The spelling of the phrase "blowing snow" is quite straightforward. The word "blowing" is spelled with a "b," a "l," an "ow" sound (represented by the phonetic symbol /oʊ/), an "i," an "ng," and a final "g." Meanwhile, the word "snow" is spelled with an "s," an "n," an "ow" sound (also represented by /oʊ/), and a final "w." Together, the two words describe a snowstorm in which the snow is being blown about by the wind, creating a hazardous and often eerie atmosphere.
Blowing snow refers to a meteorological phenomenon that occurs when loose, dry snow is lifted from the ground surface by the wind. It involves the suspension and movement of snow particles, creating a fog-like appearance and reducing visibility. This phenomenon usually occurs in cold climates characterized by high wind speeds and the presence of powdery or light snow.
Blowing snow can be triggered by strong winds, typically above 30 kilometers per hour, which are able to scoop up loose snow from the ground. As the wind lifts the snow particles, they are carried through the air, causing a turbulent and swirly effect. The particles can be blown to various heights, ranging from a few meters to tens or even hundreds of meters above the surface, depending on wind strength.
The resulting blowing snow can obscure the surrounding environment, making it difficult for individuals to see and navigate their surroundings. This can pose significant challenges for drivers, pilots, and pedestrians, as it reduces visibility and increases the risk of accidents.
Blowing snow is often associated with blizzard conditions, where strong winds and heavy snowfall combine to create hazardous weather conditions. These conditions can lead to snowdrifts and make travel nearly impossible due to reduced visibility and snow accumulation. Blowing snow is a common occurrence in regions with vast snow-covered landscapes such as polar areas, arctic regions, and high-altitude mountainous regions.
The word "blowing" in this context comes from the verb "blow", which originated from the Old English word "blāwan". "Blāwan" referred to the act of producing a current of air, either naturally or artificially. Over time, this verb extended its meaning to include the movement of air and related phenomena such as gusts or blasts.
The word "snow" has its roots in the Old English word "snāw". This word has Germanic origins and shares its origins with similar words in other Germanic languages. It evolved from the Proto-Germanic word "*snaiwaz" to "snāw" in Old English.
Therefore, when combined, "blowing snow" refers to the action of snow being moved or carried by the wind.
