| Outline of Final Research Achievements |
(1) This study clarified effects of observation data on ocean data assimilation results for some specific areas. For example, TAO/TRITON buoy data have large impacts in the western equatorial Pacific.
(2) This study clarified effects of observation data on El Nino forecasts using ocean data assimilation systems. For example, TAO/TRITON buoy data improves the accuracy by 3-7% and the effects increase with the lead time of the forecasts.
(3) This study clarified that the reduction of TAO/TRITON buoy data after 2012 affects El Nino forecasts by operational centers through intercomparison of operational analysis fields, and summarized results of researches on the importance of TAO/TRITON buoy data.
