– This phenomenon is driven by chemical reactions involving ozone-depleting substances (like CFCs) which are catalyzed on the surface of polar stratospheric clouds (PSCs) that form at very low temperatures in the polar stratosphere during winter.
– The depletion becomes pronounced in spring when sunlight returns, initiating the catalytic cycles.
– Mid-latitude depletion is less severe than polar depletion.
– Equatorial and tropical regions experience relatively less ozone depletion due to different stratospheric temperature and circulation patterns.
