| 摘 要： | 利用NCAR的CCSM 2（community climate system model）气候系统模式分析研究插值方案对系统积分稳定性的影响。理想试验结果表明守恒插值的稳定性要好于双线性插值。但在数值试验中,由于海—气之间复杂的相互作用,使得采用两种不同插值方案计算得到的海—气界面通量的差异远小于理想试验。长期数值积分试验表明,采用守恒插值方案仅在模式系统积分的初期阶段有利于保持物理量守恒,对于模式系统的长期积分稳定性的影响,两种方案基本相同。

| Abstract: | In this paper,the influence of different interpolation methods on the stability of climate system model NCAR CCSM2 has been studied.The results of idealized experiment show that the stability of the conservative interpolation method is better than that of the bilinear one.While the air-sea interface flux calculated by two kinds of interpolation methods is far less than that obtained by the idealized experiment because of the complicated air-sea interaction.The long-term numerical integration experiments poi... |
