Major achievements

“Tomoki Tozuka has been analyzing observational and numerical modeling data and conducting numerical simulations to study ocean-atmosphere interactions from a novel viewpoint, and has made a series of discoveries that challenges established theories. For example, the discovery of the annual El Nino-Southern Oscillation (ENSO) has contributed to an understanding of the ENSO, and its findings have been highlighted by the Bulletin of the American Meteorological Society. He also pointed out that a small ocean current in the South China Sea affects a basin-scale phenomenon through heat transport in the Indonesian Seas, and this has had an impact even on paleoclimate studies. More recently, he has extended his research to the mid-latitudes and presented a novel atmosphere-ocean interaction process in a mid-latitude oceanic frontal region. He received the Okada Prize from the Oceanographic Society of Japan in his 20s, which is awarded to young scientists under the age of 36, and has continued to publish high-quality papers. He is currently an editor/associate editor of international journals such as Journal of Climate and a member of international scientific committees such as CLIVAR, and his achievements are highly appreciated both in Japan and overseas.
