1. A method of calculating a return period wind speed for a proposed wind turbine site, the method comprising:
providing wind speed measurements associated with the proposed wind turbine site, the wind speed measurements measured during a measurement period;
transforming the wind speed measurements into a frequency domain to generate a measured wind speed spectrum;
providing modelled wind speeds, wherein the modelled wind speeds are estimates of wind speeds at the proposed wind turbine site during an extended period, the extended period being longer than the measurement period;
transforming the modelled wind speeds into the frequency domain to generate a modelled wind speed spectrum;
combining the measured wind speed spectrum and the modelled wind speed spectrum to generate a hybrid spectrum;
transforming the hybrid spectrum from the frequency domain into a time domain to provide hybrid wind speed measurements; and
calculating the return period wind speed using the hybrid wind speed measurements.
