| description | For drought management and prediction, knowledge of causing factors
and socio-economic impacts of hydrological droughts is
crucial. Propagation of meteorological conditions in the hydrological
cycle results in different hydrological drought types that require
separate analysis. In addition to the existing hydrological drought
typology, we here define two new drought types related to snow and
ice. A <i>snowmelt drought</i> is a deficiency in the snowmelt
discharge peak in spring in snow-influenced basins and
a <i>glaciermelt drought</i> is a deficiency in the glaciermelt
discharge peak in summer in glacierised basins. In 21 catchments in
Austria and Norway we studied the meteorological conditions in the
seasons preceding and at the time of <i>snowmelt and glaciermelt
drought</i> events. <i>Snowmelt droughts</i> in Norway were mainly
controlled by below-average winter precipitation, while in Austria
both temperature and precipitation played a role. For
<i>glaciermelt droughts</i>, the effect of below-average summer air temperature
was dominant, both in Austria and Norway. Subsequently, we
investigated the impacts of temperature-related drought types
(i.e. <i>snowmelt and glaciermelt drought</i>, but also <i>cold
and warm snow season drought</i> and <i>rain-to-snow-season
drought</i>). In historical archives and drought databases for the US and
Europe many impacts were found that can be attributed to these
temperature-related hydrological drought types, mainly in the
agriculture and electricity production (hydropower) sectors. However, drawing
conclusions on the frequency of occurrence of different drought types
from reported impacts is difficult, mainly because of reporting biases
and the inevitably limited spatial and temporal scales of the
information. Finally, this study shows that complete integration of quantitative
analysis of causing factors and qualitative analysis of impacts of
temperature-related droughts is not yet possible. Analysis of selected events,
however, points out that it can be a promising research area if more data on
drought impacts become available. |
