Abstract

A method was proposed in the previous report in 1996 for the simulation of multidimensional wind fluctuations at some points adjacent to the points where wind fluctuations were observed. The method was based upon the auto-regressive processes and made use of the model defined by the space-time structures such as power spectra and cross spectra among the observed winds and those obtained by the simulation. As the simulation is founded on the statistical relations, the simulated wind fluctuations do not exactly agree with the actual ones at the reference point where the simulation is carried out. Some disagreement between these fluctuations is unavoidable in the case of the simulation based on the statistics . In this report a method for theoretically investigating the relations, expressed by co-coherence, between simulated and actual fluctuations at the same point is proposed. Some examples analyzed by the method are shown.
