The governing equations of the model based on water vapor heat exchange include: two-dimensional shallow water governing equations, water temperature convection and diffusion, ice formation in water, surface flow ice, ice sheet growth and ablation, etc. the partial differential equations are discretized by finite volume (FVM) integration on unstructured grids.
