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
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 >
Snow forms when atmospheric water vapor freezes onto a pollen or dust particle, which creates an ice crystal. As it falls, more water vapor freezes onto the ice crystal to create snowflakes.Full Answer >
On average, snow weighs between 7 pounds per cubic foot and 20 pounds per cubic foot, according to North Dakota State University. The discrepancies can be attributed to the physical state of the ice, its depth and the atmospheric temperature; fluffy snow is light, while compacted snow is heavier.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 >
