Project Details


This proposal requests funding to continue our research to conduct ocean data analyses and modeling for forecasting of the ocean state in the seas around Taiwan and China Seas, and also to gain a deeper understanding of the relevant processes. Progress has been made under the present project supported by MOST, during which a total of 13 SCI papers were published in International Journals (see references listed above). We have developed a data-assimilated Advanced Taiwan Ocean Prediction (ATOP; system at the National Central University, Taiwan. Each day, the ATOP system downloads satellite and in situ data, conducts initialization analysis using these data and model nowcasts, and then produces forecasts differing in initial perturbations and model parameters. Since March of 2012, the ATOP system has provided once-a-day, 7-day ensemble forecast of the three-dimensional ocean currents, salinity and temperatures, as well as of wind-generated waves, covering the entire North Pacific Ocean including the Taiwan Strait and the China Seas. The ATOP model and data are freely available to the community at large. In addition to the practical ocean predictions, our group has also conducted basic modeling and data-analysis research of circulation and climate physics spanning a wide range of processes from coastal to basin scales, and from daily to decadal time scales. Results from these activities have been reported in national and international conferences, as well as in several SCI publications. This proposal requests funding to continue research focusing in 2 areas: (1) implement the WRF atmospheric model to produce high-resolution forecast wind fields that will be used to drive the ATOP ocean model, to further improve ATOP forecast skills, and then conduct model-data comparison to quantify and validate model skills; and (2) to conduct modeling and data-analysis research focusing on inter-annual processes that govern the circulation of the China Seas, including the Taiwan Strait, and their coupled interaction with the open Pacific Ocean eddies and the Kuroshio. The proposed model developments and research are expected to produce and improve the quality of ocean products for practical applications by the community, as well as to advance our understanding of processes of the seas around Taiwan. We also envision that funding for these research activities will continue to support and cultivate students and young researchers in mathematical modeling and data analyses of oceanic, atmospheric, and climate processes.
