Seasonal evolution of the Arctic sea ice thickness distribution
Srikanth Toppaladoddi, Woosok Moon, John S. Wettlaufer
The Thorndike et al., (\emph{J. Geophys. Res.} {\bf 80} 4501, 1975) theory of the ice thickness distribution, , treats the dynamic and thermodynamic aggregate properties of t…
The Thermodynamic Cost of Erasing Information in Finite-time
L. T. Giorgini, R. Eichhorn, M. Das +2
The Landauer principle sets a fundamental thermodynamic constraint on the minimum amount of heat that must be dissipated to erase one logical bit of information through a quasi-sta…
Asymptotic interpretation of the Miles mechanism of wind-wave instability
A. F. Bonfils, Dhrubaditya Mitra, W. Moon +1
When wind blows over water, ripples are generated on the water surface. These ripples can be regarded as perturbations of the wind field, which is modelled as a parallel inviscid f…
Analytical solution of stochastic resonance in the nonadiabatic regime
W. Moon, L. T. Giorgini, J. S. Wettlaufer
We generalize stochastic resonance to the nonadiabatic limit by treating the double-well potential using two quadratic potentials. We use a singular perturbation method to determin…
Eddy memory as an explanation of intra-seasonal periodic behavior in baroclinic eddies
Woosok Moon, Georgy E. Manucharyan, Henk A. Dijkstra
The baroclinic annular mode (BAM) is a leading-order mode of the eddy-kinetic energy in the Southern Hemisphere exhibiting. oscillatory behavior at intra-seasonal time scales. The…
A Non-Gaussian Stochastic Model for the El Niño Southern Oscillation
L. T. Giorgini, W. Moon, N. Chen +1
A non-autonomous stochastic dynamical model approach is developed to describe the seasonal to interannual variability of the El Niño-Southern Oscillation (ENSO). We determine the m…

J. Y-K. Cho, H. Th. Thrastarson, T. T. Koskinen +4
We review the recent progress in understanding the jet structures on exoplanets as well as on and inside the Sun. The emphasis is on the more robust aspects of observation and nume…
Analytical Survival Analysis of the Ornstein-Uhlenbeck Process
L. T. Giorgini, W. Moon, J. S. Wettlaufer
We use asymptotic methods from the theory of differential equations to obtain an analytical expression for the survival probability of an Ornstein-Uhlenbeck process with a potentia…
Coupling functions in climate
Woosok Moon, John S. Wettlaufer
We examine how coupling functions in the theory of dynamical systems provide a quantitative window into climate dynamics. Previously we have shown that a one-dimensional periodic n…

Soon Hoe Lim, Ludovico Theo Giorgini, Woosok Moon +1
We study the problem of predicting rare critical transition events for a class of slow-fast nonlinear dynamical systems. The state of the system of interest is described by a slow…
Nonadiabatic escape and stochastic resonance
W. Moon, N. J. Balmforth, J. S. Wettlaufer
We analyze the fluctuation-driven escape of particles from a metastable state under the influence of a weak periodic force. We develop an asymptotic method to solve the appropriate…
Precursors to Rare Events in Stochastic Resonance
L. T. Giorgini, S. H. Lim, W. Moon +1
In stochastic resonance, a periodically forced Brownian particle in a double-well potential jumps between minima at rare increments, the prediction of which poses a major theoretic…
An intrinsic pink-noise multi-decadal global climate dynamics mode
W. Moon, S. Agarwal, J. S. Wettlaufer
Understanding multi-decadal variability is an essential goal of climate dynamics. For example, the recent phenomenon referred to as the "global warming hiatus" may reflect a coupli…
