Impact forecasts are defined differently by various countries and institutions but have a common meaning of “reducing the risk of weather disasters by predicting accompanying damage to socioeconomic factors". Weather forecasts and special reports provided by domestic and foreign weather institutions in Korea are centred on the physical characteristics of weather phenomena; therefore, public and disaster agencies seldom recognise the degree to which such events could affect people's safety and property (World Meteorological Organization (WMO), 2015). Currently, The Korea Meteorological Administration promotes the development of 'impact forecast' technology to support disaster response decisions by providing impact information that incorporates the social and economic effects of weather. However, this organisation does not officially provide typhoon impact forecasting services. When predicting the impact of a typhoon, it is critical to maximise disaster prevention by estimating what extreme weather may occur during the actual invasion of the typhoon and providing such information in advance. In other words, detailed risk information for typhoons should be calculated accurately and quickly.
The WMO recommends and establishes guidelines for weather impact forecasts as a countermeasure against the damage caused by weather disasters, which has increased despite improved forecast accuracy. In addition, according to a presentation by the Korea Meteorological Association (2016), impact forecasting of typhoons has the highest economic value among many natural disasters. However, very little research has been conducted into predicting typhoon impacts in Korea and practical levels of results, so it is not helpful for typhoon pre-disaster activities at actual sites. Therefore, this study investigates the current status and cases of typhoon impact forecasting abroad, and proposes a typhoon impact forecast applicable to the Korean Peninsula, to establish a basis for typhoon impact forecasting in this region. and We would like to propose a Typhoon-Ready System for forecasting the impact of typhoons applicable to typhoons affecting the Korean Peninsula.
