The presence of a thinned area or craterlike feature in the Arctic polar ozone layer during March, 1986 has been reported previously (Can. J. Phys. 67, 161 (1989)). In this paper the morphology of the reappearance of the crater from January to March, 1989 is described. It appeared over northern Europe in late January and moved over western Canada in late February. The minimum value of ozone in the crater floor had fallen from 300 DU (1 Dobson unit (DU) = 0.01 mm) in 1979 to a new low of less than 200 DU in 1989, which is similar to the thinned total ozone columns observed within the Antarctic ozone hole. Analysis of the available total ozone mapping spectrometer ozone measurements indicates that the crater could be explained by a combination of two mechanisms; a chemical process, which depleted the ozone concentrations at altitudes in the 14–22 km region, and a transport process, which shifted the altitude distribution of ozone upwards such as a vertical circulation cell. Although the Arctic ozone crater is similar in several aspects to the Antarctic ozone hole, there remain several differences; the issue is whether the crater and the hole are manifestations of the same phenomenon. We consider that the Arctic ozone crater is mainly produced by dynamic redistribution driven by tropospheric circulation features.
