Otherwise, snow typically melts seasonally, causing runoff into streams and rivers and recharging groundwater. Major snow-prone areas include the polar regions, the northernmost half of the Northern Hemisphere, and mountainous regions worldwide with sufficient moisture and cold temperatures. Snow, the solid form of water that crystallizes in the atmosphere and, falling to the Earth, covers, permanently or temporarily, about 23 percent of the Earth’s surface.

Understanding the Context

Snow is precipitation that forms when water vapor freezes. Snow falls as ice crystals from clouds when temperatures drop below freezing and there is enough humidity in the air. Snowfall patterns are shifting as the climate warms, with many regions already seeing declines. These shifts impact water supply, ecosystems, winter recreation and hydropower generation.
