What is snow?
Snow is defined as 'solid precipitation which occurs in a variety of minute ice crystals at temperatures well below 0 °C but as larger snowflakes at temperatures near 0 °C.' It is one of the UK's most striking weather phenomena causing a transformation of the world around us, but it can also lead to the potential for disruption.
How does snow form?
Snow forms when tiny ice crystals in clouds stick together to become snowflakes.
If enough crystals stick together, they'll become heavy enough to fall to the ground.
Snowflakes that descend through moist air that is slightly warmer than 0 °C will melt around the edges and stick together to produce big flakes.
Snowflakes that fall through cold, dry air produce powdery snow that does not stick together.
Snow is formed when temperatures are low and there is moisture in the atmosphere in the form of tiny ice crystals.
How cold does it have to be to snow?
Precipitation falls as snow when the air temperature is below 2 °C.
It is a myth that it needs to be below zero to snow
