Predictability and properties of turbulent wind gusts — •Detlef Holstein and Holger Kantz — MPIPKS, Noethnitzer Str. 38, 01187 Dresden

Dynamics in complex systems often contains long range memory. An information theoretical treatment aims for quantifying stochastic modelling of the dynamics behind time series data. As an application of our analysis an improvement of prediction of extreme events, especially of turbulent wind gusts in the atmospheric boundary layer is intended. Coherent structures in the turbulent boundary layer are analyzed for their impact on wind gusts.
