摘要

PROBLEM TO BE SOLVED: To read estimates of wind speeds in different directions at a desired point. SOLUTION: The measurements of wind speeds in different directions at each of a plurality of measuring points are statistically processed to determine the basic wind speeds in different directions at each measuring point. Also, simulations or experiments reflecting the influence of geography between the measuring points are conducted to determine virtual measurements of wind speeds in different directions at and between the measuring points. The virtual measurements are corrected to make the basic wind speeds equal to the virtual measurements at all the measuring points so as to determine estimated basic wind speeds in different directions between the measuring points. Using the estimated wind speeds and the basic wind speeds in different directions, adjacent equal values or values belonging to a certain numerical range are connected by lines, whereby isotachs of estimated basic wind speeds in different directions are drawn on a map.
