Short summary

A new internal solitary wave (ISW) numerical model in the northern South China Sea (ISWNM-NSCS v2.0) improves ISW predictions by incorporating background currents and inhomogeneous stratifications. Additionally, viscosity and diffusivity coefficients are optimized to maintain stable stratifications, extending the forecasting period. Sensitivity experiments show that ISWNM-NSCS v2.0 significantly enhances predictions of various wave properties.
