Abstract
The falling of a large celestial body into the ocean causes a large number of compounds (for example, HCl, Cl, Br, Na, H2O, OH, and NO) that destroy ozone molecules directly or indirectly to be ejected to stratospheric altitudes. The bleaching of the atmosphere in the UV range as a result of such ozone destruction creates negative feedback that restores the ozone. The characteristic time for such restoration in the stratosphere decreases sharply with altitude, ranging from several months at 30 km to several days at 20 km.
