To determine the boundary region of the polar vortex objectively using the PV distribution on isentropic surfaces, the equivalent latitude(Eql) of the polar vortex boundary was calculated using a slightly modified form of the technique of E.R. Nash et al.(J. Geophys. Res., 101D, 9471, 1996). Using the NCEP/NCAR reanal- ysis data, the Eql of the polar vortex boundary region in the winter of 1999/2000 was calculated, and compared with the ozone mixing ratio in the lower stratosphere over Eureka observatory(80°N , 86°W ). The results indicate that this method determines the boundary region of the polar vortex well.
