JOURNAL FREE ACCESSIn order to predict the energy exchanges in a blowing snow layer, a simple vertical multilayer energy exchange model for blowing snow has been developed. Using this model, the fundamental elements characterizing the energy exchanges in a blowing snow layer have been analyzed at intervals of 0.01m between heights of 10 m and 0.1m from the snow surface at friction velocities of 0.5m/s and 0.75 m/s. The results of this analysis are as follows: 1) The effects of blowing snow on downward shortwave radiation are not as significant as those on downward longwave radiation; downward shortwave radiation decreases while upward shortwave radiation increases with a decrease in the height from the snow surface. Both these shortwave radiations change significantly near the snow surface. 2) Since blowing snow particles increase the emissivity of a blowing snow layer, downward longwave radiation increases with a decrease in the height from the snow surface; a change in upward longwave radiation, however, is small due to the high emissivity of the snow surface. 3) Blowing snow causes wind to become weak. 4) Air temperature and specific humidity change significantly near the lower layer with an increase in the number of particles. These results for the fundamental elements characterizing the energy exchanges in a blowing snow layer are consistent with those obtained by field observations and wind tunnel experiments.View full abstractDownload PDF (5678K) -

JOURNAL FREE ACCESSThe large-scale distribution of snow cover in the Northern Hemisphere, derived for the last three decades from satellite imagery, was described along with its seasonal variations and long-term trend. Further, recent developments in research on the interactions between snow and atmosphere were reviewed. The phenomena considered were of sub-continental to hemispheric scales in space, and synoptic to sub-decadal scales in time. Specifically, the inverse relationship between Eurasian snow and the Indian monsoon, and the interactions between continental snow cover and the dominant modes of circulation variability were studied.View full abstractDownload PDF (4954K) -

JOURNAL FREE ACCESSThe largest cryospheric components on Earth are the frozen grounds that occupy approximately 60% of the northern hemispheric land areas; these regions influence climates and water cycles on various spatio-temporal scales. Nevertheless, many hydro-meteorological studies on cold regions have only implicitly considered frozen ground processes. This situation requires a thorough change in the light of recent global warming issues; future studies should focus on more explicit representations of frozen grounds and their interrelation to the climate, meteorology, and hydrology. This study includes the different aspects of frozen grounds that are essential for a basic understanding of interdisciplinary perspectives such as frozen ground definition and geometry, active layer dynamics, hydro-thermal regimes of active layers, water and energy interaction between the active layer and atmosphere, and hydrological distribution modeling from drainage to global scales. It is crucial to have a greater correlation between observation and modeling by considering observational enhancements to include wider areas for model verification and more accurate representations of the hydrothermal processes within the soil derived from observations.View full abstractDownload PDF (10052K)
