DEF

Disparition inexpliquée d'une grande quantité d'ozone qui survient chaque année en octobre, durant le printemps austral, au-dessus de l'Antarctique.

OBS

En 1986, on a observé la disparition de quarante pour cent de l'ozone total. Il semble que le même phénomène de diminution printanière ait été observé en 1987, au-dessus de l'Arctique cette fois.
