Abstract: Based on the spectral representation of zero-mean stationary process, another method of fitting the target power spectrum is obtained. The fitted random sequence is uniformly convergent with respect to the target sequence. Compared to the commonly used wave superposition method in simulating wind velocity fluctuations, its merits and deficiencies are shown.

Keywords: turbulent wind velocity sequence; stationary process; fitted power spectrum; wave superposition method.
