While substances injected in the troposphere remain for a few weeks at most, emissions in the
stratosphere can linger for months or years.
If the "Wise Users" are right, this is a natural process: volcanoes, forest fires, and oceanic evaporation are constantly contributing chlorine to the
stratosphere in amounts that dwarf the total inventory of CFCs the entire human race has managed to produce.
Although volcanoes are capable of producing large quantities of hydrochloric acid, most plumes are not powerful enough to penetrate the
stratosphere.
The Montreal Protocol, signed in 1987 and effective from 1989, banned the use of ozone-depleting substances, and scientists reported seeing a recovery of the layer since the 1990s, mainly in the upper layers of the
stratosphere. In 2016, even the (http://www.ibtimes.com/antarctic-ozone-hole-showing-first-signs-healing-scientists-say-2388781) hole over Antarctica was declared to be healing .
Moreover, warming and ENSO signals in the upper
stratosphere and lower troposphere were studied.
Researchers focused their study on the
stratosphere's polar night jet stream, looking at 30 years of forecast data to analyze the connection of stratospheric conditions to forecasting accuracy.

Stratosphere located in the Makati Central Business District.
Water vapor is the most important greenhouse gas, and its impact on climate is amplified in the
stratosphere. In a detailed study, the researchers from the three institutions examined the causes of changes in the temperatures and water vapor in the tropical tropopause layer (TTL).
12 ( ANI ): NASA scientists have found that declining chlorine in the
stratosphere has not yet caused a recovery of the ozone hole - formed annually over Antarctica.
He also received a trophy the size of the
Stratosphere to show off back home.
Water vapour and ozone in the
stratosphere can have a large impact on earth's climate.
