| Abstract: | In 1990s, a four-dimensional variational Doppler radar analysis system (VDRAS) has been developed and implemented in NCAR. This analysis system applies the four-dimensional variational data assimilation technique to a cloud-scale model. VDRAS can be used to retrieve three-dimensional wind, temperature, pressure, and microphysical fields in convective storms by assimilating data from one or more Doppler radars. This paper aims at summarizing VDRAS' basic principle, cases study, and real-time running. With the accomplishment of China's new generation weather radar project step by step, this paper hopes to provide some references in 4D-VAR research and application using China CINRAD radar observations. |
