An observed nonlinear dynamics is observable if the mapping from initial condition to output trajectory is one to one. The standard tool for checking observability is the observability rank conditionâ€¦ (More)

In this paper we develop analytical and numerical methods for finding special hyperbolic trajectories that govern geometry of Lagrangian structures in time-dependent vector fields. The vector fieldsâ€¦ (More)

This review presents a general theory of financial crashes and of stock market instabilities that his co-workers and the author have developed over the past seven years. We start by discussing theâ€¦ (More)

In Ensemble Kalman Filter data assimilation, localization modifies the error covariance matrices to suppress the influence of distant observations, removing spurious long distance correlations. Inâ€¦ (More)

A new method for directly assimilating Lagrangian tracer observations for flow state estimation is presented. It is developed in the context of point vortex systems. With tracer advection equationsâ€¦ (More)

Multiple equilibria as well as periodic and aperiodic solution regimes are obtained in a barotropic model of the midlatitude oceanâ€™s double-gyre circulation. The model circulation is driven by aâ€¦ (More)

We present a simple two-dimensional dynamical system where two nonlinear terms, exerting respectively positive feedback and reversal, compete to create a singularity in finite time decorated byâ€¦ (More)

Planetary flows--atmospheric and oceanic--are approximately two-dimensional and dominated by coherent concentrations of vorticity. Data assimilation attempts to determine optimally the current stateâ€¦ (More)

An analytic radiative-equilibrium model is formulated where both shortand longwave radiation are treated as two-stream (downand upward) fluxes. An equilibrium state is defined in the model by theâ€¦ (More)
