Arthur Develops into the First Hurricane of the 2014 Atlantic Hurricane Season - July 14, 2014
Hurricane Arthur spawned from a disturbance (Invest 91L) that developed off the Southeast U.S. Coastline at the end of June. On the evening of June 30th, Invest 91L was upgraded to Tropical Depression One (TD 1) off the east coast of Central Florida. By the next morning, TD 1 was upgraded to the first named cyclone (Arthur) of the 2014 Atlantic hurricane season. Arthur slowly gathered strength and became the first July hurricane since Hurricane Alex (2010) on July 3rd. On the night of July 3rd, Arthur made landfall at Shackleford Banks between Cape Lookout and Beaufort, North Carolina as a Category 2 hurricane. After making landfall in North Carolina, Arthur weakened and raced off to the northeast ahead of an upper-level trough. Arthur made a second landfall on July 5th in Nova Scotia before the aforementioned upper-level trough overtook the strong extratropical cyclone.
TTU Ka-Band Mobile Radar Truck Showcased at AWEA Windpower 2014
National Wind Institute Director Dr. John Schroeder and TTUHRT members Dr. Brian Hirth, Jerry Guynes, Scott Gunter, and James Duncan recently attended the AWEA Windpower 2014 conference in Las Vegas, Nevada. TTUKa-2 was showcased in the Mandalay Bay exhibition hall for conference attendees to get an up-close look at the system and wind energy-related research being conducted at the National Wind Institute. The radar technology and its capability to help optimize current and future wind farms around the world was a hot topic according to Mike Barnard.
TTUHRT members publish dual-Doppler radar wake study article in Wind Energy
National Wind Institute Director Dr. John Schroeder and members Dr. Brian Hirth, Scott Gunter, and Jerry Guynes had an article published in Wind Energy this month titled "Coupling Doppler radar-derived wind maps with operational turbine data to document wind farm complex flows." The authors used innovative dual-Doppler (DD) radar techniques to acquire the first known DD measurements in a utility-scale wind farm. The DD radar measurements are compared with operational turbine data and successfully projected power output for several turbines within the wind farm. The methods and results within the study have the potential to improve current wake models, enhance wind resource assessment approaches, and provide real-time wind maps that create smarter wind turbines.
