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

Figure 18

Boundaries of the forecasted sea fog area for Exp-B_CV5 (red lines) and Exp-B_CV5e (blue lines) (upper row) and for Exp-B_CV6 (red lines) and Exp-B_CV6e (blue lines) (lower row). The number in each panel is the enlargement rate (%) of sea fog area produced by Exp-B_CV#e compared to that by Exp-B_CV#.
