In this study, a new urban canopy model based on the porous media theory is proposed. Flow around two obstacles with different porosities, i.e., pine trees and a prism are simulated and compared with measurements. The simulated results showed a good agreement with measurements. The proposed model is applied to the estimation of wind speed during a typhoon to consider the effect of surrounding buildings around a meteorological station. Wind speed measured at Miyakojima Meteorological Station located in the urban area is converted to the wind speed at a distant site based on the result of the flow simulations with the proposed urban canopy model. Estimated wind speed showed a good agreement with measurements.
