through a network of measurement stations located in the interest
places. The sensors were located in the measurement towers at
10 m above the ground level. Their characteristics are shown in
Table 1
The information generated by the sensors is accumulated in the
data acquisition systems through chips or memory cards that later
are unloaded in a computer for their processing.
The data acquisition measures the wind velocity every 1 s and
every 10 min the mean value was estimated. In total 52,560 wind
velocity data were measurement through the period
