Hurricane Frances (2004)
During Hurricane Frances, data were collected by DOW2 and DOW2 in the northern eyewall and eye of the storm. Direct onshore flow over the barrier islands and harbor provided an excellent opportunity to observe boundary layer structures as the flow first impinged on land. A 5.7 km baseline was established east of Fort Pierce, directly in the path of the right eyewall, the most intense portion of the storm. Gusts exceeding 50 m/s were observed at 10 m agl. Low level dual-Doppler scans were repeated every 10 seconds. This will permit ultra-high temporal resolution of the evolution of boundary layer wind streaks. Observations over or very near the destroyed Fort Pierce marina and the nuclear plant may prove valuable. Range resolution ranged from 13 to 38 m, with cross beam oversample resolution of approximately 30 m in the dual-Doppler lobes. See below for deployment locations (as well as part of the track of Frances) during this project.
