About this Research Topic
The cryosphere is a key component of the Earth system. The distribution of regional snow/ice cover is affected mainly by factors such as wind, topography, snowfall, and temperature. As global warming continues, extreme weather and climate events frequently occur, including snow/ice disasters. There are several types of snow/ice disasters on different spatial scales, such as snow and ice avalanche, drifting and blowing snow, snowstorm, flood, building collapse, traffic hazards, snow and ice accretion, etc., which cause great damages to human lives and the social economy. Thus, studies on the physical processes and formation mechanism of snow/ice disasters, prediction and early warning systems, as well as control engineering are of great significance to preventing snow/ice disasters from damaging the society.
This research topic focuses on 1) blowing/snowing processes influenced by the coupling effect of multiple factors, such as topography, turbulence, solar radiation, temperature, humidity and precipitation. These processes involve gas-solid two-phase flow, particle-bed interaction, physical phase change, etc., and are typically complex, nonlinear and multiscale. The understanding of the mechanisms governing such processes and development of numerical models have both scientific importance and practical applications; 2) Evolution of snow/ice distribution at different scales, from microscale physical mechanism of snow cover variation to feedbacks between snow/ice distribution and climate change on global scale, a topic coupling mechanics, atmospheric sciences, earth sciences, and other disciplines; 3) Topics in areas of snow/ice disaster formation mechanism and control engineering, which provide the foundation and references for future scientific research in prediction and prevention of snow/ice disasters.
