Abstract
From a GCM simulation of a period in EASOE, the evolution of the north ern hemisphere polar vortex is examined by means of a sequence of thre e dimensional visualizations. Use is made of two key dynamical feature s, the edge of the polar vortex and the height of the tropopause. This technique clearly shows bow the vortex is disturbed by an anticycloni c tropospheric anomaly and how this disturbance vertically propagates up the vortex. An objective method for finding the edge of the vortex is presented.
