The Earth’s magnetic field experiences unpredictable, rapid, and intense anomalies that are known as geomagnetic jerks. The mechanisms behind this phenomenon had remained a mystery until advanced numerical geodynamo simulations could simulate the rapid hydromagnetic wave dynamics that causes these anomalies. This research was published in Nature Geoscience on 22 April 2019.
