The winter warmth after the Pinatubo emption was concentrated over Scandinavia and Siberia and central North America. These temperature anomalies were associated with marked departures in sea-level pressure patterns in the first northern winter. There was a pole-ward shift and strengthening of North Atlantic westerlies at —60° N, associated with corresponding shifts in the positions and strengths of the Iceland Low and Azores High. These effects have been modeled as a result of changes to the atmospheric circulation around the Arctic (the Arctic Oscillation Thompson and Wallace (1998)) arising from the differential heating effects of the volcanic aerosol... 

Using a photochemical box model of the MBL, Sander and Crutzen (1996) showed that the reaction cycles that were proposed for the cycling of halogens on and within aerosols under conditions for the Arctic can also occur under polluted conditions at mid-latitudes. Vogt et al. (1996) proposed an autocatalytic mechanism for the release of bromine under clean conditions. They showed that Br2 and BrCl can degas s from the particles, photolyze in the gas phase, and destroy O3 in an autocatalytic cycle. HOBr, which is... 

The data given by Murozumi et al. (38) for salt and dust in Arctic and Antarctic snows and ice are of interest. The salt-to-dust ratios in those samples range from 2.5 to 100 and are reasonably within the extremes shown in Table I for atmospheric aerosols. In their samples, the Na/K do not exceed 22 (seawater ratio is 28) and are lowest when the salt-to-dust ratios are low (39, 40). The second point is compatible with a salt and dust mixing model 12), and the first demonstrates the ratios found in a fractionated marine aerosol (40). 

For heterogenous chemistry in the Arctic tropospheric boundary layer, the HBr acid ionization study summarized here in Sec. 4 is only the very first step. The key reactions Eqn 3 on ice remain to be examined, a topic of current study. One general and salutary lesson of the HBr acid ionization reviewed in Sec. 4 — and one that applies to all modelling of heterogeneous chemistry on atmospheric aerosols — is that the results of very small cluster studies are not necessarily relevant for the atmospheric situation.
