On both May 19 and May 20, 2013, NSSL researchers collected data on storms that produced tornadoes using both the NWRT Phased Array Radar (PAR), and the mobile dual-polarized radar.
The experimental Tornado Debris Signature algorithm uses dual-pol radar data to map areas of debris.
Today, researchers launched the Mesoscale Predictability EXperiment (MPEX) field project to collect data on pre-storm and post-storm environments in an effort to better predict where and when thunderstorms will form. MPEX runs from May 15 – June 15, and is funded by the National Science Foundation.
During the 2013 central Oklahoma severe weather season, researchers will demonstrate and evaluate new capabilities developed for the NOAA National Weather Radar Testbed Phased Array Radar (NWRT/PAR).
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.
