Wind roses are tools used to display the direction of the prevailing wind. Knowledge of the prevailing wind allows the development of prevention strategies for wind erosion of agricultural land, such as across the Great Plains. Sand dunes can orient themselves perpendicular to the prevailing wind direction in coastal and desert locations ...
The desert's arid environment causes the soil to become fine and easily lifted by strong winds, such as those associated with the Harmattan or the trade winds. These winds can lift millions of tons of sand and dust into the atmosphere, creating a dense, suspended cloud that can travel thousands of kilometers. [4]
Buran (a wind which blows across eastern Asia. It is also known as Purga when over the tundra); Karakaze (strong cold mountain wind from Gunma Prefecture in Japan); East Asian Monsoon, known in Korea as jangma (), and in Japan as tsuyu (梅雨) when advancing northwards in the spring and shurin (秋霖) when retreating southwards in autumn.
These dune fields are formed by the prevailing wind from the northwest dropping sand particles in the lee of the Sierra Samalayuca (Samalayuca Mountains). Besides the high dunes appearing in the area of the village of Samalayuca, the dune fields lie in several other areas of the Samalayuca desert to the southwest and southeast of Ciudad Juárez.
These belts are associated with the subtropical anticyclone and the large-scale descent of dry air. The Sahara Desert is of this type. Mid-latitude deserts occur between 30° and 50° North and South. They are mostly in areas remote from the sea where most of the moisture has already precipitated from the prevailing winds.
Fixed crescentic dunes that form on the leeward margins of playas and river valleys in arid and semiarid regions in response to the direction (s) of prevailing winds, are known as lunettes, source-bordering dunes, bourrelets and clay dunes. They may be composed of clay, silt, sand, or gypsum, eroded from the basin floor or shore, transported up ...
To form the Santa Ana winds, the typical first ingredient is a chilled autumn day in the high desert of southern Nevada. The chill creates cold, dense air, which is squeezed from aloft by a high ...
Wind erosion of soil at the foot of Chimborazo, Ecuador Rock carved by drifting sand below Fortification Rock in Arizona (Photo by Timothy H. O'Sullivan, USGS, 1871). Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets).
