摘　　要：文章简单地介绍了国家气象中心Ｔ６３四维资料同化系统试验方案及试验的初步结果。试验结果表明，该系统计算稳定，是一个较好的同化方案；Ｔ６３Ｌ１６中期数值天气预报谱模式利用它提供的初始条件制作了７天全球预报，预报结果优于Ｔ４２Ｌ９业务系统。This paper describes an experimental scheme of the four-dimensional dataassimilation system in NMC and its experimental results. The resuIts indicate that thisassimilation scheme is stable on computation. Using the initial condition provided by thescheme,the 7- day global forecasts were produced by T63L1 6 medium-range numericalweather prediction spectral model.Comparison of T63L16 prediction system withT42L9 operational one shows that T63 is better than T42.
