| Abstract: |
| A four-dimensional variational data assimilation system is established to optimize the, initial fields of a hybrid air-sea coupled model. The prediction skill of tropical SSTA is improved. Statistical models for predicting annual TC frequency affecting East China area and Shanghai city are developed based on 37-yr products of this model and the forecast results are perfect in 1998 and 1999. |
| Key words: sea surface temperature anomalous four-dimensional variational data assimilation affecting tropical cyclone |
