… The climatological structure, and interannual variability, of the Arctic and Antarctic
stratospheric polar vortices are examined by analysis of elliptical diagnostics applied to
over 19 yr of potential vorticity data. The … In this study, we calculate the EDs of both the
Arctic and Antarctic vortices using PV on isentropic surfaces from over 19 yr of
meteorological analyses (October 1978 to April 1998). These diagnostics are then used to
examine the climatological structure and interannual variability of both vortices. …
