Background error covariance (BEC) plays a key role in variational data assimilation systems. The National Meteorological Center (NMC) method has been used widely to generate forecast error samples for BEC estimation. At present, most variational-based rapid update and cycling (RUC) data assimilation and forecasting systems use a fixed BEC withou...

Variational Assimilation of Cloud Liquid/Ice Water Path and its Impact on NWP
Analysis of the cloud components in numerical weather prediction models using advanced data assimilation techniques has been a prime topic in recent years. In this research, the variational data assimilation (DA) system for the Weather Research and Forecasting (WRF) model (WRFDA) is further developed to assimilate satellite cloud products that w...
