DEF

Hypothèse selon laquelle la quantité d'ozone détruit photochimiquement dans la stratosphère engendre, à cause d'une plus grande disponibilité de l'oxygène atomique et diatomique, la production d'une quantité à peu près égale de molécules d'ozone.

OBS

Cette hypothèse ne peut expliquer les importantes variations saisonnières d'ozone et elle ne se vérifier pas au-dessous de trente-cinq kilomètres d'altitude.
