Abstract

With incremental form of three-dimensional variational (3D-Var) method as data assimilation method and the MM5 mesoscale model as both assimilation and prediction model, NOAMSUA experiment, where only radiosonde observations were assimilated, was in comparison with AMSUA experiment, where radiosonde observations and AMSU-A channel brightness temperatures were assimilated simultaneously. The comparison results show that direct assimilating AMSU-A data has a positive impact on model prediction as a whole.
