Abstract:
Wind measurement is important for estimating wind energy potential but relatively cost-intensive and often
conducted at a narrow height near or not far from the ground at the typical range of most wind hub heights in current wind
turbine technology is 30-50 m (or even higher). Extrapolation on wind data thus becomes necessary to estimate wind speed at
a high altitude. Doing so requires the essential understanding of wind shear characteristics representative to a location or a
region. The analysis is carried out from the profile of meteorological data collected from 50m tower at Sathyabama University
during the year 2010-2014. The tower is located near the coastal region in Chennai. The tower is equipped with instruments
to measure several meteorological variables. For wind speed and direction, they are routinely measured at different heights,
which are considered well suitable for wind shear characterization. In this work, the characteristics of wind shear exponent at
the tower were investigated and discussed, with emphasis on temporal (diurnal and monthly) variation and occurrence
distribution.
