Eddy stirring in the Southern Ocean

[1] There is an ongoing debate concerning the distribution of eddy stirring across the Antarctic Circumpolar Current (ACC) and the nature of its controlling processes. The problem is addressed here by estimating the isentropic eddy diffusivity from a collection of hydrographic and altimetric observations, analyzed in a mixing length theoretical framework. It is shown that, typically, is suppres...

Stirring in the global surface ocean

[1] Global variations of stirring in the surface ocean are quantified using finite-time Lyapunov exponents (FTLEs) calculated from currents derived from satellite altimetry. It is shown that the stirring is highly non-uniform, and the probability distribution functions (PDFs) of the FTLEs are broad, asymmetric, and have long high-stretch tails. The characteristics of the PDFs vary with mesoscal...

How the Nonextensivity Parameter Affects Energy Fluctuations

In this article, the effect of the nonextensivity parameter on the energy fluctuations of nonextensive systems is studied in two different versions of the Tsallis statistical mechanics. Once a general expression has been reported for the energy fluctuations in the second version (Tsallis work in 1988), the energy fluctuations of an ideal gas and a harmonic oscillator are studied in the second a...
