摘　　要：文中从两个独立的假定导出了距平模式,即:假定年周期气候态为控制实际气候系统演化方程组的解或假定反映年周期气候态的基态量远大于反映气候扰动态的扰动量。第一个假定放宽了导出距平模式的条件,而在第二个假定下距平模式在一定的近似程度下是成立的。另外笔者注意到:距平模式通过引入实际观测到的年周期态,相当于在非距平模中引入了年周期气候态的修正项。An anomaly model is derived under the two independent presuppositions that are the annual climate is the solution to the equations controlling the climate system evolvement and the basic quantity of annual climate is much Larger than the perturbation quantity of the annual climate disturbance. The first presupposition relaues the conditions of the anomaly model and in the second presupposition the anomaly model is approximately existent. In addition, we find that the observational annual climate used in the anomaly model corresponds to the modification of the annual climate used in the non-anomaly model.
