November 2008
This mini ozone hole can be traced back to a meteorological disturbance causing an ozone low forming off the East Coast of Canada around the 11th November; it was then advected over the Atlantic and became quasi-stationary over the UK intensifying somewhat on the 14th and 15th. This mini-hole covered most of the UK mainland (see Figure A). It then weakened and drifted into mainland Europe.
Figure A: Ozone anomaly for the 14th November which was the day of maximal extent.
