WeSCoS Colloquium #10 “Study towards applying machine learning to numerical weather forecasting”
Presenter: Takumi Honda (Associate Professor, Information Technology Center, University of Tokyo)
Date and time: 3:00 pm-, August 6, 2024 (Tuesday)
Abstract:
Applications of machine learning are rapidly advancing in various fields, including numerical weather forecasting. In fact, some weather predictions made using machine learning models have achieved greater accuracy than traditional physical simulations. However, the approach of replacing all physical simulations included in numerical weather forecasts with machine learning models is currently not practical for on-site systems that require stable operation. Therefore, as a more conservative application of machine learning, we are proposing a new method that uses machine learning models only for quality control of observations [1]. This new method enables real-time estimation by using highly accurate predictions from machine learning as reference data when estimating the impact of observation assimilation on predictions. In this presentation, we would like to introduce a new method and discuss more proactive approaches, such as replacing the data assimilation process itself with machine learning.
