Ozone
“Ozone Hole” “The word hole isn’t literal; no place is empty of ozone. Scientists use the word hole as a metaphor for the area in which ozone concentrations drop below the historical threshold of 220 Dobson Units.”

Eddy Heat Flux

Strong negative fluxes indicate poleward flux of heat via eddies. Multiple strong poleward episodes will result in a smaller polar vortex, Sudden Stratospheric Warmings and an earlier transition from winter to summer circulations. Relatively small flux amplitudes will result in a more stable polar vortex and will extend the winter circulation well into the Spring

  1. Readers are reminded that “changes” in the (southern) polar vortex (due to climate change) are regularly blamed for the many years of steadily increasing Antarctic sea ice extents and sea ice area surrounding Antarctica. Supposedly, the increased winds blow the sea ice away from the shoreline, opening up new ocean water to the fresh water-diluted Antarctic Ocean surrounding the continent (the increased fresh water volume being due to the increased melting of the Antarctic land ice), and thus allowing sea ice to freeze. Winds increase again, get blow away from the continent, more sea ice freezes.

    The concept does not make sense thermodynamically, nor physically – since the air temperature above Antarctica has been decreasing, the polar vortex winds have not been increasing, and the mass of land ice above the continental land mass has been increasing everywhere except the 4% of land in the West Antarctic Peninsula. (Which is the only area on the continent that is warming.) Further, the small bit of “fresh water” that does melt under glacier ice on the continental edge immediately re-freezes as long runnels of ice underwater as soon as it hits the below-freezing (very salty) ocean water around the coasts. It cannot dilute the tens-of-thousands-times larger Antarctic Ocean surrounding the continent.

    This reference page will be a very useful source.
