This «statistical coherence» can be regarded as a kind of organization of
a complicated dynamical system, and identifying its statistically stable characteristics is similar to the notion of coherence understood as self - organization of multicomponent systems that results from chaotic interactions of their elements (see, e.g., [1]-RRB-.»
There may be reason to strongly suspect that in any sufficiently
complicated dynamical system model (such as climate) with stochastic parameters (e.g., exactly when and where a lightning strike starts a major wildfire or a major submarine earthquake perturbs ocean circulation in a region or a major volcanic eruption introduces stratospheric aerosols), it is almost certain that any given run of the model will have periods of significant deviation from the mean of multiple runs.
