Application of PFI-4DVar Data Assimilation Technique to Nowcasting of Numerical Model

Nowcasting is mainly based on radar echo or satellite image extrapolation method. However, the prediction ability of extrapolation method decreases with time, because this method cannot describe the physical mechanism during the occurrence, development and extinction of severe convective weather sys...
