| Zusammenfassung |
| From the point of view of multisite stochastic daily rainfall modelling,
there are two new ideas introduced in this paper. The first is the use of
asymmetrical copulas to model the spatial interdependence structure of the
rainfall amounts together with the rainfall occurrences in one relationship.
The second is in the evaluation of the (necessary but often ignored)
congregating behaviour of the higher values of simulated rainfall; this
evaluation is performed by calculating the entropy of the observations at all
the near equilateral triangles that can be formed from the sequences at the
gauge sites, as a function of their mutual separation distance. It turns out
that the model captures the qualities desired and offers a fresh approach to
a relatively mature problem in hydrometeorology. |
