Although a wind speed in ground-based observation is strongly influenced by a surrounding terrain, measurement of atmospheric pressure is not thought so. A local wind suitably estimated using observed pressure data is useful for the investigation and prediction of wind disaster. In this paper, we compared ground-based observed wind speed with the corresponding wind speed estimated using the barometric pressure gradients which is based on measured pressure data when Typhoon Chaba(0416), Songda(0418) and ShanShan(0613) passed. Although reductions to mean sea level of the measured pressures were mostly distributed on concentric circles agreeing with values guessed using a formula of Schloemer, the projected wind speeds overestimated the mean wind ground-based. However we could approximately estimate maximum values and their areas where wind speeds became the largest.
