Even the distribution of total column ozone is known to reflect transport processes. Therefore, GOME total column ozone data can be used to study dynamic processes on different scales as it is demonstrated in the diagram. The data also reveal that the northern polar vortex was well established during that period. Beyond these synoptical features, the data clearly show a variety of medium and even small scale structures. They are highly variable on time scales of one day or so and are believed to play a substantial role in the understanding of the stability of vortices and especially of their delicate boundary areas.
Streamers are therefore the objective of intense studies.
