Wind power developers measure actual wind resources, in pan to determine the distribution of wind speeds because of its
considerable influence on wind potential.
The Weibull wind speed distribution is a mathematical idealization of the distribution of wind speed over time.
The function shows the probability of the wind speed being in a lm/s interval centered on a particular wind speed .
Taking into account both seasonal and annual variations for the years covered by the statistics.
The Weibull distribution function is'given by:
where F(V) is the ftaction of time for which the hourly mean wind speed exceeds V.
It is characterized by two parameters, a 'scale parameter' C and
