Numerical impacts on the strength of simulated dust devils
Responsible: Fabian Hoffmann?
Project type: bachelor thesis
Duration: 29/08/2011-21/11/2011

The strength of simulated dust devils is smaller than observed values. Particularly, the pressure deviation from ambient is more than one order of magnitude too small. In a high resolution large-eddy simulation the impact of numerical methods (calculation of perturbation pressure, advection schemes according to Piacsek and Williams [1970] and Wicker and Skamarock [2002]) on the strength, frequency and structure of dust devils is investigated.
