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

Figure 4

Geographic map of the two nesting domains of the weather research and forecasting (WRF) simulations for Case-A (a) and Case-B (b). Sites of surface (small dots) and upper-air (large dots) observations are indicated. The red dot in (a) is the observation location for single-observation experiments in Section 4.1, and the red dots in (b) are locations of upper-air observations for verification of Case-B.
