grid generation, numerical calculation, post-processing and product production, and accuracy verification, providing a complete and comprehensive system. The mode can provide operational global and regional sea wave numerical forecasting products for the next seven days. The operational test results show that the “Mazu Wave” mode is efficient and reliable, with a fault rate below 1%. Compared with existing operational sea wave numerical forecasting modes, the computational efficiency is significantly improved, and the forecasting accuracy is notably enhanced, meeting the requirements for operational operation.
It is worth noting that during the period affected by Typhoon No. 3, the extremely strong typhoon “Goni,” China made its first use of the independently developed “Mazu Wave” mode for sea wave warning, providing important support for timely and accurate sea wave warnings. The successful application of this technology marks a new breakthrough in China’s marine environmental forecasting field, which is of great significance for ensuring maritime traffic safety, marine resource development, and the prevention of marine disasters.
