The coverage and quality of AMVWV (Atmospheric Motion VectorsWater Vapor) are discussed. To verify the AMVWV impaction, the quasioperational edition GRAPES_GFS_1423 is used to carry out a onemonth test. The AMVWV observations come from the database of the National Meteorological Information Center (NMIC). The results indicate that AMVWV data distribute above 700 hPa, and the observation errors of the AMVWV with QI above 80% can compare with that of AMVIR. The assimilation of AMVWV can improve the analysis of the wind from 500 hPa to 100 hPa. The RMS of the wind analysis is reduced slightly. The anomaly correlation coefficient of the 500 hPa height for 144hour forecast is enhanced by 0.02. The data quality of AMVWV in the clear sky above 700 hPa is relatively poor. The third experiment does not have much improvement in analysis and forecast.
