    Statistical Distribution of Atmospheric Dust Devils on Earth and Mars

    The theoretical foundations of the exponential and power-law analytical formulations for the size–frequency and intensity–frequency distributions of the convective vortices, including dust devils, are re-exami...

    Turbulent Helicity in the Atmospheric Boundary Layer

    We consider the assumption postulated by Deusebio and Lindborg (J Fluid Mech 755:654–671, 2014) that the helicity injected into the Ekman boundary layer undergoes a cascade, with preservation of its sign (right- ...

    Dust Devil Steady-State Structure from a Fluid Dynamics Perspective

    Simple analytical models for the flow structure of dust devils in steady state, and a “thermophysical” scaling theory that explains how these flow structures are maintained are reviewed. Then, results from hig...

    History and Applications of Dust Devil Studies

    Studies of dust devils, and their impact on society, are reviewed. Dust devils have been noted since antiquity, and have been documented in many countries, as well as on the planet Mars. As time-variable vorte...

    Non-ENSO interannual rainfall variability in central Chile during austral winter

    The first principal component (PC1) of seasonal rainfall anomalies in central Chile during winter (June–August) is used to analyze the circulation anomalies related to wet and dry conditions, when near-normal ...

    Micrometeorological Conditions for Dust-Devil Occurrence in the Atacama Desert

    We report on field observations in January 2009 (austral summer) of atmospheric dust devils in the northern part of the Atacama Desert in South America (≈20◦S). An extremely high level of dust-devil activity over...
