Maximum wind speeds recorded at meteorological agency stations on the occasion of Typhoon 9119 were examined to estimate corresponding return periods. Stations within the distance of 300km from the eye path of the typhoon were chosen for this study. Prior to apply the Gumbel distribution to represent the probability distribution for annual maximum wind speeds, two cases for the correction were made, i.e., case 1 as the observation height correction based on a uniform power law profile and case 2 as the correction based on a power law profile varied with year from 1959 to 1970. Estimated return period values vary considerably for sites with the distance from the eye path within 150km. Such a variation seems to be caused by some local and topographical effects. The significance of the selected periods for return period estimation is also pointed out.
