Abstract : A series of 100-mb temperature maps were drawn for the winter 1949-50 to 1958-59 using ten-day mean date. These maps were used to summarize the large-scale events of each winter and of the ten winters in general. The results suggest the existence of two major patterns: an asymmetric pattern with a warm ridge over east SiberiaAlaska and an elliptical cold-core vortex over Eurasia; and an eccentric bi-polar distribution, the trough line extending from central Canada to central Siberia. The striking asymmetry of both patterns in the stable stratosphere appears to require an external forcing agent and this analysis tends to highlight the role of tropospheric activity. (Author)
