A yardang is a streamlined protuberance carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion by dust and sand and deflation (the removal of loose material by wind turbulence). [1] .

雅丹地貌是新疆 罗布泊 地区的一种特殊的地貌形态，是一种典型的 风蚀 性地貌。 “雅丹”这一专业名词自斯文赫定（Sven Hed in）自1903年正式提出，并为地学工作者逐渐接受，进行研究以来，迄今已有百余年的历史。 [1] “雅丹”在 维吾尔语 中的意思是“具有陡壁的小山包”，该事件后来入选了《中国国家地理》杂志社与 中国地理学会 共同发起了“ 中国地理百年大发现 ”评选。 雅丹地貌现泛指干燥地区一种 风蚀地貌，河湖相土状沉积物所形成的地面，经 风化 作用、间歇性流水 …

yardang, large area of soft, poorly consolidated rock and bedrock surfaces that have been extensively grooved, fluted, and pitted by wind erosion. The rock is eroded into alternating ridges and furrows essentially parallel to the dominant wind direction.

2014年5月15日 · Yardangs are streamlined hills that are carved by wind erosion from bedrock. The rock must be sufficiently erodible for wind to either deflate (pick up) poorly-consolidated pieces or scrape...

2017年4月25日 · Yardangs are typically three times longer than they are wide when viewed from above. They form from generally soft surfaces that get eroded over time. The soft material gets carried away while the hard surface remains behind. They come in diverse shapes depending on the composition of the original material. Some even resemble human beings.

2023年10月22日 · A yardang is a long, narrow, and streamlined landform formed by the forces of wind and water erosion, typically found in dry or desert areas. These features often resemble ridges or hills, with their smooth surfaces sculpted over …

2015年11月20日 · A yardang is a fluted aerodynamic feature formed by eolian erosion. It is a wind-abraded elongated ridge-like sharp-crested landform with a steep and broader wind-faced front and a lower and narrower end (Besler 1992).

2025年2月12日 · Yardangs are ridges made of resistant rock which are developed and lie parallel to the direction of the prevailing wind. Wind abrasion produces another form of “ridge and furrow” landscape since the weak bands are readily eroded to leave the more resistant bands of hard rocks to stand as yardangs.

Yardangs are streamlined landforms that are shaped by the erosive forces of wind and typically found in arid or semi-arid environments. They often resemble elongated ridges or hills and are created through the process of aeolian erosion, where wind-carried particles wear away softer rock or sediment while leaving harder materials intact.
