| Zusammenfassung |
| Understanding extreme precipitation is very important
for Ethiopia, which is heavily dependent on low-productivity
rainfed agriculture but lacks structural and
non-structural water regulating and storage mechanisms.
There has been an increasing concern about whether there is an
increasing trend in extreme precipitation as the climate changes.
Existing analysis of this region has been descriptive,
without taking advantage of the advances in extreme value modeling.
After reviewing the statistical methodology on extremes,
this paper presents an analysis based on the generalized
extreme value modeling with daily time series of precipitation
records at Debre Markos in the Northwestern Highlands of Ethiopia.
We found no strong evidence to reject the null hypothesis
that there is no increasing trend in extreme precipitation
at this location. |
