Doppler radar quick-looks from 10:00 AM P-3 flights into Hurricane Edouard, 17 September 2014

As Edouard continued its northeastward motion east-northeast of Bermuda a NOAA P-3 collected airborne Doppler radar data to use in initializing and evaluating the HWRF model. 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 midday of 17 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 patterns 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 still had a relatively symmetric distribution of precipitation around the storm center at all altitudes. There is indication of a circulation center at all altitudes, with stronger winds 35-40 km southeast of the circulation center at 1-km altitude, rotating upwind (clockwise) with increasing height, indicative of increasing westerly flow with altitude. There is also indication of a secondary wind maximum 75-80 km south-southeast of the circulation center at all altitudes. From 1-6 km altitude there is  10-15 km tilt to the east of the circulation center with height from 1- to 6-km altitude indicative of increasing westerly shear of the horizontal wind with height over the storm.
