- Heat and Mass Transfers in Urban Atmosphere
Accurate estimates of CO2 exchange flux across the air-sea interface are very important for predicting the climate change due to global warming. Advanced laboratory and field studies are carried out to develop atmosphere-ocean-wave coupled models describing air-sea momentum and CO2 transfers. Also, direct numerical simulation (DNS) is made to reveal the physical mechanism of gas transfer at the water surface from viewpoints of turbulence dynamics.
