Precursor signals for bifurcation-induced critical transitions have recently gained interest
across many research fields. Common indicators, including variance and autocorrelation …

Many models and real complex systems possess critical thresholds at which the systems
shift dramatically from one sate to another. The discovery of early-warnings in the vicinity of …

Local bifurcations of stationary points and limit cycles have successfully been characterized
in terms of the critical exponents of these solutions. Lyapunov exponents and their …

We address the problem of defining early warning indicators of financial crises. To this
purpose, we fit the relevant time series through a class of linear models, known as auto …

Among the properties that are common to complex systems, the presence of critical
thresholds in the dynamics of the system is one of the most important. Recently, there has …

Detecting Regime Transitions of the Nocturnal and Polar Near-Surface Temperature
Inversion in: Journal of the Atmospheric Sciences Volume 77 Issue 8 (2020) Jump to …

The atmospheric stable boundary layer (SBL) is observed to display multiple regimes of
stratification, flow, and turbulence. Transitions between weakly stable regimes of sustained …

A statistical indicator for dynamic stability, known as the Υ indicator, is used to gauge the
stability and, hence, detect approaching tipping points of simulation data from a reduced five …

The modifications of atmospheric circulation induced by anthropogenic effects are difficult to
capture because wind fields feature a complex spectrum where the signal of large-scale …

We suggest an approach to probing intermittency corrections to the Kolmogorov law in
turbulent flows based on the autoregressive moving-average modeling of turbulent time …
