Wind erosion climatic erosivity
Climatic Change, 1986A physically based wind-erosion climatic factor has been derived: $$CE = \rho \int {[u^2 } - (u_T^2 + \gamma ^l /\rho a^2 )]^{3/2} f(u)du$$ where ϱ is the air density, a is a constant made up of other constants (von Karman, height of wind speed observation ...

The quantity of soil material transported by wind will decrease with height above the surface. Airborne samples were obtained at five levels above four soils. Mass distribution with height differs for materials in saltation or in suspension. A technique was developed to mathematically describe the two modes of transport so the total quantity being ...

Wind velocities are often nonstationary with an almost cyclical repetition of strong gusts followed by relative calmness. It was demonstrated that the effects of nonstationary wind velocity on soil erosion are significant, and that a transient model is necessary to estimate rates of wind erosion. /Author/

Wind erosion is a serious problem in many parts of the world. It physically removes from the field the most fertile portion of the soil, pollutes the air, fills road ditches, reduces seedling survival and growth, lowers the marketability of many vegetable crops, and creates new desert landforms and landscapes.

Winds is an important erosive force in deserts, and in recent years there has been a re-appraisal of its power, notably with respect to the development of yardangs, inverted relief, desert depressions and dust storms. This paper provides a review of each of these phenomena.
