What are the 5 categories of snow?

This article is about different snow types and how they are formed. There are two variables that determine snow type, temperature and air moisture. Snow comes in five general types: graupel, plates, needles, columns, and dendrites. Each snow type forms in different temperatures and moisture levels.

What is the classification of snow?

In the US, the intensity of snowfall is characterized by visibility through the falling precipitation, as follows: Light snow: visibility of 1 kilometre (1,100 yd) or greater. Moderate snow: visibility between 1 kilometre (1,100 yd) and 0.5 kilometres (550 yd) Heavy snow: visibility of less than 0.5 kilometres (550 yd)

A snow squall is a brief, but intense snowfall that greatly reduces visibility and which is often accompanied by strong winds.

What is chalk snow?

What is sugar snow?

A sugar snow is a heavy, spring snow that insulates the bases of the sugar maple trees from the deep freeze of winter while simultaneously keeping the forest cool enough to prevent early leafing. You see, a heavy snow helps to keep the ground from freezing hard too deep down into the soil.

Can you eat snow?

Scientists have found that new snow can contain weird stuff including pesticides, soot and even nasties such as mercury and formaldehyde. All of these things are found at extremely low levels — which means it's technically safe to eat.

What is rain and snow mix called?

What are big snowflakes called?

(See Snowflake Watching for more about observing snowflakes.) Sometimes the branches of stellar crystals have so many sidebranches they look a bit like ferns, so we call them fernlike stellar dendrites. These are the largest snow crystals, often falling to earth with diameters of 5 mm or more.

What is hoar ice?

Table of Contents. hoarfrost, deposit of ice crystals on objects exposed to the free air, such as grass blades, tree branches, or leaves. It is formed by direct condensation of water vapour to ice at temperatures below freezing and occurs when air is brought to its frost point by cooling.

Is hail snow?

So what's the difference? "Snow is made up of one or more tiny ice crystals that come together to form the intricate and unique shapes of a snowflake," says ABC weather specialist and presenter Graham Creed, "Whereas, hail is a frozen raindrop and is generally a lot bigger than a pure crystal of ice."
