Snow accumulation refers to the process by which snowfall adds up over time to create layers of snow on the ground. This process is influenced by a variety of factors, such as temperature, precipitation patterns, wind, and topography. Snow accumulation is important for a variety of reasons, including water supply, avalanche forecasting, and winter sports. Researchers in this area study snow accumulation patterns, processes, and impacts in order to better understand and predict how snow cover will change in response to climate change and other environmental factors.
