Earth’s Magnetic Field Anomaly Growing – Satellites Reveal

Here’s a breakdown of the provided text, focusing on the key data about the south Atlantic Anomaly (SAA):

* What is the South Atlantic ⁣Anomaly? It’s a region where Earth’s magnetic field is weaker⁢ than expected and behaves strangely. Specifically, magnetic flux that should be emerging from the Earth’s core is instead reversing and going back‌ into the core.
* ‌ Why is‌ it ​happening? Scientists ​don’t know the exact cause, but they know ​the ‌magnetic field beneath ⁢the region isn’t behaving ⁤normally.
* How⁣ do we certainly know about it? ​ Data from the European space Agency’s Swarm satellite mission is helping scientists track the anomaly and observe its movement. Specifically, they’ve seen an area of reversed flux moving westward ⁤over Africa, contributing to‍ the weakening of the SAA.
* Possible Connection: ⁤ The⁢ anomaly might be linked to unusual structures deep within the Earth (specifically, the “weird blobs” mentioned ‌in the‌ linked article).
* Normal Magnetic Field: Earth’s magnetic field is generally dipolar – lines emerge in the south and dive in the north.The SAA disrupts​ this pattern.

In essence, the SAA is ‌a puzzling weakness and reversal in Earth’s magnetic field over the south Atlantic,⁢ and scientists are actively studying⁤ it to understand its origins and potential implications.
