MAGNETO-CORIOLIS WAVES
European Space Agency’s Swarm satellite mission has detected a completely new type of magnetic wave that generates across the outermost part of Earth’s outer core every seven years. According to, Nicolas Gillet, from the University Université Grenoble Alpes and lead author of the paper, “Geophysicists already theorised the existence of such waves, but they were thought to take place over much longer time scales than our research has shown. Measurements of the magnetic field from instruments based on the surface of Earth suggested that there was some kind of wave action, but we needed the global coverage offered by measurements from space to reveal what is actually going on. The waves called as "Magneto-Coriolis" waves because they move along the Earth’s axis of rotation, as per the Coriolis effect moving from East to West in tall columns that can travel up to 930 miles (1,500 kilometers) per year.
