Nonlinear interactions between the Amazon River basin and the Tropical North Atlantic at interannual timescales
Alejandro Builes-Jaramillo, Norbert Marwan, Germán Poveda +1
We study the physical processes involved in the potential influence of Amazon (AM) hydroclimatology over the Tropical North Atlantic (TNA) Sea Surface Temperatures (SST) at interan…
Network-based Approach and Climate Change Benefits for Forecasting the Amount of Indian Monsoon Rainfall
Jingfang Fan, Jun Meng, Josef Ludescher +5
The Indian summer monsoon rainfall (ISMR) has a decisive influence on India's agricultural output and economy. Extreme deviations from the normal seasonal amount of rainfall can ca…
Complexity based approach for El Nino magnitude forecasting before the "spring predictability barrier"
Jun Meng, Jingfang Fan, Josef Ludescher +5
The El Nino Southern Oscillation (ENSO) is one of the most prominent interannual climate phenomena. An early and reliable ENSO forecasting remains a crucial goal, due to its seriou…
Transitions between Metastable States in a Simplified Model for the Thermohaline Circulation under Random Fluctuations
Daniel Tesfay, Pingyuan Wei, Yayun Zheng +2
In this work, we study the impact of non-Gaussian alpha-stable Levy motion on transitions between metastable equilibrium states (or attractors) in a stochastic Stommel two-box mode…
Temporal organization of magnetospheric fluctuations unveiled by recurrence patterns in the Dst index
Reik V. Donner, Veronika Stolbova, Georgios Balasis +4
Magnetic storms constitute the most remarkable large-scale phenomena of nonlinear magnetospheric dynamics. Studying the dynamical organization of macroscopic variability in terms o…
Global teleconnectivity structures of the El Niño-Southern Oscillation and large volcanic eruptions -- An evolving network perspective
Tim Kittel, Catrin Ciemer, Nastaran Lotfi +4
Recent work has provided ample evidence that global climate dynamics at time-scales between multiple weeks and several years can be severely affected by the episodic occurrence of…
