Regional-Scale Ozone Deposition to North-East Atlantic Waters

Figure 1

Comparison of deposition velocity as a function of reactivity for the nonturbulent and the turbulent Fairall et al. [13] scheme for differing 10 m wind-speeds (U10). Nonturbulent deposition velocity is obtained by solution of the basic ozone conservation equation, whereas the turbulent deposition velocity is obtained by solution of the conservation equation including a turbulent eddy diffusivity term that is obtained from surface-layer similarity scaling [27]. Note how both schemes converge for high reactivity values. This occurs because in incidences of very high oceanic reactivity, ozone is destroyed so rapidly in the ocean surface layer that ocean turbulence has no enhancing effect on deposition velocity.
