However, how global warming affects the structure of extremely intense tropical cyclones has not been thoroughly examined. This study defines extremely intense tropical cyclones as having a minimum central pressure below 900 hPa and investigates structural changes in the inner core and thereby changes in the intensity in the future climate. A 2-km mesh nonhydrostatic model (NHM2) is used to downscale the 20-km mesh atmospheric general circulation model projection forced with a control scenario and a scenario of twenty-first-century climate change. The eyewall region of extremely intense tropical cyclones simulated by NHM2 becomes relatively smaller and taller in the future climate. The intense near-surface inflow intrudes more inward toward the eye. The heights and the radii of the maximum wind speed significantly decrease and an intense updraft area extends from the lower level around the leading edge of thinner near-surface inflows, where the equivalent potential temperature substantially increases in the future climate. Emanuel’s potential intensity theory suggests that about half of the intensification (increase in central pressure fall) is explained by the changes in the atmospheric environments and sea surface temperature, while the remaining half needs to be explained by other processes. It is suggested that the structural change projected by NHM2, which is significant within a radius of 50 km, is playing an important role in the intensification of extremely intense tropical cyclones in simulations of the future climate.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420845751166588800","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"80727628"},{"@type":"NRID","@value":"1000080727628"},{"@type":"NRID","@value":"9000363498457"},{"@type":"NRID","@value":"9000283593372"},{"@type":"NRID","@value":"9000363408286"},{"@type":"NRID","@value":"9000257768329"},{"@type":"NRID","@value":"9000288832196"},{"@type":"NRID","@value":"9000270295474"},{"@type":"NRID","@value":"9000257767311"},{"@type":"NRID","@value":"9000363410504"},{"@type":"NRID","@value":"9000363409207"},{"@type":"NRID","@value":"9000016849182"},{"@type":"NRID","@value":"9000363490787"},{"@type":"NRID","@value":"9000363409373"},{"@type":"NRID","@value":"9000242878812"},{"@type":"NRID","@value":"9000363502473"},{"@type":"NRID","@value":"9000363408395"},{"@type":"NRID","@value":"9000405671319"},{"@type":"NRID","@value":"9000346923458"},{"@type":"NRID","@value":"9000363407911"},{"@type":"NRID","@value":"9000240187418"},{"@type":"NRID","@value":"9000257768314"},{"@type":"NRID","@value":"9000257768250"},{"@type":"NRID","@value":"9000258593581"},{"@type":"NRID","@value":"9000317130250"},{"@type":"NRID","@value":"9000363408590"},{"@type":"NRID","@value":"9000317130417"},{"@type":"NRID","@value":"9000242878811"},{"@type":"NRID","@value":"9000378103456"},{"@type":"NRID","@value":"9000363481800"},{"@type":"NRID","@value":"9000018916425"},{"@type":"NRID","@value":"9000363408730"},{"@type":"NRID","@value":"9000315141629"},{"@type":"NRID","@value":"9000363487590"},{"@type":"NRID","@value":"9000363410863"},{"@type":"NRID","@value":"9000237754756"},{"@type":"NRID","@value":"9000363407879"},{"@type":"NRID","@value":"9000363408454"},{"@type":"NRID","@value":"9000392819307"},{"@type":"NRID","@value":"9000363410995"},{"@type":"NRID","@value":"9000363409347"},{"@type":"NRID","@value":"9000392819407"},{"@type":"NRID","@value":"9000363487560"},{"@type":"NRID","@value":"9000363487344"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/sakanada"}],"foaf:name":[{"@value":"Sachie
