Effect of Flow-Dependent Unbalanced Background Error Variances on Tropical Cyclone Forecasting

Effect of Flow-Dependent Unbalanced Background Error Variances on Tropical Cyclone Forecasting

The background error variance in variational data assimilation can significantly affect a model’s initial field. Around extreme weather events, the variance of the unbalanced control variables have contributed highly to the total variance. This study investigates the effect of flow-dependent unbalan...
