A space hurricane was furious for nearly eight hours on August 20, 2014, swirling hundreds of miles above Earth’s magnetic north pole, according to a study published in the journal on February 22. Nature Communications..
Made from the tangled mess of Magnetic field lines The hurricane was invisible to the naked eye, but four meteorological satellites that passed through the North Pole detected the formations in the same way as a typical land hurricane, the study authors write. The space hurricane had a quiet “eye” in the center and was shaped like a funnel surrounded by several swirl arms that rotated counterclockwise. plasma (Ionized gas found throughout the solar system, including the Earth’s atmosphere).
Space hurricanes have caused electrons to fall directly into the Earth’s upper atmosphere instead of raining water.
“In the past, it was uncertain that even a space plasma hurricane existed, so it’s unbelievable to prove this with such impressive observations,” said a study by a space scientist at the University of Reading, UK. Co-author Mike Lockwood said. Said in a statement.. “Tropical cyclones are associated with large amounts of energy, and these space hurricanes need to be created by the unusually large and rapid movement of solar wind energy and charged particles into the Earth’s upper atmosphere.”
Using a 3D model of the hurricane, the researchers hypothesized that the formation resulted from a complex interaction between the solar wind (a high-speed strong wind of plasma emitted regularly from the sun) and a magnetic field above the Arctic. ..
Although this is the first observed space hurricane, researchers assume that these “weather” systems could be a common event on planets with magnetic shields and plasmas in the atmosphere. I will.
“Since the plasma and magnetic fields in the planet’s atmosphere are present throughout the universe, the findings suggest that space hurricanes should be a widespread phenomenon,” Rockwood said.
Should I be afraid of space hurricanes? Probably not. Researchers have pointed out that upper atmospheric phenomena pose little threat to our planet, but it is an existing space weather effect, for example by increasing the drag of satellites or disrupting GPS and wireless communication systems. May affect.
