Why Does it Snow?
Why does it snow you ask, we will tell.
Why Does it Snow
Primarily, it needs to be cold out for it to snow, lower than 32°F though all the different layers of the atmosphere. As the atmosphere is layered, if they are all not below the freezing point, we could get just plain rain, hail or sleet.
Several Snowflakes patterns
Let’s first start at the beginning with precipitation which can come in several forms. For us to get rain, water vapor in the atmosphere needs what is commonly referred to in the scientific community as a “condensation nucleus”, which can be tiny particles of either dust or pollen which are swept up high into the atmosphere. When the condensing droplets that form the cloud get large and heavy enough to overcome the upward pressure of what is called convection, they start to fall. If the temperature all the way to the ground is above freezing, then we get rain! When ice crystals form high up in the cloud, and it’s below the freezing point of water all the way down, then we will get snow. But when there are alternating layers of air above and below freezing, you get other types of precipitation.
