摘要

The quasi-geostrophic 3D-Var data assimilation simulation system is developed to compare several methods for data assimilation and ensemble forecasting. The analysis and the forecast errors of the day obtained from 3D-Var are compared with bred vectors (BV) and singular vectors (SV). The final SVs have a similar structure as the BVs and both of them have the ability to depict the shape of the background error. The initial SVs are dominated by the zonal patterns with a strong meridional gradient.
