In order to understand ocean eddies from the large volume data produced by simulations, visualizing only eddy distribution at each time step is insufficient; time-variations in eddy events and phenomena must also be considered. However, existing methods cannot precisely find and track eddy events such as amalgamation and bifurcation. In this study, we propose an original approach for eddy detection, tracking, and event visualization based on an eddy classification system. The proposed method detects streams and currents as well as eddies, and it classifies discovered eddies into several categories using the additional stream and current information. By tracking how the classified eddies vary over time, detecting events such as eddy amalgamation and bifurcation as well as the interaction between eddies and ocean currents becomes achievable. We adopt the proposed method for two ocean areas in which strong ocean currents exist as case studies. We visualize the detected eddies and events in a time series of images, allowing us to acquire an intuitive understanding of a region of interest concealed in a high-resolution data set. Furthermore, our proposed method succeeded in clarifying the occurrence place and seasonality of each type of eddy event. <\/jats:p>","DOI":"10.1142\/s1793962319500181","type":"journal-article","created":{"date-parts":[[2019,5,21]],"date-time":"2019-05-21T10:12:01Z","timestamp":1558433521000},"page":"1950018","source":"Crossref","is-referenced-by-count":4,"title":["Event detection and visualization of ocean eddies simulated by ocean general circulation model"],"prefix":"10.1142","volume":"10","author":[{"given":"Daisuke","family":"Matsuoka","sequence":"first","affiliation":[{"name":"Information Engineering Program, Research Institute for Value-Added-Information Generation, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), 3173-25 Showa-machi, Kanazawa-ku, Yokohama 236-0001, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumiaki","family":"Araki","sequence":"additional","affiliation":[{"name":"Information Engineering Program, Research Institute for Value-Added-Information Generation, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), 3173-25 Showa-machi, Kanazawa-ku, Yokohama 236-0001, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideharu","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Application Laboratory (APL), Research Institute for Value-Added-Information Generation, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), 3173-25 Showa-machi, Kanazawa-ku, Yokohama 236-0001, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2019,7,2]]},"reference":[{"key":"S1793962319500181BIB001","doi-asserted-by":"publisher","DOI":"10.1029\/177GM03"},{"key":"S1793962319500181BIB002","doi-asserted-by":"publisher","DOI":"10.1029\/2003GL018532"},{"key":"S1793962319500181BIB003","doi-asserted-by":"publisher","DOI":"10.1029\/2005GL024633"},{"key":"S1793962319500181BIB004","first-page":"35","volume":"1","author":"Masumoto Y.","year":"2004","journal-title":"J.
