Typhoon Flo of 1990, which was observed in an intensive observation period of the Tropical Cyclone Motion Experiment-1990, was chosen for this study. The SSM/I retrieved rainfall rates within 888 km (80 latitude) of the storm center were incorporated into the initial fields by a reversed Kuo cumulus parameterization. This scheme is applied through two different assimilation methods. Five cases for which SSM/I overpasses were available were tested, including two cases before and three after Flo's recurvature. 收起
