Abstract
ABSTRACT Wind erosion is the main problem that arid lands in northern Mexico are facing. Quantification of this phenomenon is crucial for planning purposes and to scale its impact. The challenge is to assess the problem under limited availability of climatic information. This study aimed to identify potential areas of dust emissions in an arid zone of Northern Mexico. Wind direction and intensity were characterized through a robust index that involves rainfall and evaporation as well as the climatic factor [...]

This study aimed to identify potential areas of dust emissions in an arid zone of Northern Mexico
Wind direction and intensity were characterized through a robust index that involves rainfall and evaporation as well as the climatic factor of the general wind erosion equation
Dust storms originate from the uplift of dust into the atmosphere resulting from the complex interaction of moving airflows and soil particles on the ground (Gherboudj et al, 2017)
Summary
Dust storms originate from the uplift of dust into the atmosphere resulting from the complex interaction of moving airflows and soil particles on the ground (Gherboudj et al, 2017). Their frequency has been on the rise during the last decade, and forecasts suggest that their incidence will increase as a response to climate change and anthropogenic activities (Schweitzer et al, 2018). When the ground is covered by vegetation, it provides a barrier to uplift soil particles, reducing wind erosion and the quantity of dust emitted. Among the effects of dust storms are loss of soil, organic matter, and nutrients, which decrease agricultural productivity, damage to young crop plants, reduced visibility, which affects aircraft and road transportation, and effects on human health (Gerivani et al, 2011)
