While indirect assimilation experiment is better than that of non-assimilation one in rainfall center, the former appears positive role.2 Radar observations direct assimilation experiments: By means of ARPS-3DVar and ADAS (ARPS Data Analysis/Assimilation System), CINRAD observations are assimilated only with NCEP reanalysis data for the forecast of rainstorm. Results show that meteorological element fields are improved observably by assimilation experiments.
但同化实验对于主要降水中心的反映仍然比非同化实验好得多,对于初始场调整、模式预报仍然起到了积极作用。2雷达资料直接同化方面:以夏季暴雨为研究对象,在仅有NCEP资料的情况下,通过ARPS-3DVar和ADAS同化系统直接同化多普勒雷达资料可以对气象要素场产生显著影响和改善。

Furthermore data assimilation experiments are conducted with MM5 Adjoint-model Assimilation System made by adjoint codes. With a case of heavy rainfall taking place from 00h July 23 to 00h July 24,2002, several numerical simulation experiments of different schemes are performed. The results are as follows. MM5 Adjoint-model Assimilation System not only can improve the initial field effectively and promote the coordination with the model but also can enhance the forecast on the precipitation and other elements. The assimilation of CDW has an improvement on quality of upper wind. The effect of direct numerical simulation with utilizing the CDW to amend the initial field gains the advantage over the one not.
