Fokker planck analysis linear energy shift

In statistical mechanics, the Fokker–Planck equation is a partial differential equation that describes the time evolution of the probability density function of the velocity of a particle under the influence of drag forces and random forces, as in Brownian motion. The equation can be generalized to other observables as well. It is named after Adriaan Fokker and Max Planck, who described it in 1914 and 1917. It is also kn… WebFor instance, Zheng et al. [28], based on the solution of the nonlocal Fokker–Planck equation, investigated the maximum likelihood climate change of an energy balance system under the extreme climate events, and found that the cold climate state suddenly shifts to the warm climate state owing to the presence of noisy fluctuation.
