The salt, via freezing point depression, helps melt the snow and ice and also gives vehicles more traction. Later, usually when the snow has ceased falling, snow plows, front end loaders with snowplow attachments, and graders cover every street pushing snow to the side of the road. Salt trucks often then return to deal with any remaining ice ...
A snow blower or snowblower or snow thrower is a machine for removing snow from an area where it is problematic, such as a driveway, sidewalk, roadway, railroad track, ice rink, or runway. The commonly used term "snow blower" is a misnomer, as the snow is moved using an auger or impeller instead of being blown (by air). It can use either ...
A snow blower consists of a rapidly spinning auger which cuts through the snow, forcing it out of a funnel attached to the top of the blower. Snow blowers typically clear much faster than plows, with some clearing in excess of 5,000 tonnes (4,900 long tons; 5,500 short tons) of snow per hour, and can cut through far deeper snow drifts than a ...
Snow windrows are created by snow plows when clearing roads of snow; where this blocks driveways the windrow may require removal. Snow windrowed to the centre of the street can be removed by a snow blower and truck. In preparing a pond or lake for ice cutting, the snow on top of the ice, which slows freezing, might be scraped off and windrowed. [2]
Snowpack is an accumulation of snow that compresses with time and melts seasonally, often at high elevation or high latitude. [1] [2] Snowpacks are an important water resource that feed streams and rivers as they melt, sometimes leading to flooding. Snowpacks provide water to down-slope communities for drinking and agriculture. [3]

Wooden plows were carefully constructed of individually fitted boards and painted frequently to maintain a smooth surface. Steel plows can be sprayed with water in sub-freezing temperatures to form a smooth layer of ice on the plow surface. [2] The plow has a horizontal wedge to lift snow above the level of snow accumulation beside the track.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
