{Simulated] Geomagnetic jerks finally reproduced and explained
Phys.org ^ | April 22, 2019

Posted on 04/22/2019 1:23:36 PM PDT by BenLurkin

The Earth's magnetic field experiences unpredictable, rapid, and intense anomalies that are known as geomagnetic jerks.

Initially described in 1978, geomagnetic jerks are unpredictable events that abruptly accelerate the evolution of the Earth's magnetic field, and skew predictions of its behaviour on a multi-year scale.

The Earth's magnetic field is produced by the circulation of matter within its metallic core, via the energy released when this core cools. Researchers know of two types of movements that cause two types of variations in the magnetic field: those resulting from slow convection movement, which can be measured on the scale of a century, and those resulting from "rapid" hydromagnetic waves, which can be detected on the scale of a few years. They suspected that the latter played a role in the jerks, but the interaction of these waves with slow convection, along with their mechanism of propagation and amplification, had yet to be revealed.

Julien Aubert from l'Institut de physique du globe de Paris (CNRS/IPGP/IGN/Université de Paris) developed, with a colleague from the Technical University of Denmark (DTU), a computer simulation very close to the physical conditions of the Earth's core. The simulation required the equivalent of 4 million hours of calculation, and was carried out thanks to the supercomputers of GENCI.

Researchers were subsequently able to reproduce the succession of events leading to geomagnetic jerks, which arise in the simulation from hydromagnetic waves emitted in the inner core.

Geomagnetic jerks finally reproduced and explained

Judging by what I see, jerks are reproducing all the time.

This is simply preliminary. It may or may not be correct.

What has been done in the study is to create a computer program that appears to produce effects very similar to the geomagnetic jerks.

It may or may not be the actual mechanism. The computer program produces phenomena that looks, in the program, very similar to what is observed.

The test to see if it is correct is to determine if the jerks can be predicted by using the information from the program.

If they can be predicted, it will be good confirmation that the computer program is reproducing a phenomena close to reality.

Haven’t thought of them in quite a while.

Whatever became of the GPS adjustment that was supposed to have people landing in Kansas?

Fasten your seatbelt, Dorothy, 'cause Kansas is going bye-bye!

Based on the headline, I thought it was going to be another article about Mitt Romney.

Magnetism is a great way to understand our current political environment.
Like attracts. Opposite repels. The pendulum effect explains an anomaly, the diminution of one pole to its opposite. Balance and harmony are achieved as the arch is completed.
The jerks are random elements such as Maxine and Mitt pulling and pushing the axis of the arch. Waves diminish as jerks are countered by stronger pushback.
The Donald provides a balancing effect by pushing back harder than the jerk, thereby cancelling and defeating the jerk.
This is the universal theory of dynamics.
