Sentences with phrase «ozone depletion above»

«These extra particles may enhance the heterogeneous reactions, leading to ozone destruction, and this ozone depletion above Antarctica may worsen in 1992 by spreading to altitudes beyond the 12 to 20 kilometres layer.»

In contrast to this, strong ozone depletion above the Arctic was observed in a few cold winters only.

Not exact matches

The ozone hole is a severe depletion of the ozone layer above Antarctica that was first detected in the 1980s.

«This year, our balloon - borne instruments measured nearly 100 percent ozone depletion in the layer above South Pole Station, Antarctica, that was 14 to 19 kilometers (9 to 12 miles) above Earth's surface,» said Bryan Johnson, a researcher at NOAA's Earth System Research Laboratory in Boulder, Colorado.

The temperature of the stratosphere is one of the key factors in the springtime depletion of ozone above the Antarctic where in winter it gets colder than anywhere else on Earth, encouraging icy particles to form in polar stratospheric clouds.

Chlorine monoxide, which is produced by a similar series of reactions involving icy particles in the stratosphere, is blamed for the springtime depletion of ozone above Antarctica.

And ozone loss above the Antarctic, where numbing cold creates high - altitude clouds that speed ozone depletion, remains an intractable challenge.

By 2040 there is not only an ozone hole above the Antarctic for the entire year, but severe ozone depletion at much lower, more populous latitudes.

«This year, our balloon - borne instruments measured nearly 100 percent ozone depletion in the layer above South Pole Station, Antarctica, that was 14 to 19 kilometers (9 to 12 miles) above Earth's surface,» Bryan Johnson, a researcher at NOAA's Earth System Research Laboratory in Boulder, Colorado, said, in the statement.

The team attributes the change to patterns of higher winds, traceable to ozone depletion high above Antarctica, and to global warming.

Less intense depletion of ozone occurs above the Arctic and in mid-latitudes of both hemispheres.

I think her data implies that a more active sun producing more solar protons, in causing more depletion of ozone above 45Km, cools the mesosphere thereby enhancing the upward energy flux from stratosphere to mesosphere thus cooling the stratosphere too.

The Shindell and Schmidt abstract above says: «It has been suggested that both Antarctic ozone depletion and greenhouse gases have contributed to these trends.»

Satellites and weather balloon measurements show that the stratosphere, the layer from 10 to 50 kilometres above the Earth, is indeed cooling (although this is partly due to the depletion of the ozone layer).
