Bo Huang-April 19- Convective Meteorology Seminar

Abstract: A uniform spatial localization for all scales is commonly applied in the ensemble-based data assimilation (DA) systems to treat sampling errors. Early studies suggest that the optimal effective localization length for the large scale is broader than that for the small scale.
