Ozone gas is continuously formed by the action of UV rays on molecular oxygen, and also degraded into molecular oxygen in stratosphere. There should be a balance between production and degradation of ozone in stratosphere.
Of late, the balance has been disrupted due to enhancement of ozone degradation of chlorofluorocarbons(CFCs). CFCs are formed by anthropogenic activities like use of refrigerators, pesticides, artificial solvents, foam products.
UV rays react with CFCs releasing Cl atoms. These Cl atoms degrades ozone.
It is only under certain meteorological conditions that ozone hole is formed. The conditions are
Cold temperatures during polar winterIce cloud formationSpecial meteorological conditions to form the polar vortex.Followed by the polar sun rise in spring.
