NASA’s AIM spacecraft is monitoring an outbreak of electric-blue clouds high above Antarctica. These are “noctilucent clouds” (NLCs). They form when wisps of summertime water vapor wrap themselves around meteor smoke, forming swarms of ice crystals at the edge of space.
If you think strange clouds in the atmosphere over remote Antarctica are of little practical interest, think again.
According to Spaceweather, researchers have discovered unexpected teleconnections between noctilucent clouds and weather patterns thousands of miles away.
Would you believe that winter air temperatures in Indianapolis, Indiana, are correlated with NLCs over Antarctica? It’s true.
