Abstract
During the 20th century, the intensity and frequency of extreme events (i.e., storms and floods) have significantly changed due to human-induced climate change. Recently, it has been recognized that regions in Egypt have become more vulnerable to extreme rainfall events which lead in some cases to severe flash floods. In this work, the variability of annual rainfall characteristics in Egypt was investigated based on a detailed statistical analysis of historical rainfall records of 31 stations. The parametric test (Pearson) and the non-parametric tests (Mann-Kendall and Spearman's Rho) were applied on four precipitation indices: Annual Maximum Precipitation (AMP), Annual Total Precipitation (ATP), Annual Rainy Days (ARD), and Simple Daily Intensity Index (SDII). The results showed that about 30% of the analyzed stations exhibited either decreasing or increasing significant trends, where no special patterns of trends were found.
