Summary: Research indicates that interannual variations in total precipitation in California are primarily influenced by precipitation frequency, which is related to the position of the North Pacific jet stream. This suggests that California's precipitation frequency is primarily controlled by the positioning of the jet stream guiding precipitate weather systems.

Summary: This study conducted regional frequency analysis of annual maximum daily rainfall in Skane County, Sweden, indicating it is a homogeneous region. The support vector machine model was found to be appropriate for finding index rainfall at ungauged sites. Site characteristics, elevation, and latitude were identified as key variables for explaining the variation in mean annual maximum daily rainfall.

Summary: This study proposes a methodology for assessing mean annual maximum rainfall at sub-hourly scale by combining historical and newer time series data. A linear correlation is found between rainfall maxima with different durations, enabling the use of mechanical station data for sub-hourly assessments.

Summary: The study evaluates the accuracy of Integrated Multi-satellite Retrievals for GPM (IMERG) V06 satellite precipitation products at high latitudes in Finland. Results show IMERG SPPs are reliable in Southern, Eastern, and Western Finland but caution is needed in the historical province of Oulu and not recommended for Lapland. IMERG-Final SPP performed best, recommended for use to supplement or substitute ground precipitation measurements in ungauged regions in Southern Finland.

Summary: This study investigated the synchronous responses of vegetation to extreme temperatures and precipitation in middle-to-high latitudes in Asia. The results revealed that areas with maximum or minimum leaf area index (LAI) expanded or contracted with global warming. Both GIMMS and GLASS LAI peaked in spring and autumn, while reaching their respective minimums in different seasons. The datasets were consistent in showing how vegetation responds to extreme climate conditions, particularly in tree-covered areas.

Summary: As the climate warms, precipitation becomes more intense, especially in the autumn. The increase in convective precipitation frequency and intensity dominates the climate change signal, but there are deviations in the precipitation response in autumn and spring.

Summary: This study analyzes the spatial variability of rainfall time structure in high precipitation events in Czechia using weather radar data and rain gauge measurements. The results indicate that topography significantly affects the rainfall time structure, with the impact amplifying with the increasing return period of precipitation totals. Additionally, mountainous areas exhibit distinct rainfall characteristics compared to lowlands.

Summary: This study investigates the influence of low-frequency oscillation on persistent abnormal precipitation in Southwest China and reveals the configuration relationship of low-frequency systems in three-dimensional space. The results provide a theoretical basis for forecasting the extended period of persistent heavy rain in this region.

Summary: This study establishes the relationship between annual bifacial photovoltaic module energy gain and latitude, and validates it by comparing theoretical and experimental values. It also discusses the impact of diffuse irradiance and latitude on annual energy gain, and creates an annual energy gain model for modules located at low latitudes.

Summary: This study evaluates twelve probability distributions to identify the best model for extreme rainfall estimates in Egypt. The top three distributions for frequency analysis of daily annual extreme rainfalls in Egypt are Log-Normal, Log-Pearson Type III, and Exponential. The performance of both L-moments and maximum likelihood methods is better than the method of moments for rainfall frequency analysis.

Summary: Estimating precipitation in Alaska using weather radars is challenging. The study uses NWS precipitation products and radar data to evaluate the accuracy of precipitation estimates, with a focus on the difficulties in estimating precipitation in cold temperatures. The NWS Precipitation Processing Subsystem shows better performance in the mixed precipitation phase, indicating adaptation to the climatology of precipitation in Alaska.

Summary: Current water demands in the UAE are being met, but climate change and increasing water demand pose challenges for water resource management. The study shows an overall increasing trend in precipitation, with significantly lower levels in the early 21st century compared to the late 20th century. The eastern part of the UAE exhibits more pronounced variations in precipitation trends.

Summary: This study applies new satellite datasets and methodologies to explore the physical relationship between lightning and precipitation in mid-/high latitudes. The study finds that convective precipitation features (cPFs) with lightning in mid-/high latitudes have unique characteristics, such as lower temperatures and smaller range of microwave brightness temperatures. Additionally, cPFs with low flash density are more sensitive to environmental factors.

Summary: Ice roads and bridges are commonly used transportation routes in the circumpolar north during winter. Monitoring ice conditions throughout the season is important for ensuring safety. This study tested the accuracy of ground penetrating radar (GPR) in measuring floating ice thickness under different conditions and found that environmental factors such as snow cover and overflow can affect the validity of an average velocity model for ice thickness identification using GPR, while frazil ice accumulation does not have a detectable effect on radar reflection.
