In numerical weather prediction, the observation,prediction and data assimilation techniques have developed dramatically,achieving improvements of forecast skills of high-impact weather eventssuch as bomb cyclones, super typhoons, torrential rain, tornadoes andhot spells. Data assimilation techniques have been applied toatmospheric transport, ocean circulation and earthquakes and a number ofadvanced techniques have been proposed. In this session, with invitedspeaker Prof Emeritus Yoshikazu Sasaki, we review the recent developmentof data assimilation techniques, discuss methodologies and applicationsof their applications and project future directions for further development.
