Particle lifting at the soil-air interface by atmospheric pressure excursions in dust devils

  title={Particle lifting at the soil-air interface by atmospheric pressure excursions in dust devils},
  author={Matthew Balme and Axel Hagermann},
[1] Dust devils, small-scale convective vortices found on Earth and on Mars, can transfer substantial quantities of dust from the ground into the atmosphere. It has been proposed that the low-pressure region found at the center of dust devil vortices provides a lift (the ‘DP’ effect) that ‘sucks up’ material from the surface. Two simple models are compared to investigate the physics behind the DP effect and the relevance of competing processes. The first considers an impermeable bed of… CONTINUE READING
