On the computational noise of finite-difference schemes used in ocean models

Abstract

100 km) ocean model. For fine-scale resolution (<50 km), as in mesoscale ocean eddy models, it is shown that the C-scheme (in which the zonal velocity is carried at points to the east and west of the point of a rectangular grid where the height is carried, with the meridional velocity carried to the north and south of the height point) can be free of noise for the gravest mode (as in a two-layer model).>
