A Framework for Four-Dimensional Variational Data Assimilation Based on Machine Learning

A Framework for Four-Dimensional Variational Data Assimilation Based on Machine Learning

The initial field has a crucial influence on numerical weather prediction (NWP). Data assimilation (DA) is a reliable method to obtain the initial field of the forecast model. At the same time, data are the carriers of information. Observational data are a concrete representation of information. DA...
