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.
