准地转正压模式中的多重网格方法及对比

A MULTIGRID METHOD FOR QAUST GEOSTROPHIC BAROTROPIC MODEL AND CONTRAST

摘要: 介绍了多网格(简称MG)方法和完全多网格(简称FMG)方法,构造了数值天气预报准地转正压模式的计算方案,并对计算结果进行了分析对比.

Abstract: A geometry multigrid method was intreduced to solve a numerical forecast model probelm and the result was comparied with those of SOR and ADI.Numerical experiments demonstrated that MG method is obriously superior to the others.
