| Research Abstract |
Typhoon-ocean interactions were studied with an ocean general circulation model coupled with a carbon equilibrium model and a nonhydrostatic atmosphere model coupled with ocean wave model, a multilayer ocean model. Numerical simulations lead to clarify that sea-to-air CO_2 flux rapidly increases during the passage of a typhoon, resulting in ocean acidification, that drag coefficients reduce as surface winds increase under high winds, and that the impacts of variations in sea surface temperature with increases in chlorophyll a on typhoon intensity are smaller than those of preexisting oceanic conditions
