When the weather begins to get warm after it has snowed and the snow begins to melt, there are actually a number of complex and important physical processes taking place. Heat is absorbed and converts the snow particles into water, which then makes its way to the ground. A number of different important factors can determine the rate at which this snow melting process takes place.Know More
Snow melting relies heavily on air temperature and the intensity of the sun. Other factors are also important to a lesser extent, like the speed and temperature of the wind and whether it is raining. The terrain on which the snow has fallen and its angle to the sun is also fundamental.
When the temperature begins to rise and the heat from the sun reaches the snow, the melting process begins. Because the top layer of snow is the first to receive this energy from the sun, snow melts from top to bottom. The energy in the heat turns the snow into water by breaking down the snow crystals. When the bonds holding these crystals together get too weak, they cannot overcome the forces of gravity, and drops begin to trickle to the ground. These first warm water drops also contribute to raising the temperature of the snow and speeding up the melting process.Learn more about Snow
Snow is made up of small ice crystals and is perfectly edible most of the time. The only time it is potentially dangerous to eat snow is when it is contaminated.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 >
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.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 >
