• Wind data at 290 points widely distributed in domestic potential wind farm sites were assessed in view of turbulence with regards to Turbulence model (NTM) in IEC91400-1Ed.3. While observed mean 15m/s turbulence intensity exceeded NTM cat.A value(=0.16) only at 20% of the investigated sites, observed 90% quantile exceeded NTM cat.A representative value at 48% of the sites. This discrepancy in the NTM coverage between mean and 90% quantile mainly comes from the fact that estimation of variance of σ in NTM is far below observation. Some idea of modification to NTM model to adequately describe the observation is presented.
