Researchers Discover "Space Hurricane" in Upper Atmosphere


Hurricanes in the Earth’s low atmosphere are well known; however, disturbances resembling hurricanes had never before been detected in the upper atmosphere. “Until now, it was uncertain that space plasma hurricanes even existed, so to prove this with such a striking observation is incredible,” said Professor Mike Lockwood, a space scientist in the Department of Meteorology at the University of Reading. “Tropical storms are associated with huge amounts of energy, and these space hurricanes must be created by unusually large and rapid transfer of solar wind energy and charged particles into the Earth’s upper atmosphere. Plasma and magnetic fields in the atmosphere of planets exist throughout the Universe, so the findings suggest space hurricanes should be a widespread phenomenon.”

“This study suggests that there are still existing local intense geomagnetic disturbance and energy depositions which are comparable to that during super storms,” he added. “This will update our understanding of the solar wind-magnetosphere-ionosphere coupling process under extremely quiet geomagnetic conditions. In additional, the space hurricane will lead to important space weather effects like increased satellite drag, disturbances in High Frequency (HF) radio communications, and increased errors in over-the-horizon radar location, satellite navigation and communication systems.”
