| Abstract: |
| Three years' operational prediction results by the tropical cyclone track model of East China sea in 1996. 1997 and 1998 were counted in this paper. These results were compared with subjective forecast and Japan typhoon NWP on the same samples and the same time levels systematically. Experiment research were carried out on influencing tropical cyclone movement with the drag coefficient of planetary boundary layer physical process and twice typhoon bogus technique and three dimensional optimal interpolation objective analysis and data assimilation. And the operational running of intermittent data assimilation was achieved in 1998. |
