Most of the damage caused by typhoons occur due to the strong wind and heavy rain it brings, In order to predict and prepare for the possibility of damage in advance, fast provision and accuracy of information on the spatiotemporal characteristic of wind and heavy rain during a typhoon are required. Due to geographical and topographical complexity, wind strength appears to vary regionally even in a narrow spatial area on the Korean peninsula, so it is very important to set detailed regional standards for strong wind risk. Therefore, in this study, the regional strong wind risk information of the KMA (Korea Meteorological Administration), which set the whole country as the same standard value, and the regional strong wind risk information in detail considering the detailed regional strong wind characteristics were compared and analyzed. In addition, the 'maximum damage' for a region was calculated based on the strong wind risk of the typhoon impact assessment customized for the Korean Peninsula, again considering regional characteristics. Furthermore, an objective database was established as advance disaster prevention information that can be used in the actual fields. As a trial basis, the period of typhoon impact on the Korean peninsula from 2002 to 2019 was set as the research period, and the study was conducted in Seoul (west coast) and in Busan (southeast coast). If the research methods and results of this study are applied in the field, it can be an effective data for typhoon impact assessment considering regional characteristics.
