    A preliminary assessment of the spatial and temporal patterns of sand and dust storms over the Sahara by Sahar A. Saleh, Saleh A․ S․, Hesham Badawy

    Published 2025-06-01
    “…The results also reveal a statistically significant long-term reduction in SDS frequency, intensity, and duration, ascribed to enhanced Sahelian vegetation, diminishing wind patterns, and changing climate oscillations. In contrast, winter exhibited an increase in SDS activity, perhaps influenced by synoptic-scale meteorological phenomena such as high-pressure anomalies. …”
