NSSL tornado climatology expert, Harold Brooks has written a blog post about the remarkable absence of tornado activity during the 12-month period from May 2012 to April 2013.
A team of scientists, including NSSL’s Dave Turner published a new study in Nature that showed how clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point.
High atop the Greenland Ice Sheet, cloudy skies portend warmer temperatures and higher winds. These clouds alter the surface energy budget, diminish the strong near-surface atmospheric stability, and precipitate ice crystal to the surface.
NSSL and collaborators will leverage new technology including dual-polarized radar observations and a precipitation reporting mobile device app to improve forecasts of winter weather during February and March.
February 5-7 at the National Weather Center.
