| Zusammenfassung |
| In this paper we present a multivariate regional test we developed for the
detection of trends in extreme rainfall, which takes into account the
spatial dependence between rainfall measurements with copula functions. The
test is based on four steps. It was applied to a set of 92 series of Annual
Daily Maxima (ADM) rainfall in the French Mediterranean area, sampled during
the 1949–2004 observation period. The results show a low significant trend,
concerning mainly the mountains area in the west part of the French
Mediterranean region. The position's parameters of the ADM rainfall
probability distribution functions present a low but significant increasing
trend of about 5% to 10%, the same increase as that observed in ADM
rainfall quantiles in the last 56 years. Further work is needed
to understand if this significative trend is related to the global climate
change or to the natural variability of Mediterranean climate. |
