The impact forecast is a more advanced forecasting system in that it provides direct information on how the weather changes will affect the safety of the people and the quality of life of the people while the existing weather forecasts focused on providing simple weather information. For the successful impact forecast, it is important to improve the accuracy and completeness of the probability prediction system. For this purpose, the probability distribution of the meteorological element was obtained by combining the three ensemble models and four single models utilized by the Korea Meteorological Administration. The distribution of meteorological element based on multiple model outputs is estimated using the hierarchical statistical model. It is expected to contribute to the prevention of risk of meteorological disasters and improvement of the life quality by constructing optimized multi-ensemble prediction system.
