Snow that persists into summer evolves into névé, granular snow, which has been partially melted, refrozen and compacted. Névé has a minimum density of 500 kilograms per cubic metre (31 lb/cu ft), which is roughly half of the density of liquid water. [56]
Snow density (ρ s) is the mass per unit volume of snow of a known volume, calculated as kg/m 3. Classification runs from very fine at below 0.2 mm to very coarse (2.0–5.0 mm) and beyond. Snow hardness (R) is the resistance to penetration of an object into snow. Most snow studies use a fist or fingers for softer snows (very soft through ...

The weight of snow can vary dramatically: A cubic foot of dry, powdery snow might weigh 3 pounds, while a cubic foot of heavy, wet snow can weigh as much as 10 pounds. −Doyle Rice.
Pillow drift – A pillow drift is a snow drift crossing a roadway and usually 3 to 4.5 metres (10–15 feet) in width and 30 cm to 90 cm (1–3 feet) in depth. [ 28 ] Sastrugi – Sastrugi are snow surface features sculpted by wind into ridges and grooves up to 3 meters high, [ 29 ] with the ridges facing into the prevailing wind.
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
In Ohio's Ashtabula County, which borders Lake Erie 50 miles northeast of Cleveland, one town was hit with almost five feet of snow. Saybrook, population 10,000, recorded more than 56 inches of snow.
is the air density in the duct (pounds per cubic foot), is the standard air density (0.075 pound per cubic foot), is the resistance (atkinsons), is the rate of flow of air (thousands of cubic feet per second).
