Abstract

As a demonstration of big data assimilation to predict sudden downpours, this article describes data assimilation in leading meteorological research and provides its broader perspectives beyond meteorology. For the readership of “Applied Physics,” this article focuses on a concrete methodology for data assimilation from the viewpoint of complex models and applied physics. Data assimilation links large-scale complex models and actual data and provides a general methodology for syncing mathematical models and the real world. This article describes the background of numerical weather prediction, the role of data assimilation, and the perspectives to broaden applicability in various fields.
