Summary: This study quantified the range of sub-daily extreme precipitation due to internal variability using the Canadian regional climate model. Results show an increasing trend of extreme precipitation over time, with short-duration rainfall intensities increasing more than longer-duration rainfall. Variations in the scaling of precipitation increase with temperature were significant among the 50 model members.

Summary: A novel hierarchical Bayesian quantile regression model is proposed to estimate the relationship between precipitation and temperature in different seasons, weather regimes, and precipitation percentiles. The study finds that the scaling rates of regional precipitation vary depending on the season and percentile, while the variations across different weather regimes are modest.

Summary: This study examines the spatial distribution of scaling relationships between extreme precipitation and temperature in South Korea, considering different scales and seasons. The results show significant variations in scaling patterns across regions and temperature variables, with a peak-like structure observed in most cases. There is also a notable increase in extreme precipitation at high quantiles in the southern area of South Korea. These findings highlight the importance of interpreting precipitation scaling within specific spatiotemporal contexts for understanding future extreme precipitation events.

Summary: This study investigates the relationship between atmospheric variables and properties of convective rain cells, and finds that convective precipitation exceeds the Clausius-Clapeyron rate under current climate conditions. The study also reveals that different cell properties scale with dew point temperature at varying rates, and that wind shear increases precipitation by increasing the spatial cell extent.

Summary: Global warming has significantly impacted precipitation extremes by altering the energy budget and water cycle of the land-atmosphere system. This study quantifies the global-scale responses of precipitation extremes to near-surface air temperature and dew point temperature using the ERA5 reanalysis dataset. The results reveal a "hook" structure between precipitation extremes and temperature, with various factors influencing this relationship.

Summary: This study investigates the association between daily precipitation extremes (PEX) and maximum daily temperature (T), dew point temperature (DPT), and precipitable water (PW) in India from 1979 to 2016. The relationship between PEX and physical covariates is modeled using copula for selected cities with different climates. The largest scaling coefficients are observed in Mumbai, with negative scaling with T and positive scaling with DPT. The median value of rainfall extremes increases with decreased T and DPT, but increases with increased PW for all cities. Future scaling analyses using ensemble mean of 13 General Circulation Models (GCMs) show negative to slight positive scaling with T across India.

Summary: Based on long-term observations, a peak structure exists in the relationship between precipitation and temperature in most regions of China. The scaling rate decreases spatially from southeast to northwest in the wet season, while sub-C-C scaling dominates most regions in the dry season. Mixing precipitation events from different seasons could result in miscalculations of the precipitation-temperature scaling rate. The significant increases in high percentiles of precipitation in southern regions of China during the historical period indicate that the peak structure does not imply an upper limit for precipitation extremes. Our results highlight the importance of considering seasonal characteristics when analyzing the extreme precipitation-temperature relationship in a changing climate.

Summary: The convection-permitting climate model, WRF-ARW, is able to capture the relationships between precipitation extremes and temperature in western Canada. This is due to the stable annual cycle of the regional climate, which governs the PT scaling pattern. The intensification of precipitation extremes in a warmer climate is projected to be particularly pronounced in the coast of western Canada.

Summary: This study analyzed the scaling relationship between extreme hourly precipitation and temperature in 14 urban locations in India. The findings show a negative scaling relationship during the monsoon season, which decreased after the global climate shift of 1975 in most locations. However, during the non-monsoon season, the scaling coefficient was slightly positive and consistent with the Clausius-Clapeyron scaling rate. The study also examined the scaling relationship using dew point temperature (DPT) as a variable, and found positive scaling in several cities in both seasons. Super-CC scaling was observed with DPT in some cities during the monsoon and non-monsoon seasons. This analysis provides insights into the regional and seasonal distribution of hydrological extremes and their impacts on urban infrastructure design.

Summary: The sensitivity of AR-induced precipitation to climate change is primarily driven by increases in atmospheric water vapor with warming. This study examines the scaling rates of extreme precipitation with temperature for AR and non-AR events in California using multiple statistical models. The results show that the regional scaling rates for ARs are consistently larger than non-ARs, especially for hourly event maxima. This difference in scaling rates can be explained by the fact that ARs remain near saturated and exhibit more lift and a stronger increase in specific humidity aloft with warming compared to non-ARs.

Summary: Extreme precipitation poses a major challenge for local governments, and reliable future precipitation projections are needed. This study found that changes in storm-total precipitation depend strongly on storm type, and the most common type of storm event could lead to a 26-37% increase in storm-total precipitation in the future.

Summary: Recent studies have focused on understanding short-duration rainfall extremes and their impacts on flash floods, landslides, and debris flows. With global warming, the intensity of long-duration heavy precipitation increases, with rare events and localized short-duration intensities potentially scaling at higher rates. Further research and international coordination are needed to better detect and understand changes in intense short-duration rainfall.

The results reveal that the quantile regression approach shows more regularity and promising potential in predicting extreme precipitation in these areas.

Summary: The Weather Research and Forecasting (WRF) model was used to simulate current and future climates in eastern China. Historical climate was modeled for a continuous 10-year period, and three pseudo-global warming experiments were conducted for the year 2070-2099 under different scenarios. The simulations showed an increase in precipitation intensity in most regions, especially in North China under the RCP8.5 scenario. However, the frequency of precipitation was projected to decrease, particularly in the Yangtze River Basin during summer. Extreme events were projected to increase in intensity and frequency, with the greatest increase under the RCP8.5 scenario.
