The most recent models dealing with CO2 uptake by the ocean divide the ocean by latitude, but they do not take into account the influence of the different wind regimes on the CO2 fluxes across the air-water interface. However, new gas exchange experiments run in wind tunnels have shown a great enhancement of the transfer velocity at high wind speeds as a result of the development of breaking waves. A study of sensitivity of two different models (Siegenthaler outcrop box diffusion model and Takahashi-Azevedo inclined box diffusion model) to an increase of the CO2 transfer velocity at high latitudes (outcrop regions of the deep ocean) is undertaken. It is shown that the variations in the transfer velocity with latitude must be taken into account.
