Rare And Unusually Large Ozone Hole Over Arctic and Northern Canada

[Elderberry]

By Strange Sounds -Mar 19, 2020

The formation of a large ozone hole is extremely rare over the Arctic regions during the late winter/early spring season.

But again, this year is beating records of unusual weather anomalies… And we get an unusually large area of ozone depletion.

This year, the ozone has started depleting in January 2020, when a mini ozone hole formed over northern Europe.

Such ozone holes over the North Pole aren’t triggered by aerosols and their chemical destruction processes like over Antarctica, but just dispersed by specific weather circulation patterns.

These events are mostly short-lived and tend to occur every year during the cold season.

There is currently a giant hole forming over the Arctic, and this time it is linked to an ozone destruction process.

It isn't related to lower solar activity (lower solar winds) interacting with the atmosphere?

Not according to the article:

Since sunlight is limited during Arctic winter, ozone depletion is very rare. And when sunlight reaches the pole in late February and March, the stratosphere isn’t cold enough to produce these stratospheric clouds.

But this year, the stratosphere over the North Pole is abnormally cold. Stratospheric clouds can form while sunlight reaches the pole, triggering ozone destruction, as shown in the diagram below.

But hey in 1987 a boatload of countries signed on to the Montreal Protocol which took effect in 1989 which called for the phasing out of CFC's and Halons which we were told were responsible for the Ozone hole and here we are decades later (of course we can all be assured that China and some others routinely violated the treaty) and low and behold we still have Ozone holes of fluctuating sizes even though we are constantly pushed into using less efficient or more expensive refrigerants.

"Hole in the Ozone"?  Big deal? It was explained to me many yrs ago that the increased UV people were exposed to due to the hole was the same as people experience by moving 50 miles closer to the equator.

Sorry, that was me.

It’s because of that damn groundhog ending winter early
