Where does the ozone hole occur?
The ozone hole occurs during the Antarctic spring, from September to early December, as strong westerly winds start to circulate around the continent and create an atmospheric container. Within this polar vortex, over 50 percent of the lower stratospheric ozone is destroyed during the Antarctic spring.Click to see full answer. In this way, where is…

Antarctica Subsequently, question is, is there still a hole in the ozone layer 2019? 2019 Ozone Hole is the Smallest on Record Since Its Discovery. Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since 1982, NASA and NOAA scientists reported today. Moreover, what caused the ozone hole? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity.When did the ozone hole form?The Antarctic ozone hole is an annual phenomenon which has occurred in every (southern hemisphere) spring since the late 1970s. It is caused by the chemical action of chlorine and bromine released from man-made chlorofluorocarbons (CFCs) and halons.
