FISHER-SHANNON ANALYSIS OF WIND RECORDS

The informational properties of hourly wind data measured in one site in northern Italy from April 1996 to December 2007 were investigated. The data were recorded by a Sodar Rass system, which measures the speed and the direction of the wind at several heights above the ground level. The Fisher-Shannon method was applied to allow discriminating dynamical features in complex time series. The findings point out to height-dependent informational properties of the wind speed. The obtained results shed light on a new perspective which contributes to a better understanding of the complex dynamics of wind phenomenon.
