| 内容記述 | A Fourier filtering is examined in a polar ocean model based on the vorticity equation. A circular basin centered at the North Pole is considered. Flows are driven by an inflow and an outflow prescribed at the circumference. Two peninsulas are provided for examination of the filtering effect. In a slip boundary case, longitudinal distribution of the predicted vorticity is expanded in sine series and high wavenumber components are eliminated. The solution obtained with the filtering agrees well with that obtained without filterings. In a viscous boundary case, the vorticity is expanded in cosine series and high wavenumber components are eliminated. The filtering does not affect the general flow pattern, although it slightly affects the local vorticity field near irregular coastal boundaries. | |||||
