The effect of small-scale inhomogeneities on ozone depletion in the Arctic
Article Abstract:
A high-resolution model with simple ozone depletion chemistry reveals that ozone depletion in the Arctic is sensitive to small-scale inhomogeneities in the distribution of reactant species. The non-linearity of the governing law, included in the model accounts for this sensitivity to the small-scale inhomogeneities. The effect accounts for about 40% of the difference between predicted and observed ozone depletion in the Arctic during the 1994-1995 winter. The ozone loss within the vortex is predicted to range from 17% to 43% at the end of Mar 1996.

Estimates of ozone depletion and skin cancer incidence to examine the Vienna Convention achievements
Article Abstract:
A comparison of the no restriction and restrictive scenarios specified under the 1985 Vienna Convention for the estimation of ozone depletion and skin cancer incidence reveals the importance of the international measures. The no restriction and Montreal Protocol scenarios show an increase in the skin cancer incidence up to four and two times respectively by the year 2100. The Copenhagen Amendments scenario leads to an ozone minimum by the year 2000 and skin cancer incidence of about 10% by the year 2060.

Increased stratospheric ozone depletion due to mountain-induced atmospheric waves
Article Abstract:
Chemical reactions on polar stratospheric cloud (PSC) particles lead to the production of reactive chlorine species, which result in ozone destruction. Chlorine activation proceeds faster at low temperatures when cloud particle surface area and heterogeneous reaction rates are raised. Observations of mountain-wave-induced mesoscale PSCs with temperatures lower than expected are described. Such PSCs were found to lead to nearly complete conversion of inactive chlorine to ozone-destroying forms.
