dc.description.abstract | Flash droughts are defined as fast and intense dryings of the land system. In
these episodes, declines in precipitation deficits are often accompanied by rapid intensifications
of evaporative demand, leading to sharp soil moisture decreases and
noticeable agricultural and environmental impacts. This research presents a straightforward
framework for global historical characterization of precipitation-deficit-related
flash droughts, examining the extent to which this type of hazard can be described
using only pentad rainfall data. The Drought Exceedance Probability Index
was applied to global gridded high-resolution rainfall data for 1979 - 2020. Sharp upsurges
in the pentad index series were detected and counted to analyze the occurrence
of precipitation-deficit flash droughts. The precipitation characteristics associated to
flash drought incidence were explored to learn if some rainfall regimes or times of
the year are more prone to the phenomenon, which could help societies become more
prepared for the risk. It was observed that climates with marked inter-annual and
intra-annual rainfall variability record more flash droughts, especially when that variability
is significant during the local wet seasons. This is the case of regions with
erratic rainfall generation mechanisms such as Mediterranean climates or monsoon
climates. The episodes mainly occur during what is expected to be the humid time
of the year, when they can produce greater impact. The methodology used was able
to detect the most intense events described in previous studies that used variables associated
to soil moisture dryness, confirming the role of acute precipitation deficits
in triggering them. | es |
