SASTRUGI Meaning and
Definition
-
Sastrugi refers to a natural phenomenon found in snowy and icy regions, particularly in polar environments. It is a term used in geography and meteorology to describe a series of sharp, linear, and parallel ridges or grooves that are formed on the surface due to the action of wind or erosion.
These formations occur when the wind blows across a snow-covered surface, causing the snow to be sculpted and shaped. As the wind encounters uneven surfaces, such as hills or obstacles, it creates turbulence and eddies, which result in the formation of sastrugi. The wind scours away the loose snow particles and accumulates them into elongated ridges and troughs, running parallel to the prevailing wind direction.
Sastrugi can vary in size, reaching heights of a few centimeters to several meters and can extend over long distances, covering vast areas of ice or snow. They can have irregular or smooth peaks, with sharp edges and steep sides. The shape and alignment of sastrugi formations provide insights into the direction, intensity, and duration of the prevailing winds, making them useful indicators for meteorologists and scientists studying polar climates.
While sastrugi can pose challenges for travelers, particularly skiers or snowboarders, who may find it difficult to navigate due to its uneven surface, they also create visually stunning landscapes. The ridges and grooves formed by sastrugi contribute to the unique textures seen in polar environments, adding to the beauty and interest of these extreme regions.

Etymology of SASTRUGI
The word "sastrugi" originates from the Russian language. It is a plural form of the Russian word "састроги" (sastrogi), which is derived from the verb "састрогать" (sastrogat'), meaning "to polish", "to roughen", or "to groove". The term was adopted into English, particularly within polar exploration, to refer to the parallel ridges or grooves formed on the surface of snow or ice by wind erosion.
