Different names for 'wind erosion'
Sometimes wind erosion can be called aeolian entrainment of soil; dust emissions from soil; summer erosion; grazing erosion; stocking erosion.
Wind erosion is the removal of soil sediments by the wind.
aeolian = relating to transport by wind
dust transport = the movement of dust across a distance, carried by the wind
long-range transport = refers to the transport of sediments across a great distance, such as being blown from a region of Australia across to New Zealand; or when dust is blown from the Sahara in Africa across to North America.
aeolian dust = dust picked up and transported by the wind
sediment transport = transport of sediments in the air
sediment deposition = the settling of sediments to the ground
saltation = the 'bouncing' of sediments along the ground (e.g. when sand blows along the beach on a windy day)
abrasion = the wearing of the surface by inter-particle contact during sediment transportation
dust event = dust in the air caused by a dust storm, dust haze, local blowing dust or dust devil. Dust haze signals a distant dust event.
How is wind erosion measured?
Researchers measure dust concentrations in the air, as well as where dust comes from, where it goes, and how easily it can be picked up by wind from loose soil. Common tools to measure dust are:
Anemometer – wind speed
Balance – weight
Barometer - air pressure
Compass – direction
Hygrometer – water vapour
Munsell chart – soil colour
Rain gauge – rainfall amount
Sieve – particle size
High volume sampler – collects dust from the air
Dust deposition trap – collects dust deposited from the air
Topics which scientists research about wind-blown dust are:
Dust transport processes
Dust deposition processes
Dust storms - how much dust, where they go, how they happen
Arid environments / deserts
Dust on Mars
Dust as a nutrient for ocean life
Health effects of dust storms
