Application of Coupled Harmonic Oscillator model to Solar Activity and El Ni\~no Phenomena

Abstract

The solar activity provides an important impact not only on the intensity of cosmic rays but also on the earth environment. In this paper, a coupled oscillator model is proposed to explain the solar activity. By this model the 89 year Gleissberg cycle can be naturally reduced. Furthermore as an application of the coupled oscillator model we try to apply it to the El Nino-La Nina phenomena (ENSO). The 22 year oscillation of the Pacific Ocean is naturally explained. Finally we search a possible substance of the coupled oscillators in actual solar activities.
