NOAA’s P-3 hurricane hunter aircraft will fly a Tail Doppler Radar (TDR) mission into Hurricane Danny today. The P3 will depart at 2:00PM local time from Barbados and fly a seven hour mission. This is the first of a series of flights that will gather data every 12 hours. The proposed flight track is shown below. This type of flight track will give us the best data coverage in all quadrants of the storm. The Doppler radar data collected during this and future TDR missions will be transmitted in near realtime to NOAA’s hurricane weather forecast model. The data is then ingested into the model to improve the model’s intensity and track forecasts. The dots on the flight track (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.
