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.展开更多
