For animation, a
very important video on the destruction of the ozone layer produced by the
ECMWF (European Center for Medium-Range Weather Forecasts) was selected. It
shows that the decrease in concentrations of the ozone layer in the
stratosphere has the consequence of the formation of the ozone hole over the
Antarctic continent. Each year the hole expands due to the presence of
undesirable gases and the complex meteorological processes and photochemical
reactions that occur continuously in the stratosphere.
