Snowfall occurs when temperatures in the atmosphere are low enough for water vapor to freeze and form ice crystals, which cluster together to create snowflakes. These snowflakes fall to the ground when the air near the surface is cold enough to prevent melting. Snowfall can range from light flurries to heavy snowstorms, and it is more common in regions with colder climates, such as the Arctic or mountainous areas. Snow is important for replenishing freshwater resources and can also create scenic winter landscapes, though it can cause disruptions such as travel delays and power outages.
