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. "This is the season for noctilucent clouds in the southern hemisphere," says Cora Randall, a member of the AIM science team at the University of Colorado's Laboratory for Atmospheric and Space Physics."They typically appear in November and persist until February. We began seeing clouds this year on Nov. 21st." If you think strange clouds in the atmosphere over remote Antarctica are of little practical interest, think again. 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. Understanding how these long-distance connections work could improve climate models and weather forecasting. http://spaceweather.com/
