Summary: Ground surface temperature (Ts) was manually measured in the past, but inconsistency was found when compared to more recent automatic measurements. In this study, observations from northeastern China were used to explore and correct this inconsistency. The results showed that the inconsistency varied depending on snow conditions and time periods considered. Removing this inconsistency is critical for soil and climate investigations.

Summary: In 2019, the town of Pernik in Bulgaria faced a severe water supply crisis due to the insufficient inflow to the Studena reservoir. The study conducted on the watershed and reservoir inflows confirmed that the main reason for the low inflow was the decrease in precipitation, especially snowfall, which was influenced by the increase in average air temperature.

Summary: Soil thermal conductivity (STC) is an important parameter for understanding thermal changes in soil, especially in permafrost regions. Different STC schemes incorporated into land surface process models (LSMs) can lead to large errors. This study evaluated nine normalized STC schemes in simulating soil thermal regimes on the Tibetan Plateau and found that the scheme including minerals, soil organic matter, and gravel soil performed the best. The BA2005 scheme showed the best performance among the selected schemes.

Summary: As the Arctic continues to warm at a faster rate compared to the rest of the planet, the hydrological cycle intensifies with increased precipitation and evaporation, leading to a projected earlier transition from a snow- to rain-dominated Arctic in the summer and autumn at potentially lower levels of global warming. The latest CMIP6 models show a faster Arctic warming and sea-ice loss, highlighting the need for increased attention to the environmental changes happening in the region.

Summary: Soil temperature plays a crucial role in climatology, hydrological modeling, and environmental simulations. The study demonstrates that the modified DNDC model performs better in simulating soil temperature under specific conditions in arid and semi-arid regions. It shows good applicability and expandability, making it an effective tool for predicting soil temperature and informing agricultural strategies.

Summary: Economic losses from snow-related disasters in China's pastoral areas have worsened in recent decades. Predicting snow distribution and depth is challenging due to complex terrain and wind conditions. To address this, a comprehensive simulation method is proposed that combines computational fluid dynamics prediction, snowdrift simulation, and snowmelt simulation. The approach was validated using a historical snow event in Tacheng City, China, and it can aid the government and the public in mitigating snow risks through policy and technique considerations.

Summary: This study investigates the temporal and spatial variations in soil moisture and temperature due to snow and its melt in different elevation regions. The results show that high elevation sites have longer snow cover compared to low elevation sites. The study suggests that artificial snow may potentially influence groundwater quality.

Summary: This paper presents an automatic snow-melting membrane roof based on an electrical-thermal system (ASMR-ETS), which can be used to clear snow on membrane roofs. Through thermal simulation and experiments, the feasibility of the system is verified, and the snow-melting performance under different parameters and climatic conditions is analyzed.

Summary: This study analyzes the snow dynamics in an Arctic ecosystem manipulation experiment on Disko Island, West Greenland, over 8 years. The results show that snow depth is the decisive factor affecting the difference between soil and air temperature, and there is a lagged effect of snow on soil temperature.

Summary: This study aims to evaluate the effects of temperature and relative humidity on COVID-19 transmission and provide recommendations for indoor HVAC design and policy development. A cumulative lag model was proposed to assess the impact of temperature and relative humidity on transmission. Results showed a lagged effect with the peak relative risk occurring at a lag of 3-7 days in most regions. The study provides targeted strategies for outbreak prevention and controlling transmission.

Summary: Temperature lapse rate (TLR) plays a crucial role in the simulation of snow/glacier melts in alpine watersheds. However, the traditional method of estimating TLR based on a limited number of weather stations may not be suitable for alpine watersheds with sparse observations. To address this issue, this study developed a new basin-oriented TLR scheme based on MODIS land surface temperature data and applied it to a glacierized watershed in the Himalayas. The results showed that the new TLR scheme provided more reasonable estimations of TLR and performed better in simulation of snow cover area and runoff compared to the traditional scheme. This study offers an efficient framework for estimating TLR in alpine watersheds with limited observations using remote sensing.

Summary: The study found a positive correlation between traffic volumes and building wall temperature (BWT) and road surface temperature (RST) in Jorhat municipal area, with the correlation being stronger with RST, especially in shadowed areas. The relationship between traffic volume and RST and BWT is significantly stronger during midday and afternoon periods. Urban areas with high traffic congestion are identified as having higher BWT and RST.

Summary: This study investigates the snowmelt situation in the Umbria-Marche Apennines in central Italy, showing non-significant decreases in snow cover height and duration, contrary to the significant increasing trend of mean temperature. A mathematical model is developed to predict snowmelt on the ground.
