Horizontal movements in the ozone layer

Abstract

The variations of the column ozone densities at Middle-Asian stations and several others in the former USSR were examined by auto- and cross-correlation analyses. Periodic processes with amplitude of tens of DU and periods of 15 to 25 days occur simultaneously at many stations. The movement of this wave disturbance is directed towards the south-east and can also be seen in the weather maps at 500 hPa and 100 hPa, and the driving force is most probably meteorological air motion.
