The snow ratio is important to understand

 On new years eve 2021, the exact phrase "The snow ratio is important" does not appear in a Google search.

Nor does it show up on Bing or duckduckgo 

The snow ratio is important to understand why there is more, or less snow, from the same amount of precipitation.

You may have heard that you can melt 10 inches of snow to an inch of water. But is that really true?

While this rule of thumb is valid at times, there are factors in the atmosphere which can result in higher or lower snow amounts from that same inch of water. Meteorologists call this the snow ratio, and it plays an important role in snow forecasts for a given storm, in addition to determining a weather system's future path.

In general, lower snow ratios result in wet, heavy snow accumulations commonly found in early and late-season storms. That type of snow is difficult to shovel, and sometimes can down trees and power lines. Conversely, higher snow ratios lead to light and fluffy accumulations, often prone to blowing around in the wind.

In simple terms, the colder it is when snow forms, the more volume there is.  So not only is there more snow when it's cold, the colder it is, the more snow there can be.
