The Fluctuation-Response relation in Geophysical Systems

(LV.pdf, 1229826 bytes)

Abstract:

We show how a general formulation of the Fluctuation-Response Relation
is able to describe in detail the connection between response properties
to external perturbations and spontaneous fluctuations in systems with
fast and slow variables.
Numerical computations on systems with many
characteristic times show the relevance of the above relation in
realistic cases.
