  In this paper, the time dynamics of the daily means of wind speed measured in
complex mountainous regions are investigated. For 293 measuring stations
distributed over all Switzerland, the Fisher information measure and the
Shannon entropy power are calculated. The results reveal a clear relationship
between the computed measures and both the elevation of the wind stations and
the slope of the measuring sites. In particular, the Shannon entropy power and
the Fisher information measure have their highest (respectively lowest) values
in the Alps, where the time dynamics of wind speed follows a more disordered
pattern. The spatial mapping of the calculated quantities allows the
identification of two regions, which is in agreement with the topography of the
Swiss territory. The present study could contribute to a better
characterization of the temporal dynamics of wind speed in complex mountainous
terrain.
