| Abstract: | Wind measurementsnear the North Seaborder of Northern Germany andvelocity measurements under localisotropic conditions of a turbulent wakebehind a cylinder are compared. It is shownthat wind gusts, measured by means ofvelocity increments, do show similar statisticsto the laboratory data if they are conditionedon an averaged wind speed value.Clear differences between the laboratory dataand the atmospheric measurements arefound for the waiting time statistics betweensuccessive gusts above acertain threshold. |
