Summary: This study investigates the intraseasonal variability of cloud vertical structure (VSC) during the Indian summer monsoon (ISM) using data from CloudSat. The study finds significant differences in VSC over different regions of India, with contrasting patterns during active and break spells of the ISM. The research contributes to a better understanding of cloud-related processes and improves the predictive capabilities of large-scale models.

Summary: This study investigated spatial and seasonal patterns of precipitation in Louisiana to elucidate crop exposure to water deficits at a regional scale. Through the use of regionalization techniques and kernel density estimators, two distinct precipitation regions were identified, and the probability distribution of seasonal precipitation was assessed. Crop water requirements for various crops under different planting scenarios were then used to evaluate the probabilities of crop exposure to water deficits during the growing seasons. The outcomes aim to provide irrigation management recommendations for farmers in Louisiana.

Summary: This study analyzes the sub-seasonal clustering of precipitation extremes in Switzerland and its link to extreme river discharge. The temporal clustering of precipitation extremes exhibits a distinct spatiotemporal pattern, occurring primarily on different sides of the Alps during different seasons. The occurrence of a cluster of precipitation extremes generally increases the likelihood and duration of high-discharge events, particularly at low elevations.

Summary: This study investigates the disparity in precipitation trends among global climate models in predicting the future precipitation trends in the southwestern United States. The results show that future precipitation trends are linked to the present-day atmospheric circulation and the models' representation of climatological features.

Summary: The study in western central Morocco identified three homogeneous rainfall regimes, with the coastal area receiving heavy rainfall in autumn and winter, and the mid-mountain area experiencing the highest precipitation, especially in summer. The analysis of daily rainfall extremes revealed high precipitation amounts in the coastal region and exceptional daily precipitation for longer return periods. The spatial distribution of extreme precipitation events showed an increase towards the Atlas mountains and the Atlantic Ocean, highlighting areas where stormwater management needs improvement and where floods are more likely to occur in the future.

Summary: This study analyzed spatio-temporal fluctuations in rainfall in Khyber Pakhtunkhwa, Pakistan to evaluate drought and wet spell patterns, identifying a decreasing trend in rainfall in some areas, while others experienced an increasing trend. The study used the SPEI and SR tests to assess drought and wet spells, providing valuable insight for water resource planning and management.

Summary: Rainfall characteristics in monsoon regions, such as the frequency and intensity of rainfall events, show significant decadal variability. This study reveals that the modulation of rainfall characteristics in Senegal is strongly linked to both the Atlantic multidecadal variability and the interdecadal Pacific oscillation. Understanding these variations is crucial for understanding rainfall patterns in monsoon regions.

Summary: The study analyzed the temporal and spatial variations of precipitation variability on the Qinghai-Tibet Plateau using the standardized variability index (SVI) based on entropy. It found that precipitation has become more uniform in the southwest foot of the Himalayas and the border zone between barren and grassland areas. However, this trend is expected to reverse in the future, potentially leading to natural disasters. The study also identified the influences of factors such as the Asian monsoon, westerly jets, sea-land thermal difference, and Sea Surface Temperature (SST) on precipitation variability.

Summary: This study analyzed the phytoplankton communities in the upper 100 m of the Gulf of Cadiz and the Alboran Sea using time series data. The results show that these two regions can be considered as two differentiated bioregions, with the latter having higher productivity.

Summary: This study examines the relationship between low decadal mean precipitation and monthly-scale wet and dry extremes over the global land area. The research found that changes in wet extremes are most significantly associated with low decadal mean precipitation, while shifts in the mean of precipitation distributions play an important, but typically secondary, role in dry decades. There is a negligible role for changes in variance, and a decadal-scale decline in mean precipitation does not necessarily lead to an increase in the severity of seasonal-scale drought.

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: Accessibility and variability of water resources have significant impacts on social, political, and economic security. This study investigates the integration of a locally-tailored seasonal precipitation forecast into agricultural decision-making and finds that the forecast can improve farmer agents' benefit. The sequence of precipitation conditions, risk preference, and community-level social dynamics also play important roles in forecast adoption.

Summary: This qualitative study analyzes the experiences of those living in flood-prone economically constrained communities, focusing on relocation, risk perceptions, and communication. The findings suggest that communication plans for flood-prone communities should emphasize economic opportunities instead of flood risks, while communication in relocated communities should prioritize safety and overall quality of life, considering the economic stresses people face.

Summary: In this study, a statistical model was developed to predict cyanobacteria biomass and associated beach closures in a eutrophic lake in Wisconsin using local and global scale hydroclimatic predictors. The model showed significant skill in comparison to cyanobacteria observations from June to August, offering the possibility of advance warnings and improved beach management.

Summary: The direct cost of natural disasters globally reaches hundreds of billions of USD per year, while water resources face increasing stress and variability. Low- and middle-income countries bear much of the burden, despite their relative lack of wealth, and suffer measurable GDP impact. Vulnerability to extreme events is heterogeneous globally and at the subnational level. Disaster managers and relief organizations are increasingly using climate information services to mitigate risks, but targeting vulnerable communities remains challenging. Forecast-based anticipatory action programs offer opportunities for pre-disaster preparedness, but their effectiveness varies depending on forecast skill, disaster type, lead time, and location. By considering vulnerability and forecast skill at multiple scales, this analysis identifies promising locations for anticipatory action protocol development.
