STUDY OF SNOW DEPTH AND BIOCLIMATIC IMPACT

Abstract: One of the most important climatic elements in a certain area is snow. The amount and depth of snow matter, as they have an impact on the lives of plants and animals, as well as the components of the climate. The scientific techniques used at NOAA provide accuracy and estimates for large climatic zones. The impact of snow depth is related to the water balance, the passage of plant stages, the adaptability of living things, climate change, etc. Climate warming can reduce snowfall and cause earlier spring melts and shorter snow cover seasons. For instance, warmer air in Alaska has caused the snow to melt earlier each spring, lengthening the snow-free summer season. Seasonal snow is an important part of Earth's climate system. Snow cover helps regulate the temperature of the Earth's surface, and once that snow melts, the water helps Fill Rivers and reservoirs in many regions of the world, especially the western United States. In terms of area, snow cover is the largest single component of the cryosphere, covering an average of about 46 million square kilometres (about 17.8 million square miles) of Earth's surface each year. About 98 percent of the Earth's snow cover is located in the Northern Hemisphere. This study was conducted within the project: Evaluation of JPSS satellite and blended snow products, project NOAA, USA;
