Summary: The study demonstrates that under climate change, hourly precipitation extremes and storm depths are expected to intensify in the US, with what is now a 20-year rainfall becoming a 7-year rainfall on average for approximately 75% of gridpoints. This intensification is mainly characterized by an increase in rainfall tail heaviness, with statistically significant changes in the seasonality and duration of rainfall extremes observed over about 95% of the domain.

Summary: This study focuses on how rainfall mechanisms and catchment characteristics influence the relationship between rainfall and flood probabilities. Regional differences in rainfall and runoff behaviors were observed, with wet catchments showing higher elasticities compared to dry catchments. Overall, catchment characteristics were found to be the dominant control on flood frequency patterns.

Summary: Assessing the relationship between intensity, duration, and frequency of extreme precipitation is crucial for water management system design. By using a duration-dependent formulation of the GEV distribution, a flexible model is developed to describe IDF relations over a wide range of durations.

Summary: This study analysed data from 82 rainfall simulations and found that SOC mitigated soil loss in locations with <14% slope inclination. However, in locations with >14% slope inclination, soil loss was driven by preferential erosion of fine-grained particles. The study also revealed that low soil loss was usually associated with high SOC enrichment, indicating that preferential erosion of SOC mainly occurred in soils with low erosion susceptibility. Therefore, soil conservation measures are important in all soil types to prevent erosion of SOC and maintain soil quality.

Summary: Increased wildfire activity in the western United States has revealed gaps in understanding postfire debris-flow generation. By characterizing flows in an unstudied area, we found that short-duration, high-intensity rainfall is more likely to initiate runoff-generated debris flows compared to total storm rainfall. This finding suggests the need for a focus on localized thunderstorms or bands of intense rainfall during prolonged rainstorms for hazard assessment and warning.

Summary: Frequency analysis of rainfall data is important in hydrological system design and modeling. Advances in weather radar technology allow for higher spatial resolution analysis. Stochastic storm transposition framework shows promise in recreating rainfall statistics from radar data. This study estimates IDF relationships at different scales using a 17-year radar dataset and compares them to rain gauge statistics.

Summary: Different rainfall patterns have varying impacts on soil erosion, with high intensity and low duration rainfall leading to the highest runoff and sediment yield. The study results can contribute to developing new perspectives in designing water erosion experiments with simulated rain, considering the duration, intensity, and their association.

Summary: By analyzing hourly rainfall data in India, we identified six canonical local-scale storm profiles and different characteristics of wet events. We observed an increase in the frequency of convective storm types in recent years, likely due to global warming.

Summary: This paper studies extreme precipitation events in high-altitude cities and proposes an approach to construct IDF curves. By using different parametrization methods and distribution functions, appropriate fitting results are obtained. A spatial interpolation-based analysis is introduced to identify extreme rainfall events based on their duration.

Summary: World extremes in meteorology serve as indicators for climate change and understanding extreme rainstorms is important for assessing climate variability. This article introduces a new dimensionless number, the precipitation intensity duration index (PID), which allows for comparison of rainfall records with different durations. The study shows that the world's greatest rainfall events all have nearly the same PID, and one particular event stands out as the largest point rainfall within documented records.

Summary: In the field of urban hydrology, selecting the appropriate form of the intensity-duration-frequency (IDF) curve is crucial. This study proposes two different formulations of IDF curves, which consider the sub-hourly and super-hourly durations separately. The proposed curves are compared with two well-known IDF formulations that are calibrated using only super-hourly data. The findings suggest that the proposed IDF curves provide the best reliability indicator, considering the different lengths and behavior of sub-hourly and super-hourly data.

Summary: This study develops an environmental contour method to evaluate the impact of rainfall on slope stability and discusses the influence of environmental variables on slope reliability. The method is applied to analyze the reliability of hill slopes in the Peloritani Mountains based on long-term rainfall observations. The findings can be helpful for probabilistic slope stability assessment and design.

Summary: In a warming climate with increased heavy rainfall, the importance of accurate rainfall statistics is growing. This paper proposes a post-processing method to ensure consistency in rainfall data estimates and evaluates it on simulated and actual data, showing consistent and accurate results.
