Summary: This study focused on the effects of climate change on seasonal snow and runoff in the Euphrates River basin, using SWAT model for two headwater basins. Calibration and validation of the model showed good performance with estimated decreases in snow water equivalent and snow-covered days, as well as a slight reduction in runoff volume and an earlier shift in runoff center-time by the end of the century.

Summary: The study in data-scarce snowy areas of Iran found that snow depth and snow cover duration are decreasing trends, mainly influenced by temperature warming. More humid regions experienced more significant reductions in snow depth, while colder regions had smaller decreases in snowy day to wet day.

Summary: In this study, the authors found that using daily precipitation data to drive sediment transport models can lead to significant underestimation of bedload transport capacity. The error introduced can range from 10% to over two orders of magnitude, depending on the location in the channel network. These findings have implications for flood-hazard and aquatic habitat models that rely on coarse-temporal-resolution climate data.

Summary: This study developed an information fusion framework to define the relationship between snow mass and fractional snow cover area, and used machine learning techniques to improve the accuracy and robustness of SDCs in complex mountainous areas. The study area was Northern Xinjiang in Northwest China, and results showed that ML-based SDCs outperformed traditional statistical methods in terms of accuracy.

Summary: The relationship between outgoing longwave radiation (OLR) and surface temperature may not always be linear on seasonal timescales, often taking the form of loops rather than a straight line. In the tropics, OLR loops are mainly caused by seasonal variations in relative humidity out of phase with surface temperature, while in the extratropics, they are mainly due to variations in lapse rates. This suggests that Earth's climate feedback can differ between seasonal and long-term time scales.

Summary: This study investigated the spatiotemporal distribution and correlation of five regulating ecosystem services (RES) in the Qilian Mountains. The results showed that RES were spatially clustered and their distribution was constrained by hydrothermal conditions. The interactions among RES exhibited nonlinear and synergistic relationships, with some conflicts in certain scenarios. Recommendations for land management and biodiversity conservation were provided based on the findings.

Summary: In the mountainous western United States, a warming climate is causing a decrease in the fraction of precipitation falling as snow and a shift in the timing of snowmelt, leading to uncertain impacts on the distribution of water between evapotranspiration and streamflow. By using a Snow Storage Index (SSI) and a Budyko-based framework, this study found that greater snow water storage was associated with greater hydrologic partitioning to streamflow in several mountainous areas. The retention and release of stored snow water during the summer months plays a significant role in water distribution. If SSI decreases with future warming, it will have substantial implications for ecosystems and water supplies in the western U.S.

Summary: This paper aims to explain why high-altitude areas have lower groundwater content by studying factors such as Quaternary deposits and low-flow duration. The results suggest that Quaternary deposits may affect groundwater content, and low-flow duration leads to a lower proportion of groundwater in high-altitude areas. These findings are important for improving theoretical models.

Summary: The article discusses a global seasonal snow classification system that has been revised using new datasets and methods to achieve higher resolution. Researchers utilized global datasets of air temperature, precipitation, and land cover, combined with a micro-meteorological model and European Space Agency data, to create an updated classification. This new high-resolution snow classification dataset is publicly available online and offers improvements and applications at a much higher resolution than previously used.

Summary: The sensitivity of insect populations to environmental conditions can impact their growth, development, and performance. High-elevation and season-limited populations exhibit developmental plasticity, enabling them to advance or prolong development in specific conditions, consistent with field phenology. This plasticity is driven by increased thermal sensitivity of development under short day conditions early in the season.

Summary: This study evaluates snow depth simulations from CMIP6 models in high-latitude regions of the Northern Hemisphere using observational data. The simulated snow depths show low accuracy and a bias towards higher values compared to the observations. While the models indicate an increase in precipitation, the observed snow depth trends during the cold season actually decrease. The findings highlight the need for caution when using and interpreting simulated changes in snow depth.

Summary: Deforestation in tropical mountain regions causes elevation-dependent warming, with the impact varying depending on altitude's role in albedo and evapotranspiration. The warming effect of deforestation decreases with higher elevation, affecting crop yields, land degradation, and nearby ecosystems, suggesting the need for future assessments to incorporate these additional impacts.

Summary: Seasonal snow is crucial in governing the ecology of terrestrial ecosystems, but rising global temperatures are leading to changes in snow conditions. Early snowmelt is associated with advanced spring phenology, while reduced snow depth often leads to increased plant mortality or physical injury. Further research is needed to understand the mechanisms underlying responses to changing snow conditions and their consequences for various ecosystems.

Summary: Accurate prediction of ice crystal number concentration in clouds is crucial for determining radiation budget, cloud lifetime, and precipitation formation. Secondary-ice production is believed to cause observed discrepancies between ice crystal number concentration and ice-nucleating particle concentration. Studies have shown continuous high concentration of secondary ice, likely caused by drizzle drop freezing and recirculation theory introducing melted snowflakes as drizzle drops in clouds. A parametrization of droplet fragmentation at slightly sub-zero temperatures has been introduced, estimating higher splinter production from fragmenting droplets.

Summary: Passive restoration techniques rely on natural plant community succession, but the establishment of native plants in highly degraded soil and competition with invasive species can affect restoration outcomes. Evaluation of three former surface mines showed that native woody plants struggle to establish while invasive species thrive, raising doubts about achieving the desired outcome of a native species forest in significantly degraded habitats through passive management succession.
