19 December 2016

We would normally associate jet streams with the weather but, thanks to ESA’s magnetic field mission, scientists have discovered a jet stream deep below Earth’s surface – and it’s speeding up.

Launched in 2013, the trio of Swarm satellites are measuring and untangling the different magnetic fields that stem from Earth’s core, mantle, crust, oceans, ionosphere and magnetosphere.

Together, these signals form the magnetic field that protects us from cosmic radiation and charged particles that stream towards Earth in solar winds.

Measuring the magnetic field is one of the few ways we can look deep inside our planet. As Chris Finlay from the Technical University of Denmark noted, “We know more about the Sun than Earth’s core because the Sun is not hidden from us by 3000 km of rock.”

The field exists because of an ocean of superheated, swirling liquid iron that makes up the outer core. Like a spinning conductor in a bicycle dynamo, this moving iron creates electrical currents, which in turn generate our continuously changing magnetic field.

Tracking changes in the magnetic field can, therefore, tell researchers how the iron in the core moves.

The accurate measurements by the unique constellation of Swarm satellites allow the different sources of magnetism to be separated, making the contribution from the core much clearer.

 A paper published today in Nature Geoscience describes how Swarm’s measurements have led to the discovery of a jet stream in the core.

Phil Livermore from the University of Leeds in the UK and lead author of the paper said, “Thanks to the mission we have gained new insights into the dynamics of Earth’s core and it’s the first time this jet stream has been seen, and not only that – we also understand why it’s there.”

One feature is a pattern of ‘flux patches’ in the northern hemisphere, mostly under Alaska and Siberia.

“These high-latitude flux patches are like bright spots in the magnetic field and they make it easy to see changes in the field,” explained Dr Livermore.

Swarm reveals that these changes are actually a jet stream moving at more than 40 km a year – three times faster than typical outer-core speeds and hundreds of thousands of times faster than Earth’s tectonic plates move.

“We can explain it as acceleration in a band of core fluid circling the pole, like the jet stream in the atmosphere,” said Dr Livermore.

So, what is causing the jet stream and why is it speeding up so quickly?

The jet flows along a boundary between two different regions in the core. When material in the liquid core moves towards this boundary from both sides, the converging liquid is squeezed out sideways, forming the jet.

“Of course, you need a force to move the fluid towards the boundary,” says Prof. Rainer Hollerbach, also from the University of Leeds.

“This could be provided by buoyancy, or perhaps more likely from changes in the magnetic field within the core.”

As for what happens next, the Swarm team is watching and waiting.

Rune Floberghagen, ESA’s Swarm mission manager, added, “Further surprises are likely. The magnetic field is forever changing, and this could even make the jet stream switch direction.

“This feature is one of the first deep-Earth discoveries made possible by Swarm. With the unprecedented resolution now possible, it’s a very exciting time – we simply don’t know what we’ll discover next about our planet.”

2017-03-06 - Oceans reaching limits of heat-absorption resulting in major surge in atmospheric warming:

Quote: "The oceans have been absorbing the lion's share of global warming in recent years, sparing land dwellers the worst of the heat. That's about to change."

2017-04-04 - The Gulf Stream is heating up as the 2017 El Niño strengthens:
http://robinwestenra.blogspot.com/2017/04/abrupt-climate-change-04042017.html

Note: Where's all that hot water gonna go? Up around the East Coast, where that huge and already-melting methane clathrate deposit is located. Europe is downwind of that deposit. That doesn't mean the wind won't shift from time to time and destroy the East Coast some too though, once that deposit really starts blowing its wad. There's enough methane in that one deposit to cause 250,000 ten-kiloton Hiroshima-sized explosions...

2017-04-04 - So far, 2017 is in the running to be the 4th consecutive hottest year on record:

2017-04-11 - Global warming could thaw far more permafrost than expected:

http://www.newsweek.com/climate-change-permafrost-methane-global-warming-581596
http://www.nature.com/articles/nclimate3262.epdf

Quote: "There is already significant evidence that the tundra is starting to break up with a massive crater known as the Gateway to the Underworld growing in Siberia at an alarming rate."

Quote: "But scientists do agree that Arctic permafrost has a formidable potential to affect the climate. Estimates suggest that the amount of carbon it contains may be up twice the amount of carbon currently housed in the atmosphere."

Note: So there's the equivalent of almost 800 ppm of carbon dioxide locked up in the permafrost, which has already started to significantly melt away. If that were added to the 400 ppm we already have in the atmosphere, that'd be 1200 ppm, or 200 ppm more than what scientists have estimated was present in the atmosphere for the Permian-Triassic extinction event, called The Great Dying. So this is another sign that a repeat of the Permian-Triassic extinction is underway now. This may be how it began back then too - volcanic eruptions burned a bunch of coal (instead of humans, but the source is irrelevant to the Earth), the CO2 levels hit 400-ish ppm, the Earth heated up and melted the permafrost which kicked the levels up to 1000+ ppm, and the oceans and seas went anoxic enough to spew enough hydrogen sulfide into the seas and the atmosphere to kill off 96% of all ocean species and 70% of all land species. So yeah, that's what's coming our way, and it has already begun.

And the permafrost isn't even the only source of greenhouse gases. There are numerous oceanic methane clathrate deposits that are ALSO now melting, off both the US East and West Coasts, off the coast of New Zealand, in the sea near Svalbard, etc, so we may see WORSE than 'The Great Dying'. Well, WE won't see it, because we'll all be long gone way before it gets that bad. But the EARTH may see worse than 'The Great Dying', and it took 30 million years to fully recover from that, so it may take 35 or 40 million years for the Earth to fully recover after the current extinction event has run its course...

2017-07-19 - Indicators of geothermal heat under the Greenland glacier:
http://robinwestenra.blogspot.com/2017/07/geothermal-heat-under-greenland-glacier.html

Quote: "Steamers rising from the Greenland glacier could be a sign of geothermal heat under the glacier. If so, it is much about ideas and theories about the Earth's crust in Greenland, according to volcanologists. 'Men have not noticed this until now. There's something going on there. We just do not know what it is,' says Haraldur Sigurðsson, volcanologist, who discusses the steam bulbs on his website."

Note: Uh huh, that's heat rising from BELOW. There's nothing we can do about that...

Geotectonic Ocean Heat Transfer Theory-Ice Free Arctic 2018
« Reply #144 on: March 23, 2018, 04:14:19 AM »
http://arctic-news.blogspot.com/2018/

The Arctic is warming up more than twice as fast as the rest of the world, due to numerous feedbacks. At times, large areas over the Arctic Ocean can become 30°C or 54°F warmer than 1979-2000, as illustrated by the image below.
