Abstract

The behaviour of the truncation errors in the numerical prediction using grid points, is discussed taking into account the scale of the perturbations.
When we forecast by the ordinary numerical prediction method the path of the relatively small cyclone such as the typhoon, the velocity of the center is known to become smaller than the observed value. We conclude that this fact can be explained by the behaviour of the truncation errors.
