Restored ozone halts wandering jet stream

The healing ozone layer above Antarctica is shifting wind patterns around the globe — most notably, pausing the movement toward the pole of the summertime jet stream in the Southern Hemisphere. Satellite observations and climate simulations reveal that the jet stream shifted from about 49° S to 51° S between 1980 and 2000. After 2000, when the ozone layer began to recover as a result of the Montreal Protocol that effectively banned ozone-killing chemicals, the change has halted.
