Here you can see the temporal development of the area with
|
|
j@1040
|
5 |
temperatures below a typical threshold temperature that is needed for
|
|
j@1040
|
6 |
for chlorine-catalyzing polar ozone depletion. The mean value of the
|
|
j@1040
|
7 |
volume of these low temperatures is a measure of the Ozone depletion.

The upper panel shows the temporal development of the area with temperatures
|
|
j@1040
|

below this temperature threshold. The lower panel shows the corresponding
|
|
j@1040
|
11 |
volume (solid line) and the mean value between mid-December and
|
|
j@1040
|
12 |
End of March (dotted line and right arrow).

For comparison, the corresponding mean values of other years are shown as coloured

arrows displayed at the right edge of the plot. In 2011 this quantity was
|
|
j@1040
|

about :math:`38 \cdot 10^6` km :math:`^3`.
