| Abstract: | 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. |
