2022年东南亚三维温盐流预报产品数据集

基于大气模式WRF和海洋模式POM，构建南海区域的海气耦合模式，模式范围覆盖0°N to 30°N 和 97°E to 135°E，包括部分西太平洋和整个南海。模式海底地形资料取自Gebco (General Bathymetric Chart of the Ocean)的30秒经纬网格资料并根据调查资料进行调整，模式最小水深取10米，最大水深取5500米；由1/6°准全球HYCOM预报结果作为侧边界。预报系统每天运行4次，即00:00、06:00、12:00和18:00（世界时），预报时效为120小时，预报要素包括了海表高度、温度、盐度、流场等。产品的平均水平分辨率为4分（约7.2km），时间分辨率为1小时，能够分辨南海主要动力过程。Based on the atmospheric model WRF and the oceanic model POM, an air-sea coupled model for the South China Sea region was developed. The model domain covers 0°N to 30°N and 97°E to 135°E, including partial areas of the western Pacific and the entire South China Sea. The seabed topography data for the model is sourced from the 30-arcsecond grid dataset of GEBCO (General Bathymetric Chart of the Ocean) and adjusted using in-situ survey data. The minimum and maximum water depths configured for the model are set to 10 meters and 5500 meters, respectively. Lateral boundary conditions are derived from 1/6° quasi-global HYCOM forecast results. The forecast system operates four times daily at 00:00, 06:00, 12:00, and 18:00 UTC, with a forecast lead time of 120 hours. The forecasted variables include sea surface height, water temperature, salinity, and current field, among others. The products have an average horizontal resolution of 4 arcminutes (approximately 7.2 km) and a temporal resolution of 1 hour, which is capable of resolving major dynamic processes in the South China Sea.
