Equations for the Layered Model The ocean model is the multilayered and nonlinear quasigeostrophic model on an f plane [see =-=Pedlosky, 1987-=-] and has been applied and further discussed by Haugan et al. [1991] and Evensen [1992, 1993]. It describes conservation of potential vorticity i l in each layer on an f plane. The mean layer thicknes... |

The divergence term on the right-hand side is zero for a conservative system like the QG model [see =-=Salmon et al., 1976-=-]. Equation (16) then becomes Liouville's theorem, which states that the density of the ensemble is conserved with the motion along a path in phase space. Consider the volume element dD in phase space... |

This represents a property of conservative systems where the probability density is conserved with the motion in phase space [see =-=Gleeson, 1970-=-]. The diffusion term causes the system to lose energy; that is, the variance is decreasing. This leads to increasing probability in (18), which is equivalent to increasing predictability.
