| Zusammenfassung |
| Since the mid-1990s the majority of Victoria, Australia, has experienced
severe drought conditions (i.e. the "Big Dry") characterized by streamflow
that is the lowest in approximately 80 years of record. While decreases in
annual and seasonal rainfall totals have also been observed, this alone does
not seem to explain the observed reduction in flow. In this study, we
investigate the large-scale climate drivers for Victoria and demonstrate how
these modulate the regional scale synoptic patterns, which in turn alter the
way seasonal rainfall totals are compiled and the amount of runoff per unit
rainfall that is produced. The hydrological implications are significant and
illustrate the need for robust hydrological modelling, that takes into
account insights into physical mechanisms that drive regional
hydroclimatology, in order to properly understand and quantify the impacts
of climate change (natural and/or anthropogenic) on water resources. |
