The Equatorial Electrojet

Caption

The equatorial electrojet is a naturally occurring flow of current approximately 100 kilometers (60 miles) above the Earth's surface. A new study shows it amplifies the effects of space weather near the equator, putting power grids at risk in regions previously thought to be less prone to space weather than high-latitude regions.
