Abstract

The analysis increment vertical interpolation scheme with the help of p-η coordinate transformation in T63 data assimilation system in NMC, SMA is described and the comparison results of control test with the ordinary interpolation scheme are presented. It is shown that increment scheme can reduce vertical interpolation error and provide better initial values. Therefore, it plays an important role in improving data assimilation and model forecasting.
