Abstract: Through examples, the mechanism of the generation of the aliasing error associated with upwind compact difference schemes and spectral method is studied and compared. The comparison shows the upwind compact difference schemes have some advantages in treating the aliasing error.

Key words: aliasing error, upwind compact difference schemes, spectral method
