“…The area is dominated by semi-arid and arid climates except for the northwestern part that is governed by a Mediterranean climate (Greenbaum et al, 2006). Mean annual precipitation shows a steep gradient from over 500 mm in the northwestern portion of the area to about 150 mm and even less than 50 mm in the northeastern and southern parts, respectively (Fig.…”

Abstract. Spatiotemporal patterns of rainfall are important characteristics that influence runoff generation and flashflood magnitude and require high-resolution measurements to be adequately represented. This need is further emphasized in arid climates, where rainfall is scarce and highly variable. In this study, 24 years of corrected and gaugeadjusted radar rainfall estimates are used to (i) identify the spatial structure and dynamics of convective rain cells in a dry climate region in the Eastern Mediterranean, (ii) to determine their climatology, and (iii) to understand their relation with the governing synoptic systems and with flashflood generation. Rain cells are extracted using a segmentation method and a tracking algorithm, and are clustered into three synoptic patterns according to atmospheric variables from the ERA-Interim reanalysis. On average, the cells are about 90 km 2 in size, move 13 m s −1 from west to east, and live for 18 min. The Cyprus low accounts for 30 % of the events, the low to the east of the study region for 44 %, and the Active Red Sea Trough for 26 %. The Active Red Sea Trough produces shorter rain events composed of rain cells with higher rain intensities, longer lifetime, smaller area, and lower velocities. The area of rain cells is positively correlated with topographic height. The number of cells is negatively correlated with the distance from the shoreline. Rain-cell intensity is negatively correlated with mean annual precipitation. Flash-flood-related events are dominated by rain cells of large size, low velocity, and long lifetime that move downstream with the main axis of the catchments. These results can be further used for stochastic simulations of convective rain storms and serve as input for hydrological models and for flash-flood nowcasting systems.

“…floods), or up to several years in the case of droughts. Clustering of extreme hydrological events has been related to climate variability (Rumsby and Macklin, 1994;Ely, 1997;Knox, 2000;Redmond et al, 2002), although land use changes have affected runoff generation at the catchment scale, particularly during the Middle Ages and the 19th Century (Greenbaum et al, 2006;Benito et al, 2010).…”

Mediterranean fluvial hydrology is characterised by decadal-to-multi-centennial length wet and dry episodes with abrupt transitions related to changes in atmospheric circulation. Since the mid-1990s site-based flood chronologies from slackwater deposits in bedrock rivers and regionally aggregated flood histories from alluvial deposits have developed increasingly higher resolution chronological frameworks, although regional coverage is still uneven. This paper analyses the spatial and temporal distribution of extreme Holocene hydrological events recorded in fluvial stratigraphy in the Iberian Peninsula (Spain and Portugal), southern France, southern Italy, Northern Africa (Morocco and Tunisia) and eastern Mediterranean (Greece, Crete, Turkey, Cyprus and Israel). This study constitutes the most comprehensive investigation of Holocene river flooding ever undertaken in the Mediterranean and is based on the analysis of 515 14 C and 53 OSL dates. It reveals that flood periods in different regions cluster into distinct time intervals, although region-wide flooding episodes can be identified at

The cosmogenic isotope 7Be (t1/2 = 53.3d) was measured in sediments collected from dust traps deployed in the Judean Desert which is part of the Dead Sea drainage basin. The results show that (a) the 7Be dry deposition flux in the Dead Sea region is 2.0 ± 0.6 × 104 atoms cm−2 y−1 during summer and winter and 5.3 ± 0.7 × 104 atoms cm−2 y−1 during fall; (b) the residence time of dust in the Dead Sea drainage basin is less than one year; (c) the recycled component of the cosmogenic isotope 10Be (t1/2 = 1.39 106y) in Judean desert dust is potentially small; and (d) the 7Be inventory (atoms cm−2) in dust settled in the drainage basin did not reach steady state between consecutive rare events of desert winter floods suggesting a short transport rate of fine detritus material from the marginal terraces into the Dead Sea. Provided 10Be behaves similarly (as implied by the common geochemistry and cosmogenic origin of 7Be and 10Be), we suggest 10Be in Lake Lisan (Pleistocene Dead Sea) detrital sediments as a potential proxy for paleo‐flood frequency and dust transport.
