The 2005 TTUHIT Project succeeded in collecting high-resolution datasets from Hurricanes Katrina and Rita. The data obtained from these two cyclones represent a high percentage of the complete wind records from each storm, as conventional observation platforms typically failed. The implementation of the turbulence experimental plan, as discussed in section 3, was not successful in sampling hurricane winds. On each occasion, the tower array was located outside the radius of maximum winds. The eyewall experimental plan was used with success for Hurricanes Katrina and Rita, although with some modifications in each case. Technical problems did not allow for a complete data record to be obtained from Vacherie, LA during Hurricane Katrina and Orange, Texas during Hurricane Rita. The successful deployments during Hurricanes Katrina and Rita yielded interesting results regarding the intensity of each storm. The wind speed data collected from each storm revealed a similar wind field. Although Hurricane Katrina resulted in much more significant damage and loss of life, mainly due to catastrophic storm surge flooding, the observed peak wind speeds were quite similar to Hurricane Rita. It should be noted that the Hurricane Rita deployment sites each exhibited a roughness length near the open exposure classification (Davenport, 1960). The observed peak one-minute sustained wind in each case was substantially lower than the official landfall intensity, however the data collected during Hurricane Katrina at the Slidell and Stennis locations are not necessarily representative of an open exposure. Direct measurements were not made along the immediate coastline, all deployment sites were at least 5 km inland for both Hurricane Katrina and Hurricane Rita. Peak instantaneous gusts during each storm however, did approach the official landfall intensity. The 2005 Atlantic Hurricane Season shattered all known historical records and given the increase in tropical activity the likelihood of landfalls in the continental United States will increase as well. The need exists for continued collection of complete meteorological data records from landfalling tropical cyclones.
