snow patch

relatively small area of snow cover remaining after the main snowmelt period.

snow load

the downward force on an object or structure caused by the weight of accumulated snow.

snow line

the minimum elevation of snow lying on the ground or glacier surface; the snow line at the end of an ablation season marks a glacier's current equilibrium line.

snow layer

a layer of ice crystals with similar size and shape.

snow grains

precipitation in the form of very small, white opaque ice particles; they resemble snow pellets but are more flattened and elongated, with a diameter less than 1 mm; the solid equivalent of drizzle.

snow flurry

snow that falls for short durations and which often changes in intensity; flurries usually produce little accumulation.

snow extent

the total land area covered by some amount of snow; typically reported in square kilometers.

snow depth

the combined total depth of both old and new snow on the ground.

snow density

the mass of snow per unit volume which is equal to the water content of snow divided by its depth.

snow cover

(1) in general, the accumulation of snow on the ground surface (2) the areal extent of snow-covered ground, usually expressed as percent of total area in a given region.
