“…Areas subject to high hydrological pressure present a high risk of significant material and human damage [1]. At the international level, hydrological hazards occur in any season, whether during heavy snow, the rapid melting of snow in the spring that generates rapid floods, or heavy precipitation in May-July in areas of central and eastern Europe [2]. Romania is not an exception.…”

“…As highlighted by Azari et al [2], it has several important implications for soil resources that are reflected in overall variations in the rainfall amount, intensity, spatial-temporal distribution, and increment in extreme precipitation events. The most direct effects of climate change on soil erosion are changes in rainfall erosivity due to changes in rainfall intensity [3] and the occurrence of extreme precipitation [4][5][6].…”

Estimation of rainfall erosivity (RE) and erosivity density (ED) is essential for understanding the complex relationships between hydrological and soil erosion processes. The main objective of this study is to assess the spatial–temporal trends and variability of the RE and ED in the central and southern Pannonian Basin by using station observations and gridded datasets. To assess RE and ED, precipitation data for 14 meteorological stations, 225 grid points. and an erosion model consisting of daily, monthly, seasonal, and annual rainfall for the period of 1961–2014 were used. Annual RE and ED based on station data match spatially variable patterns of precipitation, with higher values in the southwest (2100 MJ·mm·ha−1·h−1) and southeast (1650 MJ·mm·ha−1·h−1) of the study area, but minimal values in the northern part (700 MJ·mm·ha−1·h−1). On the other hand, gridded datasets display more detailed RE and ED spatial–temporal variability, with the values ranging from 250 to 2800 MJ·mm·ha−1·h−1. The identified trends are showing increasing values of RE (ranging between 0.20 and 21.17 MJ·mm·ha−1·h−1) and ED (ranging between 0.01 and 0.03 MJ·ha−1·h−1) at the annual level. This tendency is also observed for autumn RE (from 5.55 to 0.37 MJ·mm·ha−1·h−1) and ED (from 0.05 to 0.01 MJ·ha−1·h−1), as for spring RE (from 1.00 to 0.01 MJ·mm·ha−1·h−1) and ED (from 0.04 to 0.01 MJ·ha−1·h−1), due to the influence of the large-scale processes of climate variability, with North Atlantic Oscillation (NAO) being the most prominent. These increases may cause a transition to a higher erosive class in the future, thus raising concerns about this type of hydro-meteorological hazard in this part of the Pannonian Basin. The present analysis identifies seasons and places of greatest erosion risk, which is the starting point for implementing suitable mitigation measures at local to regional scales.

“…Extreme flooding is an important topic for climate research, with numerous studies concerning the various properties of extreme precipitation events, such as origin, development, trends and recurrence (Pendergrass et al, 2015;Tandon et al, 2018;Hamouda & Pasquero, 2021;Gimeno et al, 2022). An important flood producing process in the central European region is known as Vb-cyclone event.…”

Summer extreme flooding in Central Europe is often associated with Vb-cyclones which travel through the Mediterranean, then northwards east of the Alps towards Central Europe. Extreme convective precipitation intensities scale with the Clausius-Clapeyron relation under global warming. This study quantifies the importance of convective precipitation during Vb-events in present and in warmer climate by simulating selected Vb-events with convection-permitting grid-spacing. A simple convective precipitation diagnostic is compared against Lagrangian convective cell tracking. The simple method shows skill identifying convective precipitation in coarser simulations with parameterized convection. On average, 30\% of precipitation is classified as convective in reanalysis and historical EC-Earth3 driven simulations. This fraction increases to 52\% in a warmer climate under SSP5-8.5 scenario. The increase is explained by a frequency increase of the convectively active cut-off low-pressure systems and a doubling of the convective fraction in the less active trough-like Vb-cyclones, suggesting amplified flood risk in a warmer climate.
