Sentences with phrase «stratospheric ozone formation»

This paper develops a new theory of stratospheric ozone formation in situ at high latitudes, based upon tropospheric transport and conversion of paramagnetic oxygen.

Not exact matches

In September, the ozone hole is at its largest because the cold winter months coupled with the returning daylight permit stratospheric cloud formations that do the most damage to the ozone layer.

(Such low air temperatures encourage the formation of icy clouds in the upper atmosphere known as polar stratospheric clouds, which foster the chemical reactions that turn harmless chlorine compounds into ozone eradicators.)

Aircraft emissions probably play a crucial role in ozone destruction by fuelling the formation of polar stratospheric clouds.

This could enhance the formation of polar stratospheric clouds, which convert potential ozone - depleting species to their active forms.

In an idealized three - dimensional numerical simulation of the Northern Hemisphere winter stratosphere, doubling the CO2 concentration leads to the formation of an Arctic ozone hole comparable to that observed over Antarctica, with nearly 100 % local depletion of lower - stratospheric ozone.
