Well, this is, how you say, Very Interesting….
Sun takes a nap, UV falls off a cliff, a bunch of other ‘odd things’ happens, and now the Ozone Hole has abandoned Antarctica and headed to the Arctic…
Here is a live map (that will initially be the same) for comparison to the static map in the posting below:
For some time now I’ve been watching the Ozone Deviation Map from this site:
For posterity, I’m saving a static image of that map here:
In a posting some time back, I’d noted that it looked like the North Pole was ‘thinning’ a bit:
There are a couple of areas of low ozone at the North Pole, but strong variations on the south. That’s what I used to see on the opposite pole before. Here is a quasi-representative map selected from 1998 (but with a really strong “ozone hole” over the south pole):
OK, so in this “anomaly” map, we’re not seeing much wrong at the North Pole, but the South Pole as “two red eyes” of higher than normal ozone. That is a feature I’d noted more commonly on the North Pole (and I speculate is the ‘landing zone’ of a Birkeland Current, so you get the twin current creating two places with added ozone from electrical discharge). More typical of the South Pole “Ozone Hole” is this next anomaly map showing the strongly depleted “Ozone Hole” over the South Pole and two “yellow eyes” over the North. That has been “typical” for a while.
So, OK, what does this mean? Nothing? Who knows what? That the Birkland Current has swapped polarity? That we’re going to get an Ozone Hole at the North Pole? That I ‘randomly’ sampled on a too small biased basis as I was just browsing? That a day by day look is prone to wild meaningless swings and we need annual average maps?
Well, looks like we are getting our answer to that question from the last posting. The Ozone Hole is swapping poles. Now just wait for all the hand wringing about the “added” or “new” ozone hole (and complete silence about the other end of the planet, or how one can get bigger and the other smaller both caused by people and a well distributed gas… at about the equinox and on an “anomaly” basis…)
Some other images from that earlier posting are reproduced here as well. These are total ozone, not just the anomaly:
Update 7 March 2011
Just adding a couple of maps for further data points. First up is an average of Ozone (not the deviation, actual ozone levels) for February 2011. Notice that Ozone level is quite high, up where it’s supposed to be dark in winter… so if UV isn’t making that Ozone, what is?
Solar UV output is ‘way down’ and we see fairly low ozone levels around the entire equator (where one would expect solar UV to be quite high) but with ‘hot spots’ over the North high latitude areas that have quite high levels. From day to day and month to month the location of those “ozone eyes” changes, but they tend to be a persistent effect.
Here is “March 1998 Average” actual ozone so you can see what the typical pattern has been:
Notice the two “bright red eyes” at the North Pole? This is the month of the Equinox, so day length is roughly equal everywhere on the planet. Solar angle will change, so the poles will both be getting low angle light.
And for comparison, here is the current “live map” of “all ozone”:
And the April “normal” historical. To me it looks like excess ozone at the North Pole and more or less constant ozone over the rest of the planet with a 250-300 ish range:
It looks to me like whatever was making the “excess ozone” at the North Pole has throttled back and it’s drifting down to match the South Pole; which is similarly losing it’s “ozone hole” anomaly.
And this is explained by well mixed gasses how?
Update 4 April 2011
OK, here is a custom made map showing the March 2011 “anomaly” (which they call “deviation” – and is more accurate a term, btw) and the March 2011 Total Ozone. Also, just as a “things that make you go Hmmmm” I’ve added the ozone chart for 11 March 2011 when the Japan 9.0 quake happened. Notice that if the “Bright Red Eye” is made by the landing of a Birkeland Current flow, it was landing near Japan…
As you can see, there is a very broad North Pole “deviation” or “anomaly” to the negative side over the entire month of March.
Here we see a weaker than usual form of the “red eyes” higher ozone levels that I speculate is the landing zone of a Birkeland Current. And what about on the day of the 9.0 Quake in Japan?
Things that make you go “Hmmmm”… A Bright Orange Spot right near Japan… And the day before the quake? Even brighter spot… but further away and aproaching Japan…
Does it mean anything? I have no idea… Hmmmm…. But when all those aftershocks were happening?
That is one mighty strange “coincidence”… Hmmmm… mmm…mmmm…
