The well-known time series dataset based on a combination of contact measurements data and satellite altimetry was analyzed to investigate circumpolar spatiotemporal variability of the Southern Polar frontal zone’ width and the positions of the Subantarctic and Southern Polar fronts. The sequence analysis was used as the main method of the study. Sequences of (1) basic statistics of the fronts positions and (2) Spearman correlation coefficient values between neighboring timeseries of the frontal zone width and fronts position were analyzed. It was shown that variability of the Southern Polar frontal zone width is inhomogeneous in space, despite the close coordination of variability of the Subantarctic and Southern Polar fronts contours. On the scales of the Southern Polar frontal zone, three areas with different patterns of variability were detected: Atlantic, Indian and Pacific. The greatest variability (in respect to the average) of the Southern Polar frontal zone width was found in its narrow sections.
