| مستخلص: |
A method of diabatic initialization is described in which a nonrecursive digital filter is applied to both the backward (adiabatic) and forward (diabatic) steps. It has clear advantages over previously proposed schemes: the initialization requires significantly less computation time and the resulting changes in the analyzed fields are consistently smaller. Despite these smaller increments, the suppression of spurious high-frequency noise is at least as effective as for the earlier schemes. [ABSTRACT FROM AUTHOR] |
