  "id": "MLC-T-MET-007087",
  "term": "Magnetic storm",
  "field": "Meteorology and atmospheric science",
  "definition": "A period of rapid and intense variation in the Earth's magnetic field, caused by the interaction of the magnetosphere with a shock wave and cloud of plasma from the sun. These events are triggered by solar phenomena like coronal mass ejections or solar flares that send a surge of solar wind toward Earth. The strength of a magnetic storm is measured by the Disturbed Storm Time (Dst) index, with values below -50 nanoteslas indicating a storm.",
