Time-Dependent Solutions to the Fokker-Planck Equation of Maximum Reduced Air-Sea Coupling Climate Model
The time-dependent solution of reduced air-sea coupling stochastic-dynamic model is accurately obtained by using the Fokker-Planck equation and the quantum mechanical method. The analysis of the timedependent solution suggests that when the climate system is in the ground state, the behavior of the system appears to be a Brownian movement, thus reasoning the foothold of Hasselmann's stochastic climatic model;when the system is in the first excitation state, the motion of the system exhibits a form of time-decaying,or under certain condition a periodic oscillation with the main period being 2.3 yr. At last, the results are used to discuss the impact of the doubling of carbon dioxide on climate.
