Query: Causal mechanism of extreme river discharges in the upper Danube basin
  network   Extreme hydrological events in the Danube river basin may severely impact
human populations, aquatic organisms, and economic activity. One often
characterizes the joint structure of the extreme events using the theory of
multivariate and spatial extremes and its asymptotically justified models.
There is interest however in cascading extreme events and whether one event
causes another. In this paper, we argue that an improved understanding of the
mechanism underlying severe events is achieved by combining extreme value
modelling and causal discovery. We construct a causal inference method relying
on the notion of the Kolmogorov complexity of extreme conditional quantiles.
Tail quantities are derived using multivariate extreme value models and
causal-induced asymmetries in the data are explored through the minimum
description length principle. Our CausEV, for Causality for Extreme Values,
approach uncovers causal relations between summer extreme river discharges in
the upper Danube basin and finds significant causal links between the Danube
and its Alpine tributary Lech.
