The structure of the arctic winter stratosphere over a 10‐yr period
Abstract A series of 100‐mb temperature maps was drawn up for the winters 1949‐1950 to 1958‐1959 using 10‐day mean data. 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, both highly per...
