Query: Features of the Earth's seasonal hydroclimate: Characterizations and
  comparisons across the Koppen-Geiger climates and across continents   Detailed feature investigations and comparisons across climates, continents
and time series types can progress our understanding and modelling ability of
the Earth's hydroclimate and its dynamics. As a step towards these important
directions, we here propose and extensively apply a multifaceted and
engineering-friendly methodological framework for the thorough characterization
of seasonal hydroclimatic dependence, variability and change at the global
scale. We apply this framework using over 13 000 quarterly temperature,
precipitation and river flow time series. In these time series, the seasonal
hydroclimatic behaviour is represented by 3-month means of earth-observed
variables. In our analyses, we also adopt the well-established Koppen-Geiger
climate classification system and define continental-scale regions with large
or medium density of observational stations. In this context, we provide in
parallel seasonal hydroclimatic feature summaries and comparisons in terms of
autocorrelation, seasonality, temporal variation, entropy, long-range
dependence and trends. We find notable differences to characterize the
magnitudes of most of these features across the various Koppen-Geiger climate
classes, as well as between several continental-scale geographical regions. We,
therefore, deem that the consideration of the comparative summaries could be
more beneficial in water resources engineering contexts than the also provided
global summaries. Lastly, we apply explainable machine learning to compare the
investigated features with respect to how informative they are in explaining
and predicting either the main Koppen-Geiger climate or the continental-scale
region, with the entropy, long-range dependence and trend features being
(roughly) found to be less informative than the remaining ones at the seasonal
time scale.
