AB: The high spatial resolution observations of OMI and Sciamachy of the ozone column amount distribution provide detailed information on structures in the ozone layer. In the subtropics coherent bands of low ozone were present during a couple of days in august $2004$ in the southern hemisphere. On the basis of these observations and analysis of the potential vorticity distribution, an interpretation in terms of propagating planetary waves is put forward. This interpretation and the analysis will be enlightened. The consequences of the planetary waves on the distribution of ozone in the tropics and subtropics will be discussed.
