Wind Turbulence (I_v(z)): Section 4.4

Wind turbulence intensity, I_v, at height z is calculated according to the following equation:

I_{v} (z) = \{\begin{matrix} \frac{k_{l}}{c_{o} (z) l n (\frac{z}{z_{0}})} z_{m i n} \leq z \leq z_{m a x} \\ I_{v} (z_{m i n}) z \leq z_{m i n} \end{matrix}

(4.7)

where

k_l	=	turbulence factor (user-defined)
z_min	=	the minimum height defined in Table 4.1
z_max	=	the maximum height (taken as 200 m)
