As Edouard reached hurricane strength and continued it slow northward motion southeast of Bermuda a NOAA P-3 collected airborne Doppler radar data to use in initializing and evaluating model guidance and as part of an Ocean Winds and Rain experiment. Included here you see images of the horizontal winds within 300 km of Edouard sampled from the tail Doppler radar on the P-3 aircraft during the early afternoon of 14 September 2014. These images are at three altitudes (1 km, 3 km, and 6 km) and are a composite of winds from the P-3 Doppler pattern around Edouard. Also plotted on each analysis are the locations of dropsondes deployed by the P-3 (plotted using standard station symbols). These analyses show that Edouard had a relatively symmetric distribution of precipitation at all altitudes,. There is indication of a circulation center at all altitudes, with stronger winds 25-30 km northeast of the circulation center at all altitudes. From 1-6 km altitude there is practically no tilt of the circulation center with height indicative of very little shear of the horizontal wind over the storm at this time.
All the Edouard radar composites at 0.5-km height resolution are available at http://www.aoml.noaa.gov/hrd/Storm_pages/edouard2014/radar.html
A NASA Hurricane and Severe Storm Sentinel (HS3) Global Hawk mission was conducted into Edouard from 1102 UTC 14 September to 1050 UTC 15 September, overlapping this NOAA P-3 mission, dropping 80 dropsondes in a combination lawn mower and butterfly pattern over Hurricane Edouard.
