摘要：
The response of the nonlinear oscillatory system to an insignificant external disturbance has been considered as applied to the effect of solar activity on climatic processes. Based on a simplified model, it has been indicated that the response of a nonlinear oscillator to a weak disturbing impact can be substantial. The oscillator fluctuation spectrum can decrease under the action of a disturbing factor. This means that the effect of an even weak solar or cosmophysical signal to the Earth’s climatic system can lead to significant climate variations if this system is nonlinear. However, it will be rather difficult to identify the solar—climatic nature of these variations because a linear relation between the cause and response is absent.
