The first observations of a space hurricane have been revealed in Earth’s upper atmosphere, confirming their existence and shedding new light on the relationship between planets and space.
Hurricanes in the Earth’s lower atmosphere are known, but they had never been detected before in the upper atmosphere.
An international team of scientists led by Shandong University in China analyzed observations made by satellites in 2014 to reveal a long-lasting, lower-atmosphere-like hurricane in the polar ionosphere and magnetosphere with Surprisingly large energy and momentum deposits despite extremely calm geomagnetic conditions.
The analysis created a 3D image of the swirling mass of plasma 1,000 km wide several hundred km above the North Pole, raining electrons instead of water.
Professor Qing-He Zhang, senior author of the research at Shandong University, said, “These characteristics also indicate that the space hurricane leads to large and rapid deposition of energy and flux in the polar ionosphere. during an otherwise extremely calm geomagnetic condition, suggesting that current geomagnetic activity indicators do not correctly represent…
