摘要利用多重网格软件包mudpack对大气科学中不同领域的椭圆型偏微分方程组进行了简单有效的求解。计算结果表明，多重网格法比高斯消去法和固定网格松弛法等常用的数值方法更有效。相对于其他方法的效率，无论是在计算时间和存储需求方面，随着网格大小的快速增加。
Abstract Elliptic partial differential equations from different areas in the atmospheric sciences are easily and efficiently solved using the multigrid software package mudpack. It is shown that the multigrid method is more efficient than other commonly used methods, such as Gaussian elimination and fixed-grid relaxation. The efficiency relative to other methods, both in terms of computational time and storage requirement, increases rapidly with grid size.
