Dust devils may roam hydrocarbon dunes on Saturn’s moon Titan
Smoggy, with a chance of dust devils: conditions at the surface of Saturn’s moon Titan may spawn convective whirlwinds By Liza Lester Meteorological conditions on Saturn’s large moon Titan, the strange, distant world that may be the most Earth-like in the solar system, appear conducive to the formation of dust devils, according to new research in AGU’s journal Geophysical Research Letters. If true, these dry whirlwinds may be primary movers …

Research finds spike in dust storms in American Southwest driven by ocean changes
People living in the American Southwest have experienced a dramatic increase in windblown dust storms in the last two decades, likely driven by large-scale changes in sea surface temperature in the Pacific Ocean drying the region’s soil, according to new NOAA-led research. With the increase in dust storms, scientists have also documented a spike in Valley fever, an infectious disease caught by inhaling a soil-dwelling fungus found primarily in the Southwest.

NASA Mars orbiters reveal seasonal dust storm pattern
For six recent Martian years, temperature records from NASA Mars orbiters reveal a pattern of three types of large regional dust storms occurring in sequence at about the same times each year during the southern hemisphere spring and summer. Each Martian year lasts about two Earth years.
