摘　　要：将非线性迭代时间积分方案用于大气环流模式 IAP AGCM-II中, 并用 Rossby-Hauwitz波进行了检验, 结果表明, 该方案能长期稳定的积分。此外, 还将采用该方案的模式(其中物理过程不变)和原 IAP AGCM-II模式作了模拟结果的比较, 以考察其效果; 发现采用该方案模式对降水尤其是东亚地区降水的模拟能力较原模式有所提高。The non-linear iteration time integralschemeis used in the dynamical framework of originalIAP AGCM-II modeland it is verifiedby Rossby-Hauwitzwave. The results show that the schemecan carry out long integration time with well stability.In order to further test itssimulation ability, two three year-long integral simulations of the model have been conduted, in which one is with the non-linear iteration time integral scheme;but the other is without. The simulations show that the model with the schemehas the better results of simulating precipitation, especially in East Asia region.
