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

<div>Locations of ship measurements (a) and biases of forecasted mixing ratio compared with observation (b) for Case-A. The improvements (%) of Exp-A_CV6 compared to Exp-A_CV5 are presented below the S# (identified mark of ship sites) along horizontal coordinates.</div>
