Reduced-order modeling of the upper tropical Pacific ocean model using proper orthogonal decomposition. (English) Zbl 1161.86002
The paper applies the proper orthogonal decomposition (POD) to reduced order modeling of a large-scale upper ocean circulation in the tropic Pacific domain. The authors construct different POD models with different choices of snapshots and different number of POD basis functions, compare the results from these different POD models with that of the original model, and finally conclude that the POD reduced modeling can be a powerful tool for various large-scale applications such as four-dimensional variational data assimilation.
