摘要：

The application of radar–derived TREC wind to 3DVAR assimilation system of GRAPeS-3DVardeveloped by Chinese Academy of Meteorological Sciences is introduced. The resulting fundamental feature isestimated when radar TREC wind is assimilated into GRAPeS-3DVar system. It was found that radar TRECwind has better potential of the application in GRAPeS-3DVar system and can effectively improve the analyzedresults. Moreover a numerical experiment is performed in which tropical cyclones make landfall and transform;it also showed that the predicted effect can be improved when the radar TREC wind is added into GRAPeS-3DVar system.
