Tracking Magnetic North: The Pesky Wildcard of the Eddy Minimum

#1 Post by anomalous howard » Mon Nov 12, 2018 7:12 pm

A GSM of a different color:
See the horizontal blue band tracking above 10...it's at just about 12. That's a scale of degrees on the left.
This is a track of the Magnetic North Pole's position relative to a tracking station in London.

About a year ago it was solidly on 10 degrees. (You can just make out the rising slope of the band during the one month of readings below) It's moved 2 degrees in the last year as seen by the difference between the above and below charts. If I recall correctly, one degree is about 74 kms as triangulated from the measuring station.

I've been wondering if the earth's pole shift combined with the solar pole movement is a contributing factor in the earth facing quiet. Something to do with magnetic cancellation. Any thoughts?

I think there are too many unknown variables to even begin ascribing cause and effect in that particular aspect of solar system dynamics.
The "Earth-facing quiet" that has been noted by some observers seems to be more than just a statistical anomaly though.

The Earth's magnetic pole movement AND the "Earth-facing quiet" may both be a result of a 3rd, as yet unidentified, influence or combination of influences.

It would be good to know when, exactly(ish), the "Earth-facing quiet" phase began with more detail on how it has progressed.
At the moment I would hazard to say that both sides of the Sun are now damn quiet.
The magnetic polar excursion started many decades ago but maybe there's a critical juncture in its progress that is related to a phase of sunspot "Earth-facing quiet".
Not enough data.

Bringing this post over here:
viewtopic.php?p=1932#p1932

And additionally:
A recent "explanation" for the pole shift. I'm not ready to buy into it at this point. There's no mention of the concurrent movement of the South Magnetic Pole and treats the North's movement as an isolated event.
09 JANUARY 2019
https://www.nature.com/articles/d41586-019-00007-1

"The release of the World Magnetic Model has been postponed to 30 January due to the ongoing US government shutdown."

"Something strange is going on at the top of the world. Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core. The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

On 15 January, they are set to update the World Magnetic Model, which describes the planet’s magnetic field and underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones.

The most recent version of the model came out in 2015 and was supposed to last until 2020 — but the magnetic field is changing so rapidly that researchers have to fix the model now. “The error is increasing all the time,” says Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information.

The problem lies partly with the moving pole and partly with other shifts deep within the planet. Liquid churning in Earth’s core generates most of the magnetic field, which varies over time as the deep flows change. In 2016, for instance, part of the magnetic field temporarily accelerated deep under northern South America and the eastern Pacific Ocean. Satellites such as the European Space Agency’s Swarm mission tracked the shift.

By early 2018, the World Magnetic Model was in trouble. Researchers from NOAA and the British Geological Survey in Edinburgh had been doing their annual check of how well the model was capturing all the variations in Earth’s magnetic field. They realized that it was so inaccurate that it was about to exceed the acceptable limit for navigational errors.

Wandering pole...
“That was an interesting situation we found ourselves in,” says Chulliat. “What’s happening?” The answer is twofold, he reported last month at a meeting of the American Geophysical Union in Washington DC.

First, that 2016 geomagnetic pulse beneath South America came at the worst possible time, just after the 2015 update to the World Magnetic Model. This meant that the magnetic field had lurched just after the latest update, in ways that planners had not anticipated.

Second, the motion of the north magnetic pole made the problem worse. The pole wanders in unpredictable ways that have fascinated explorers and scientists since James Clark Ross first measured it in 1831 in the Canadian Arctic. In the mid-1990s it picked up speed, from around 15 kilometres per year to around 55 kilometres per year. By 2001, it had entered the Arctic Ocean — where, in 2007, a team including Chulliat landed an aeroplane on the sea ice in an attempt to locate the pole.

In 2018, the pole crossed the International Date Line into the Eastern Hemisphere. It is currently making a beeline for Siberia.

The geometry of Earth’s magnetic field magnifies the model’s errors in places where the field is changing quickly, such as the North Pole. “The fact that the pole is going fast makes this region more prone to large errors,” says Chulliat.

To fix the World Magnetic Model, he and his colleagues fed it three years of recent data, which included the 2016 geomagnetic pulse. The new version should remain accurate, he says, until the next regularly scheduled update in 2020.

Core questionsIn the meantime, scientists are working to understand why the magnetic field is changing so dramatically. Geomagnetic pulses, like the one that happened in 2016, might be traced back to ‘hydromagnetic’ waves arising from deep in the core 1. And the fast motion of the north magnetic pole could be linked to a high-speed jet of liquid iron beneath Canada 2.

The jet seems to be smearing out and weakening the magnetic field beneath Canada, Phil Livermore, a geomagnetist at the University of Leeds, UK, said at the American Geophysical Union meeting. And that means that Canada is essentially losing a magnetic tug-of-war with Siberia.

“The location of the north magnetic pole appears to be governed by two large-scale patches of magnetic field, one beneath Canada and one beneath Siberia,” Livermore says. “The Siberian patch is winning the competition.”

Which means that the world’s geomagnetists will have a lot to keep them busy for the foreseeable future."

And then...again...my own map showing the North Magnetic Pole to be already where it was projected to in 2020. Across the International Date line (Prime Meridion)

Suspicious 0bserver commentary on the article about the 2016 acceleration of the North Magnetic Pole shift:
