Impact of Multivariate Background Error Covariance on the WRF-3DVAR Assimilation for the Yellow Sea Fog Modeling

Figure 10

Analysis fields of temperature (color shades), wind (vectors), and mixing ratio (contours) at the lowest model level after three DA updates: (a)–(c) for CV5 and (d)–(f) for CV6. The bold lines indicate mixing ratio of 5.5 g/kg.
