Summary: At a continental scale, changes in snow ablation events inform regional hydroclimate, affecting streamflow, soil moisture, and groundwater supplies. The study shows a significant decrease in snow ablation frequency over time, with some regions experiencing up to a 75% decline in events, mainly due to reductions in snow cover.

Summary: The study aimed to improve understanding of spatial and temporal variability of refreezing in the Himalaya. Results showed significant spatial variability of refreezing amounting to 122 mm w.e. annually, with a seasonal altitudinal variability related to air temperature and snow depth. Daily refreezing simulations decreased by 84% compared to hourly simulations, emphasizing the importance of using sub-daily time steps to capture melt-refreeze cycles.

Summary: This study addresses the impact of climate change on winter temperatures and snowmelt hydrology across most of the eastern US from 1960 to 2019. It finds that warmer winters have become more frequent in recent decades, leading to significant changes in snowpack, snow duration, and streamflows.

Summary: The Atwater Study Plot (ASP) is one of the oldest snow observation sites in the Western United States, located in Alta, UT. It has been primarily focused on snow safety and avalanche forecasting, but since 2017, the Snow HydRO Lab at the University of Utah has been conducting hydrology-focused snow pit observations within the study plot. In 2019, additional instruments were installed to observe continuous snow energy and mass balance, making ASP the first snow energy balance study plot in the Wasatch Mountains.

Summary: This study compares the climate sensitivity of hydrology in two basins in eastern Canada, and finds that both basin landscape and regional climate influence the hydrological response to climate change. The study also reveals that projected peak snow water equivalent (SWE) is highly sensitive to warming, with landscape conditions playing a moderate role. The results show that landscape conditions mediate various hydrological processes and streamflow responses to climate change.

Summary: The timing of snowmelt runoff is important for water resource applications and is affected by regional climate change. However, detailed measurements of snowmelt timing in mountainous regions are challenging. In this study, we developed a method to map snowmelt using satellite radar data and investigated the relationship between elevation and snowmelt onset over the past 8 years. We found that snowmelt onset is strongly dependent on elevation and observed variations in snowmelt timing during the 2015 snow drought and between 2016 and 2022. Our work provides valuable insights for understanding regional climate change and managing water resources.

Summary: Rain-on-snow events have a significant impact on the hydrological regime of rivers in regions with seasonal snow cover. Analysis shows that only a small percentage of ROS events result in high runoff, while most events do not cause a significant increase in runoff. High volumes of rain and low snow cover are identified as important factors in generating high runoffs.

Summary: This paper simulates the ground snow loads in six regions of China over nearly 60 years using a multi-layer snowmelt model and calculates the ground snow loads for a 50-year recurrence interval using various probabilistic models. The results show that the snowmelt model accurately reproduces the process of ground snow events and can obtain extreme samples.

Summary: Snow plays a crucial role in the hydrological cycle of the Western Himalaya, with snowmelt providing water for downstream regions. This study investigated the future evolution of snow cover and snowmelt in the Panjshir catchment of Afghanistan, using global climate models to simulate and predict changes. The results suggest a projected decrease in snow cover area, with implications for water resources and water-dependent sectors in the region.

Summary: In this study, a continuum model is proposed to investigate the transport of meltwater through porous snow. The model considers the nonlinear coupling between preferential melt flow and nonequilibrium thermodynamics at the Darcy scale. The model is validated against field data and laboratory experiments, showing good agreement. The simulations reveal that preferential infiltration can deliver melt faster to deeper depths, leading to changes in porosity and temperature. The formation of vertical low porosity annulus, known as ice pipes, is also captured by the model. The results highlight the importance of considering melt refreezing and unstable infiltration in understanding the porosity structure and transport processes in snow.

Summary: Spatial and temporal dynamics of rainfall and snowmelt control the availability of water resources in the rain-snow transition zone of the western United States. The sensitivity of spatiotemporal surface water inputs (SWI) across different water years is poorly understood. A study conducted in a headwater catchment in Idaho modeled rainfall and snowpack dynamics for two hydrologically distinct years. The results showed that SWI is influenced by total precipitation, snow drifts, elevation, and slope aspect. The distribution of SWI is expected to change with declining snowfall and redistribution as the climate warms.

Summary: Historical patterns of snow cover and snowmelt are shifting due to climate warming and perhaps some human activities. In this study, the long-term impact of climate warming on snowmelt rates in China's three main stable snow cover regions was evaluated using passive microwave remotely sensed data. The results showed a decline in annual maximum snow water equivalent (SWE) and a decrease in moderate and high rates of snowmelt. Vegetation improvement was also found to be closely related to the slower snowmelt rate in these regions.

Summary: This study compares the performance differences of various hydrological models in simulating snow ablation, finding that net radiation has a stronger correlation with melt rates during the ablation period. Differences between models and observations in the last snowfall date and responses to vegetation cover changes were also identified.

Summary: This study indicates that the Assiniboine-Red River basin will experience seasonal warming and changes in precipitation distribution in response to global mean temperature changes, leading to wetter winters and springs and drier summers and autumns. Additionally, the snow water equivalent responses are mainly temperature-controlled rather than precipitation-driven.

Summary: This study assesses the impact of large-scale atmospheric and surface climatic conditions on spring freshets in major Arctic-draining rivers by analyzing historic daily discharges. Results show that climatic variations closely match the observed trends of increasing cold-season flows and earlier freshets. The study also finds that regulation may suppress the effects of climatic drivers on freshet volume but has no significant impact on peak freshet magnitude or timing measures.

Summary: The study found that snow water equivalent, April 1st snow water equivalent, and spring precipitation are the most important predictors of annual maximum flows and mean spring flows in western Canadian river basins. The MLR framework is useful for assessing the spatial variation in hydroclimatic controls. Future projections show significant spatial variations in annual maximum and mean spring flows.
