Dust storms are atmospheric phenomena in which strong winds entrain and transport large quantities of loose, fine-grained mineral particles (primarily silt- and clay-sized) from arid or semi-arid surfaces into the boundary layer and sometimes higher troposphere. They are driven by pressure gradients associated with synoptic systems, convective outflows, or frontal passages, and are characterized by reduced visibility, intense horizontal fluxes of particulate matter, and strong size-selective sorting. Research on dust storms examines their emission thresholds, aerodynamic entrainment mechanisms (saltation and suspension), radiative and microphysical impacts on climate, nutrient and contaminant redistribution, and implications for atmospheric chemistry and human and ecosystem health.
For five years now, a distinctive green laser beam has been shining at night up to 30 kilometers (19 miles) above the harbor of the island's capital. It forms part of a high-energy lidar with which the Leibniz Institute for ...

In recent years, residents of Spain, France and the UK have looked up to see an eerie sight: deep orange sunrises and skies thick with a yellowish haze. These hazy skies often deposit "blood rain," rust-colored precipitation ...

The technology used to predict sand and dust storm (SDS) severity has for decades systematically overestimated when and where sediment is transported across Earth's surface, a new study shows. Existing models, which draw ...

When Saharan dust reaches the UK and Europe, as a huge country-sized cloud did over the past few days, it can transform the sky. Tiny particles drifting in the atmosphere scatter blue light while allowing reds and oranges ...

Most people can imagine why a shrinking Great Salt Lake would mean unhealthy dust storms for the Wasatch Front, or why refilling the lake through water conservation could reduce dust exposure. Now, there is a data-based modeling ...

Mars is a dusty planet dominated by vast, dry deserts, with no easily accessible sources of liquid water. Much like on Earth, dust is lifted from Mars's surface by wind and rotating air columns, transported through the atmosphere, ...
