Besides SSCE, scientists have also been investigating stratospheric sulfur injections — firing sun - reflecting aerosols into the air, similar to the cooling effect after a volcanic eruption — and cirrus cloud thinning, where you thin the top level of clouds, which have a warming effect on the planet.

The stratospheric sudden warming events analyzed in the paper are driven by air waves traveling upward from the troposphere — «so one could argue whether or not the troposphere is the primary cause of events,» Reichler says.

In the winter, intermixing of stratospheric ozone with the troposphere in a process called Stratospheric Tropospheric Exchange (STE) is the chief means of ozone transport into our air, but Dr. Wang says in summertime that process subsides and lightning bolts create significant ozone enhancements in the middle to upper troposphere, particularly in the Soustratospheric ozone with the troposphere in a process called Stratospheric Tropospheric Exchange (STE) is the chief means of ozone transport into our air, but Dr. Wang says in summertime that process subsides and lightning bolts create significant ozone enhancements in the middle to upper troposphere, particularly in the SouStratospheric Tropospheric Exchange (STE) is the chief means of ozone transport into our air, but Dr. Wang says in summertime that process subsides and lightning bolts create significant ozone enhancements in the middle to upper troposphere, particularly in the Southeastern US.

NASA and NOAA are mandated under the Clean Air Act to monitor ozone - depleting gases and stratospheric depletion of ozone.

Murphy's colorful blog, «Super-TIGER on the Ice,» documented the alternating moments of astonishing natural beauty (sparkling glaciers at 2 a.m., surprise penguin visits) and technical tedium (such as making sure the detector's connections still work in the thin stratospheric air).

(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.)

Because of this, and the lower density of air in the stratosphere, he says, «stratospheric emissions generally cause larger perturbations» and so cause more concern.

The Montreal Protocol had no impact on cleaning the air, it stopped the growth of CFCs which are powerful greenhouse gases (in addition to their role in depleting stratospheric ozone), therefore it slowed global warming, rather than increasing it, and we aren't trying to save ground - level ozone.

There can / will also be a shift in the tropopause (relative to mass — I am not referring to thermal expansion, though that happens; thermal contraction happens in layers that cool), which means that some layer of air is reclassified from stratospheric to tropospheric (for an upward shift).

Cold air at the top of ascending columns is forced to one side by warmer air continuing to flow up from beneath but it is blocked by the warmer stratospheric air above and so flows laterally and downward to the top of descending columns, following the undulating slope of the tropopause.

These include the influences of a changing climate, altered air mixing and transport rates, energy exchange, and changes in the composition of the atmosphere (e.g., water vapor, methane, nitrous oxide, aerosols, etc.), all of which can influence stratospheric ozone.

«In winter, the freezing Arctic air is normally «locked» by strong circumpolar winds several tens of kilometers high in the atmosphere, known as the stratospheric polar vortex, so that the cold air is confined near the pole,» said study co-author Marlene Kretschmer from the Potsdam Institute of Climate Impacts Research in Germany, in a press release.

Hypothetically (and the relationship is already well established statistically) the gamut of Mid Winter Warmings, Sudden Stratospheric Warmings and Final Warmings in the Arctic stratosphere depend upon the supply of ozone rich air from mid latitudes being thrust into the Arctic stratosphere where ozone is normally in a somewhat depleted state due to erosive nitrogen compounds descending from the mesosphere, in turn related to Particle Precipitation Events that are strongly related to geomagnetic influences and the solar wind.

Erl on Feb 18, 15:03:07 «Sudden stratospheric warmings in the Arctic depend upon the transport of ozone rich air from above the Sea of Japan.

Sudden stratospheric warmings in the Arctic depend upon the transport of ozone rich air from above the Sea of Japan.

In addition, a phenomenon called sudden stratospheric warming, apparently the result of strong downward air motion, also occurs in the late winter and spring at high latitudes.

The warm air intrusion followed two other related and noteworthy weather events, a sudden warming of the stratosphere, known as a sudden stratospheric warming event, and a splitting of the polar vortex.

(Any higher and they start to suffer stratospheric heating due to the vertical temperature profile reversing at the tropopause — the lapse rate changes sign and the air gets warmer instead of colder with altitude.)

It says nothing about real world events since then which, despite increasing ghgs, have gone into reverse with a cessation of stratospheric cooling and a return back equatorward of the air circulation systems.

The polar vortex, or stratospheric jet stream, is a large area of low pressure and cold air surrounding both of Earth's poles.
