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…
