Snow occurs when water droplets in clouds freeze, and these droplets then act as a nucleus onto which molecules of water vapor adhere, forming larger ice crystals. Once the growing snowflake is too heavy for the movement of air in the clouds to support, it falls to the ground. Snow can form in any clouds that are below freezing temperature but only does so under the right conditions.Know More
Clouds below freezing temperature do not automatically produce snowflakes. This is because water droplets do not necessarily freeze even at temperatures below zero degrees Fahrenheit. Water droplets in clouds can be supercooled because their molecules must randomly encounter each other in the right way to begin the freezing process. In clouds warmer than minus 31 degrees Fahrenheit, this requires a tiny solid particle to act as a nucleus for crystallization. Particles of clay, dust or biological substances can fill this role, as well as human-introduced nuclei such as silver nitrate or dry ice.
Individual snowflakes vary in shape by the temperature at which they formed. They alternate between flat, plate-like shapes and longer, thin shapes as temperature decreases. The nuclei on which the snowflakes formed also influences their final shape. Most snowflakes are visibly irregular.Learn more in Snow
Snow is made out of tiny ice crystals that stick together. The tiny ice crystals form when the temperatures are low and there is moisture in the atmosphere.Full Answer >
Snow forms in the atmosphere when the proper temperature and moisture conditions are met. For snow to materialize, temperatures must be below freezing, or around 32 degrees Fahrenheit, and there must be a slight amount of moisture present in the air. In order for snow to have the best chance of reaching the ground, temperatures must be at or below freezing.Full Answer >
Snowstorms are storms characterized by a significant volume of snow with accompanying high wind. A massive snowstorm with intense snowfall and strong winds that lasts for a long period of time is called a blizzard.Full Answer >
A snow squall is defined as an intense, heavy snowfall with strong winds and a possibility of lightning. The amount of snowfall is significant. Another term used to describe a snow squall is a whiteout.Full Answer >
