Outline of Final Research Achievements

ENSO is a global phenomenon where the sea water in tropical pacific warms or cools in comparison to normal years. ENSO strongly affects not only climate and weather, but also the upper atmosphere above 400 km, as revealed by our analysis of 46 year's satellite observation data. Through numerical simulations using the GAIA model, the physical process underlying the vertical coupling process has been largely clarified. However, the role of Ozone in this coupling remains unclear and needs further investigation.
