摘要：

根据平潭附近海域实际需求和地理区位特点，研发了三维温、盐、流高分辨率业务化数值预报系统，对该系统采用的模式、配置、预报结果验证和业务化运行等情况进行了详细介绍。该系统基于ROMS海流模式，采用正交曲线网格和网格嵌套技术；建立了包含数据预处理、温盐流预报和预报产品后处理等子程序的业务化数值预报系统。结果表明：模式预报产品具有较高精度，整个业务流程运行在30 min之内，系统运行稳定，达到业务化预报的要求。

Based on geographic and hydrodynamic characteristics of Pingtan coastal region of Fujian Province of China, an operational three-dimensional numerical system for sea temperature, salinity and current forecasting with high horizontal and vertical resolutions have been developed. This paper details the numerical model, configuration, results validation, and operational running. This forecasting system is based on ROMS model, by using orthotropic curvilinear grids and nested grid techniques. This system is composed of pre-processing data module, forecasting module, and forecasting production visualization module. The forecasting system has shown reasonable results by comparing with observational data, and the operational running time of the system is constrained in 30 min. The system is stable, and has reached the requirement and standard to become an operational forecasting system.
