Abstract
Abnormally heavy snowfall occurred over central and northern Japan during the winter of 2024/2025, when sea surface temperature (SST) over the Sea of Japan was anomalously high in December to mid-January. We investigated how the SST influenced precipitation, snowfall, and snowpack characteristics during this period. Two numerical experiments using the Weather Research and Forecasting model were conducted: realistic and sensitivity experiments in which SST anomalies over the Sea of Japan were removed. We determined that high SST over the Sea of Japan in this winter enhanced precipitation and snowfall along the western coastal regions of Japan, although the response exhibited regional differences. Precipitation and snowfall increased more in northern Japan than in central Japan. Furthermore, snow density increased in northern Japan. These findings highlight that anomalously warm SST over the Sea of Japan can influence not only snowfall amount, but also snowpack characteristics, with spatial heterogeneity.
In heavy-snowfall mountain basins, seasonal snowpack acts as an important reservoir for winter precipitation, yet applications of SWAT+ to such basins on the Sea of Japan side remain limited. We developed a SWAT+ model for the Tedori River Basin (691 km2) in Ishikawa Prefecture, Japan, and evaluated how the precipitati...

The study analyzes the spatiotemporal characteristics of snow cover across the territory of Kazakhstan during the winter season of 2024...2025, and also evaluates long-term trends in the main snow cover characteristics (number of days with snow cover, maximum snow depth, and snow water equivalent) for the period 1970.....

During wintertime cold-air outbreaks (CAOs) from Siberia, wind-parallel sea-effect cloud bands over the northeastern part of the Sea of Japan (NE-SOJ) often exhibit oscillations with a prominent semidiurnal cycle, causing periodic snowfall where they make landfall on the western coast of Hokkaido Island, Japan. To el...

In the Republic of Kazakhstan, runoff in lowland rivers is 90% determined by snowmelt. Therefore, assessing snow reserves in a changing climate is of great scientific and applied importance. This work aims to assess how global climate change affects snow cover characteristics in Western Kazakhstan in the Caspian Sea ba...

In two consecutive papers, we tried to fill a knowledge gap in the snow research in the Bulgarian mountains and to estimate the current snow conditions in these regions. In the previous study, we encountered a significant increase in mean winter air temperatures at all elevations, weaker changes in winter precipitation...
