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. 6 5 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. The impact of numerical methods is investigated on the strength, frequency and structure of dust devils in a high resolution large-eddy simulation. Analyesd numerical methods are the calculation of perturbation pressure and different advection schemes (''Piacsek and Williams'' (1970) and ''Wicker and Skamarock'' (2002)). 7 6 8 7 '''Download:''' soon (in German)\\
