Irreversible Circulation of Fluctuation and Entropy Production Hiroyuki
Physical and chemical stochastic processes described by the master equation are investigated. The system-size expansion, called the Ω-expansion, transforms the master equation to the corresponding Fokker-Planck equation. In this paper, we examine the entropy production for both the master equation and the corresponding Fokker-Planck equation. For the master equation, the exact expression of the...

متن کاملIs a Shutdown of the Thermohaline Circulation Irreversible?
The thermohaline circulation (THC) in the North Atlantic plays a vital role in explaining past abrupt climate changes and in maintaining the current climate. Its remarkable nonlinear dynamics, first demonstrated by Stommel, has been supported by various types of climate models. This has led to severe concerns that global warming may shut down the THC irreversibly, with consequent catastrophic c...
متن کاملFluctuation relations and positivity of the entropy production in irreversible dynamical systems
We give a generalization of fluctuation identities and inequalities for the entropy production when the microscopic dynamics preserves the phase space volume but is not assumed to be dynamically reversible. We find that general first properties such as the strict positivity of the entropy production or the validity of an H−theorem are unaffected by the irreversibility of the dynamics. Fluctuati...
متن کاملAvailable potential energy and irreversible mixing in the meridional overturning circulation
The overturning circulation of the global oceans is examined from an energetics viewpoint. The general framework of Winters et al. (1995) for stratified turbulence is used, first to highlight the importance of available potential energy in facilitating the transfer of kinetic energy to the background potential energy (defined as the adiabatically-rearranged state with no motion). Next, it is sh...
