Vertically Correlated Signals in Turbulent Windfields — •Thomas Laubrich and Holger Kantz — Max-Planck-Institut für Physik Komplexer Systeme, Nöthnitzer Str. 38, 01187 Dresden

The wind velocities at different points in the atmosphere are highly spatial correlated. The understanding of turbulent wind fields and its correlated structures plays an important role for atmospheric applications, e.g. the design of wind turbines. The focus is put on the exchange of spatial-temporal structures in the Prandtl Layer using data collected at a windmast with cup-anemometers installed at different altitudes. Examining the cross-correlation between the wind speeds at different altitudes helps us to gather information about the nature of highly correlated signals.
