The year with weak wave energy (top) clearly shows
greater ozone loss, which extends over a wider area, reaching farther past the edge of Antarctica and closer to the tip of South America.
Colder temperatures and weaker high - altitude winds may make the arctic polar vortex even more intense in future winters and trigger
greater ozone loss, says atmospheric scientist Paul Newman of NASA's Goddard Space Flight Center in Greenbelt, Maryland, although the losses probably won't approach those in Antarctica.

Data from observations in Japan itself show that the
greatest loss of
ozone — 4.5 per cent over the past 10 years — occurred over the city of Sapporo, which lies on the same latitude as Marseilles.
All that is said referring to the figure is «[Rex and his colleagues report that] after this winter's unusually low Arctic temperatures,
ozone losses are
greater than any seen before (see graph).»
Alternatively, a milder winter, provided it was still cold enough to lead to chemical processing of halogens, could be followed by
greater springtime
ozone losses if temperatures stayed cold longer.

ozone over the Arctic, which leads to
greater heat
loss.
