Abstract:

A study is made of different techniques of assuring the long term numerical stability of a one-layer global primitive equation model which uses the pseudospectral technique for the evaluation of horizontal derivatives. It is found that numerical filtering is much more suitable than the use of a linear viscosity term both from the point of view of the stability achieved and the cost of the computation. Author
