 Proposed NOAA 49 track |
Mission Plan :
NOAA 49RF will conduct a G-IV TDR pattern around Hurricane Arthur, which had intensified rapidly off the eastern coast of Florida and Georgia. The system was declared a hurricane less than 9 h earlier. The plan calls for a circumnavigation TDR pattern at 1, 1.5 and 2 degrees radius from the storm center. Dropsondes are staggered at every other turn point of the octagonal pattern. Visible satellite imagery (Fig. 1) shows that the center of circulation is less than 2 degrees from the South Carolina coast. This proximity to land is expected to limit sonde coverage on the northwestern side of the storm.
The G-IV will leave MacDill AFB, FL 1730 UTC on July 3rd and will recover back at MacDill AFB, FL by 2300 UTC the same day.

 Figure 2. Actual flight track |
The actual flight track is shown in Fig. 2. Takeoff was at 1714 UTC from Tampa. The aircraft landed in Tampa at 2253 UTC. 12 sondes were deployed.
Mission Evaluation :
A total of three radar analyses were created and transmitted in real time. A composite of these three analyses is shown in Fig. 3 at different altitudes. A total of 12 dropsondes were processed. The position used to center the TDR pattern was based on an earlier forecast. Because this position was not updated to the real-time storm position (which was to the west of the forecast position), the G-IV ended up flying over the eye and eyewall of Hurricane Arthur. Although this was not intended, it did provide for good coverage of the wind field in Arthur's inner core.

Problems :
No problems with the data collection systems were noted.
