Outer Core Flow Reversals and Chaotic Dynamics
Key Questions
What does Swarm satellite data reveal about the Pacific outer core flow?
Swarm data confirms a reversal in outer core flow beneath the Pacific that began in 2010. This reversal involved an eastward surge that has been weakening since 2020.
How has the outer core flow behaved between 1997 and 2025?
The period shows chaotic dynamics with the 2010 reversal followed by weakening eastward flow since 2020. These patterns indicate ongoing turbulence in the outer core.
What does the core flow reversal signal about geomagnetic activity?
The reversal and associated turbulence are viewed as precursors to geomagnetic instability and potential excursions. This aligns with updates from S0 News on May 25.
When did the shift in outer core circulation under the Pacific start?
The shift began in 2010 according to multiple reports on Earth's deep interior circulation changes. It has been described as an unexpected reversal of molten core flow.
How might these core changes affect Earth's magnetic field?
The turbulent flow reversal contributes to instability that can drive geomagnetic excursions. Related articles link the 2010 event to broader magnetic field dynamics.
Swarm data confirms 2010 Pacific outer core flow reversal; eastward surge weakening since 2020 amid chaotic 1997-2025 behavior. Signals turbulence driving geomagnetic instability and excursions. S0 News May 25 update reinforces this as a key precursor.
