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

Figure 11

Observation innovations and analysis increments of the 3rd update at the lowest model level for CV5 (upper row) and CV6 (lower row): innovations of temperature (a, e) and mixing ratio (b, f); increments of mixing ratio with (c, g) and without (d, h) assimilation of temperature. The dots indicate the observational sites.
