The Electrification of Dust-Lofting Gust Fronts (‘Haboobs’) in the Sahel

摘要：

Two Doppler radars and a suite of auxiliary surface observations are used to document the electrical, aerosol and thermodynamic properties of dust-lofting gust fronts near Niamey, Niger during the AMMA (African Monsoon Multidisciplinary Analysis). Electrification with dominant negative polarity is a common behavior, consistent with earlier studies on dust devils in dry environments.
