Mission Plan :
Fly another TDR/genesis-type pattern into T.S. Danny, which has minimally intensified according to NHC. The system is still highly disorganized, with an exposed LLCC displaced about 120 nm from any deep convection and shear still impacting system (Fig. 1). Visible animation shows a midlevel circulation center (MLCC) developing in convection to the east. Fly a butterfly pattern anchored on the MLCC in the convection (Fig. 2). Set up IP further to the west (about 180 nm) to traverse low-level swirl. Drop sonde at the IP on the W side of the swirl, then over low-level center. Continue pattern with 120 nm legs, end up on the NW side. Drop sondes at turn points, midpoints, and first center 'pass' at flight-level. Drop AXBT's at integer longitudes on ferries, plus at turn points. Fly the pattern at 15,000 ft. prior to reaching the LLCC, then descend to 10,000 ft.

Mission Evaluation:
To the extent that the mission was to sample a system struggling to organize in shear and dry air, this flight accomplished its objectives. We targeted convection to the east of the LLCC instead of the LLCC itself, which was devoid of scatterers. Radar analyses produced in real time showed very complex structures, including multiple vortices of different horizontal scale at different altitudes. Ultimately the system was unable to reform in convection, and likely will dissipate soon. Intensity guidance has been very diverse, with mesoscale models predicting Danny to intensify to hurricane strength. This case should provide good data to compare with models to find error sources in the intensity forecasts.
Problems :
There were no problems with the flight.
