Nonlinear forced change and nonergodicity: The case of ENSO-Indian monsoon and global precipitation teleconnections
Tamás Bódai, Gábor Drótos, Kyung-Ja Ha +3
We study the forced response of the teleconnection between the El Nino-Southern Oscillation (ENSO) and global precipitation in general and the Indian summer monsoon (IM) in particu…
Rough basin boundaries in high dimension: Can we classify them experimentally?
Tamas Bodai, Valerio Lucarini
We show that a known condition for having rough basin boundaries in bistable 2D maps holds for high-dimensional bistable systems that possess a unique nonattracting chaotic set emb…
Global Stability Properties of the Climate: Melancholia States, Invariant Measures, and Phase Transitions
Valerio Lucarini, Tamas Bodai
For a wide range of values of the incoming solar radiation, the Earth features at least two attracting states, which correspond to competing climates. The warm climate is analogous…
Effects of Stochastic Parametrization on Extreme Value Statistics
Guannan Hu, Tamás Bódai, Valerio Lucarini
Extreme geophysical events are of crucial relevance to our daily life: they threaten human lives and cause property damage. To assess the risk and reduce losses, we need to model a…
An efficient algorithm to estimate the potential barrier height from noise-induced escape time data
Tamás Bódai
It is a common phenomenon in nature and technology that a system under perturbations exits a regime of its usual dynamics. Often it is possible to define a potential function where…
Transitions across Melancholia States in a Climate Model: Reconciling the Deterministic and Stochastic Points of View
Valerio Lucarini, Tamas Bodai
The Earth is well-known to be, in the current astronomical configuration, in a regime where two asymptotic states can be realised. The warm state we live in is in competition with…
Can we use linear response theory to assess geoengineering strategies?
Tamas Bodai, Valerio Lucarini, Frank Lunkeit
Geoengineering can control only some climatic variables but not others, resulting in side-effects. We investigate in an intermediate-complexity climate model the applicability of l…
Reconsidering the relationship of the El Niño--Southern Oscillation and the Indian monsoon using ensembles in Earth system models
Mátyás Herein, Gábor Drótos, Tamás Bódai +2
We study the relationship between the El Niño--Southern Oscillation (ENSO) and the Indian summer monsoon in ensemble simulations from state-of-the-art climate models, the Max Planc…
Convergence of extreme value statistics in a two-layer quasi-geostrophic atmospheric model
Vera Melinda Galfi, Tamas Bodai, Valerio Lucarini
We search for the signature of universal properties of extreme events, theoretically predicted for Axiom A flows, in a chaotic and high dimensional dynamical system by studying the…
Edge States in the Climate System: Exploring Global Instabilities and Critical Transitions
Valerio Lucarini, Tamas Bodai
Multistability is a ubiquitous feature in systems of geophysical relevance and provides key challenges for our ability to predict a system's response to perturbations. Near critica…
Predictability of threshold exceedances in dynamical systems
Tamas Bodai
In a low-order model of the general circulation of the atmosphere we examine the predictability of threshold exceedance events of certain observables. The likelihood of such binary…
Global instability in the Ghil-Sellers model
Tamas Bodai, Valerio Lucarini, Frank Lunkeit +1
The Ghil-Sellers energy balance model of Earth's climate, features -- for a considerable range of the solar intensity -- two stable climate states (a warm and a cold snowball Earth…
Stochastic perturbations in open chaotic systems: random versus noisy maps
Tamas Bodai, Eduardo G. Altmann, Antonio Endler
We investigate the effects of random perturbations on fully chaotic open systems. Perturbations can be applied to each trajectory independently (white noise) or simultaneously to a…
