摘要/Abstract

摘要： 在计算域面积为常数的约束下,给出了在单波情况下几种不同精度的平流方程的"最优垂直网格距",以及在极限情况下的"协调垂直网格距"的表达式,还推导了在多波情况下的相应的表达式。

Abstract: Subject to constant computational area, two expressions of optimal vertical gridlength with different accuracy and an expression of consistent vertical gridlength were presented in the case of a single wave. And the corresponding expression of consistent vertical gridlength in the multiwave case was derived-

Key words: consistency vertical, horizontal resolution advection equation
