Voyager 2 hinted at a cyclone at Uranus’ south pole. Now Earth-based observations give the first direct evidence of a storm at the ice giant’s north pole.

NASA scientists have found strong evidence of a polar cyclone on Uranus for the first time. Researchers examined radio waves emitted from the ice giant and detected the phenomenon at its north ...

As the polar vortex weakens, a bomb cyclone appears. Bombogenesis, or bomb cyclones, occur when a sudden drop in pressure leads to the rapid intensification and strengthening of storms.

The weather during the week of Thanksgiving will get very interesting, with the remnants of a bomb cyclone and a polar vortex within a seven-day span. Skip Navigation. Share on Facebook; ...

Cavallo said tropopause polar vortices are sometimes present for months before an Arctic cyclone forms, while Arctic cyclones are usually only predicted several days in advance.
