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 ...
Snow hydrology is quite complex and involves both mass and energy balance calculations over a time-varying snow pack which is influenced by spatial location in the watershed, interaction with vegetation and redistribution by winds. Some researchers seek to accurately capture snow dynamics at a point and over a domain as the spatial pattern of ...
Lake-effect snow is virtually unheard of in Detroit, Toledo, Milwaukee, Toronto, and Chicago, because the region's dominant winds are from the northwest, making them upwind from their respective Great Lakes, although they, too, have on extremely rare occasion seen small amounts of lake-effect snow during easterly or northeasterly winds.

By RYAN GORMAN Scientists now believe that global warming is to blame for extreme cold snaps in North America during the winter months – and that it will only keep happening. The "polar ...
Snow is an important consideration for loads on structures. To address these, European countries employ Eurocode 1: Actions on structures - Part 1-3: General actions - Snow loads. [85] In North America, ASCE Minimum Design Loads for Buildings and Other Structures gives guidance on snow loads. [86]
Snowfall so far this season in the U.S. has varied from feet of snow for some to an unusual lack for others in the East, Midwest and West. The national overview: The map below from NOAA shows an ...
The western part of the contiguous United States west of the 98th meridian, the mountains of the Pacific Northwest, the Willamette Valley, and the Sierra Nevada range are the wetter portions of the nation, with average rainfall exceeding 30 inches (760 mm) per year. The drier areas are the Desert Southwest, Great Basin, valleys of northeast ...
