Changing climatic conditions have led to a significant increase in the magnitude and frequency of extreme rainfall events in the Central Andes of South America. These events are spatially extensive and often result in substantial natural hazards for population, economy and ecology. Here we develop a general framework to predict extreme events by introducing the concept of network divergence on directed networks derived from a non-linear synchronization measure. We apply our method to real-time… 

Propagation of Strong Rainfall Events from Southeastern South America to the Central Andes

AbstractBased on high-spatiotemporal-resolution data, the authors perform a climatological study of strong rainfall events propagating from southeastern South America to the eastern slopes of the

A network-based comparative study of extreme tropical and frontal storm rainfall over Japan

Frequent and intense rainfall events demand innovative techniques to better predict the extreme rainfall dynamics. This task requires essentially the assessment of the basic types of atmospheric

Network-based forecasting of climate phenomena

It is argued that network-based approaches can gainfully complement numerical modeling and highlight several cases where the network approach substantially improved the prediction of high-impact phenomena.

Predicting climate extremes - a complex network approach

Regional decadal predictions have emerged in the past few years as a research field with high application potential, especially for extremes like heat and drought periods. However, up to now the

Large-scale climate patterns and precipitation in an arid endorheic region: linkage and underlying mechanism

The interactions between a range of large-scale climate oscillations and their quantitative links with precipitation are basic prerequisites to understand the hydrologic cycle. Restricted by the

Temporal evolution of the spatial covariability of rainfall in South America

The climate of South America exhibits pronounced differences between rainy and dry seasons, associated with specific synoptic features such as the establishment of the South Atlantic convergence

Spatiotemporal characteristics and synchronization of extreme rainfall in South America with focus on the Andes Mountain range

The South American Andes are frequently exposed to intense rainfall events with varying moisture sources and precipitation-forming processes. In this study, we assess the spatiotemporal

Spatio-temporal synchronization of heavy rainfall events triggered by atmospheric rivers in North America

. Atmospheric rivers (ARs) are filaments of extensive water vapor transport in the lower troposphere, that play a crucial role in the distribution of water, but can also cause natural and economical
