As Edouard continued its northward motion east-southeast of Bermuda two NOAA P-3s and the G-IV collected airborne Doppler radar data to use in initializing and evaluating the HWRF model ,and as part of an Ocean Winds and Rain experiment. Included here you see images of the horizontal winds within 350 km of Edouard sampled from the tail Doppler radar on the two P-3 and G-IV aircraft during the afternoon of 15 September 2014. These images are at three altitudes (1 km, 3 km, and 7 km) and are a composite of winds from the P-3 and G-IV Doppler pattern around Edouard. Also plotted on each analysis are the locations of dropsondes deployed by the P-3 and G-IV (plotted using standard station symbols). These analyses show that Edouard still had a symmetric distribution of precipitation around the storm center at all altitudes. There is indication of a circulation center at all altitudes, with stronger winds 30-35 km north-northeast of the circulation center at 1-km altitude, rotating upwind (clockwise) with increasing height, indicative of increasing southerly flow with altitude. From 1-7 km altitude there is 5-10 km tilt to the northeast of the circulation center with height from 1- to 7-km altitude indicative of increasing southwesterly shear of the horizontal wind with height over the storm.
