本文分析了一个零维气候模式的Fokker-Planck方程的时变特性，该模式表现出周期性，并受弱周期性外力的影响。通过分析发现了反应放大的条件。通过这种方式，建立了气候状态之间转换的可能性。地球轨道偏心率的10万年周期性与冰川循环有关，说明了这一结果。DOI：10.1111/j.2153-3490.1982.tb01786.x
The time-dependent properties of the Fokker–Planck equation corresponding to a zero-dimensional climate model, showing bistable behavior and subject to a weak external periodic forcing are analyzed. Conditions under which the response is amplified are found analytically. In this way the possibility of transitions between climatic states is established. The results are illustrated by the 100,000-yr periodicity of the eccentricity of the earth's orbit, in connection with glaciation cycles. DOI: 10.1111/j.2153-3490.1982.tb01786.x
