A new global marine environmental forecasting system will serve the public soon

Based on publicly accessible data, this project will carry out supplementary observations and experiments; conduct further studies on multi-scale ocean mixing processes; improve the marine physical parameterization scheme; improve the numerical grid, algorithm technology, parallel technology, and coupling technology; and develop a combined global high-resolution ocean circulation model, tidal model, ocean wave model and wave-tide-flow coupling model for operational forecasting.

This project will also develop a pressure-coordinate ocean numerical model, a coupled ocean-atmosphere model, and other new technology from China's own research and development for future operational applications.

These models will be implemented to establish a global high-resolution ocean prediction system, and forecast products will be released, including temperature, salinity, velocity, and ocean wave and tidal currents with a horizontal resolution of 10 km.

The accuracy of these products will reach an advanced international level. The system will clearly identify ocean mesoscale phenomena, with a forecasting validity time of five to seven days.

Thus far, a series of results have been obtained including multi-source ocean observation datasets, the setup of models, vertical mixing parameterization and its mechanism, amongst others.
