A three‐dimensional chemical‐transport model of the stratosphere has been used to study the 1996 austral winter and spring. Both the model and ozonesonde measurements show that ozone depletion associated with the Antarctic ozone hole follows the edge of polar night: very little ozone‐depleted air mixes ahead of the terminator as it sweeps poleward, until the terminator reaches 80°S. Other details of the model ozone field show very good agreement with measurements.
